Introduction

Hello fellows from all over the world.

I've decided to start a blog about my own little 3D Engine I've started making.

Why a 3D Engine you might ask? Well, I got bored a while ago. Bored with all the PHP and Access shite at school. Sounds familiar eh?

I just wanted to know how the 3D stuff of all these epic games worked, and well, I just started creating my own. Just as simple as that, start your own, you might think. Well, it is not.

It's just called 'Engine' for now, and it will do for now. Enough for the personal stuff, lets race ahead to my actual latest version (I started making this blog a tad too late).

Why To Use Tangent Space

You might've been wondering why you see lots of people doing their vector calculations in what they call texture or tangent space. Why can't they just do it in World space for example?

Well, because they want their special texture maps to be portable.

Let's take normals for example: 3D vectors which can be stored in textures to provide detail normals for every pixel on a texture (texel). Textures which store normals are called normal or bump maps. Here's an example of a normal map of a brick wall:

This image has three channels: R, G and B. They're used to store the X, Y and Z amount of a normal that's supposed to be at that given texel. This normal can be used to change surface lighting without having to add geometry. The only downside is that the object will still look flat from a side: it's just a trick to change lighting response, not to add actual depth. Lighting effects are changed because these normals are used in the color calculations, not the linear ones passed by the Vertex Shader.

Now about the colors: red equals to normals pointing along (tangent to) the surface, green equals to normals pointing left (bitangent to) and blue equals to normals pointing up away from the surface.

A pure blue (0,0,255) pixel (the perfect surface normal) will be our test subject.

Let's say we were using this vector as a world space normal. That would work perfectly fine for a surface lying flat on its back. The texture reader would read (0,0,255) and determine the current normal pointing 100% up in World space. Then imagine an object on its belly with this texture. The GPU reading the texture will still read (0,0,255) believing the normal is still pointing up in World space. This is not the case, since the object itself has rotated. Oops.

Looks like we can't just pluck world normals out of a texture, because world normals are object orientation dependant. The normals are relative to the surface the texture is applied on. So, we need to know surface orientation to be able to use these normals. There's no way to store portable world normals in a texture.

But there's always hope: just convert your data which is in stored in World Space to Tangent space.

[Direct3d Hlsl] Normal Mapping Tutorial

For an explanation about why to use tangent space, read this tidbit of text.

Let's assume we're using Direct3D and HLSL.

Converting to Tangent (or texture) space

Normals stored in the texture are surface orientation dependent and are stored in what's called Tangent Space. But all the other lighting components such as view direction are supplied in world space. Because we can't use world space, why not convert every lighting component we need to compare the normal with, to this format called tangent space? Why not compare apples to apples?

Changing coordinate systems requires transformation. I'll just skip the hardcore math, but what I do want to explain here is that we need a matrix to transform world to tangent space. Just like we need a matrix to get world space from object space, we need a matrix to convert to tangent space. Remember this:

• We need the surface orientation, because that's where the texture normals depend on.
• We know everything about our surface (a triangle).
• Any lighting component we need in PS (lightdir,viewdir,surfacedir) needs to be multiplied by the resulting matrix.

/* We need 3 triangle corner positions, 3 triangle texture coordinates and a normal. Tangent and bitangent are the variables we're constructing */


// Determine surface orientation by calculating triangles edges

D3DXVECTOR3 edge1 = pos2 - pos1;

D3DXVECTOR3 edge2 = pos3 - pos1;

D3DXVec3Normalize(&edge1, &edge1);

D3DXVec3Normalize(&edge2, &edge2);

// Do the same in texture space

D3DXVECTOR2 texEdge1 = tex2 - tex1;

D3DXVECTOR2 texEdge2 = tex3 - tex1;

D3DXVec2Normalize(&texEdge1, &texEdge1);

D3DXVec2Normalize(&texEdge2, &texEdge2);

// A determinant returns the orientation of the surface

float det = (texEdge1.x * texEdge2.y) - (texEdge1.y * texEdge2.x);

// Account for imprecision

D3DXVECTOR3 bitangenttest;

if(fabsf(det) < 1e-6f) {

// Equal to zero (almost) means the surface lies flat on its back

tangent.x = 1.0f;

tangent.y = 0.0f;

tangent.z = 0.0f;

bitangenttest.x = 0.0f;

bitangenttest.y = 0.0f;

bitangenttest.z = 1.0f;

} else {

det = 1.0f / det;

tangent.x = (texEdge2.y * edge1.x - texEdge1.y * edge2.x) * det;

tangent.y = (texEdge2.y * edge1.y - texEdge1.y * edge2.y) * det;

tangent.z = (texEdge2.y * edge1.z - texEdge1.y * edge2.z) * det;

bitangenttest.x = (-texEdge2.x * edge1.x + texEdge1.x * edge2.x) * det;

bitangenttest.y = (-texEdge2.x * edge1.y + texEdge1.x * edge2.y) * det;

bitangenttest.z = (-texEdge2.x * edge1.z + texEdge1.x * edge2.z) * det;

D3DXVec3Normalize(&tangent, &tangent);

D3DXVec3Normalize(&bitangenttest, &bitangenttest);

}

// As the bitangent equals to the cross product between the normal and the tangent running along the surface, calculate it

D3DXVec3Cross(&bitangent, &normal, &tangent);

// Since we don't know if we must negate it, compare it with our computed one above

float crossinv = (D3DXVec3Dot(&bitangent, &bitangenttest) < 0.0f) ? -1.0f : 1.0f;

bitangent *= crossinv;

/* and add it to our model buffers */

We need to create a 3x3 matrix to be able to use it to convert object normals to surface-relative ones. This matrix should be built by adding the three components up in a matrix, and then transposing it in de Vertex Shader:

// tangentin, binormalin and normalin are 3D vectors supplied by the CPU

float3x3 tbnmatrix = transpose(float3x3(tangentin,binormalin,normalin));

// then multiply any vector we need in tangent space (the ones to be compared to

// the normal in the texture). For example, the light direction:

float3 lightdirtangent = mul(lightdir,tbnmatrix);

Then we're almost done. The only thing we need to do now is pass all the converted stuff to the Pixel Shader. Inside the same Pixel Shader retrieve the normal from the texture. Now you're supposed to end up with for example the light direction in tangent space. Then do your lighting calculations as you would always do, with the only exception being the source of the normal:

// we're inside a Pixel Shader now
// texture coordinates are equal to the ones used for the diffuse color map
float3 normal = tex2D(normalmapsampler,coordin);


// color is stored in the [0,1] range (0 - 255), but we want our normals to be
// in the range op [-1,1].
// solution: multiply them by 2 (yields [0,2]) and substract one (yields [-1,1]).
normal = 2.0f*normal-1.0f;


// now that we've got our normal to work with, obtain (for example) lightdir 
// for Phong shading
// lightdirtangentin is the same vector as lightdir in the VS around 
// 20 lines above
float3 lightdir = normalize(lightdirtangentin);


/* use the variables as you would always do with your favourite lighting model */

[Direct3d] Handling Lost Devices

Hello and welcome to another topic about 3D programming.

Let's suppose we're programming in Direct3D9.

Today I'll be talking about one of the most annoying problems found in 3D applications: lost devices.

Lost Devices
First things first: what's a lost device anyway? When a device goes in a lost state it means it can't place it's results anywhere. It then isn't able to put it's buffers to any place on screen. This might happen when a user Alt Tabs out of a fullscreen game for example: the GPU then can't place it's frames anywhere anymore, so it becomes lost.

Lost devices can't be fully accessed by the Direct3D API anymore. For example, draw calls will return D3DERR_INVALIDCALL instead of D3D_OK (success). This means you can't tell the GPU to do anything useful anymore. To get it working again, you need to reset it.


Resetting your GPU Card
Just to assure you, you don't need to reset your PC or anything, you only need to empty it's memory manually by software (API). Remember, most of Direct3D's API isn't working anymore. There's just about five calls we can make:

• devicepointer->TestCooperativeLevel(). Think of this one as a doorbell. No one coming at the door (not returning D3D_OK)? Your GPU is lost.
• devicepointer->Reset(). This one will wipe GPU RAM and reset all States you've set (like SetRenderState and SetSamplerState).
• resourceinheritingfromIUnknown->Release(). You need to tell the GPU you don't need resources in GPU RAM anymore with this function. You can't even forget a single resource pointer: it will make your app crash when reseting.
• resourcebackedupincpuram->OnLostDevice(). Call this on any object that has a backup in CPU RAM.
• resourcebackedupincpuram->OnResetDevice(). Call this on any object that has a backup in CPU RAM.

As I've said, you need to empty the GPU's memory before you can reset it. One minor note first though: as any experienced PC user does *cough* you make backups *cough*:

• Resources put in D3DPOOL_DEFAULT are no-backup resources and can be found in the best RAM possible (GPU RAM). If we run out of GPU RAM, we put it in CPU RAM. If we can't store it there, leave it on the drive, crash, or put it in Page File. Clear enough.
• But we've also got D3DPOOL_MANAGED. These resources are copied to CPU RAM, and only when needed they get copied (not moved) to GPU RAM. This means there's always a backup available of these resources.

Let's put together a TODO-list of our reset then. What needs to be done is (in this order):

1. Release() any resources that are stored in GPU RAM (D3DPOOL_DEFAULT).
2. Put any resources that are stored both in GPU RAM and in CPU RAM (D3DPOOL_MANAGED) on hold and remove them from GPU RAM. Do this by calling OnLostDevice() on them.
3. Reset the device with devicepointer->Reset(D3DPRESENT_PARAMETERS).
4. Then tell all resources backed up in CPU RAM to copy back to GPU RAM by calling OnResetDevice() on them.
5. Recreate your resources that were put in D3DPOOL_DEFAULT.

An example

Let's say we've got ourselves a basic engine with the following resources:

• A GPU font, called ID3DXFont, used to draw our tooltip text on the GPU.
• The FX Framework, called ID3DXEffect, used to modify shader parameters.
• A shadowmap (color + depth), created by CreateTexture and CreateDepthStencilSurface. These are IDirect3D9Surface's and a IDirect3D9Texture.

In this case, the reset sequence will look like this:

void D3D::resetD3D() {

// Saveable resources in D3DPOOL_MANAGED

font->OnLostDevice();

FX->OnLostDevice();

// Unsavable resources that don't have a backup

ShadowTex->Release();

ShadowTexTopSurface->Release();

ShadowDepthTopSurface->Release();

// Let's throw everything away

d3ddev->Reset(&d3dpp);

// And copy the CPU RAM resources to GPU RAM

font->OnResetDevice();

FX->OnResetDevice();

// Recreate D3DPOOL_DEFAULT stuff

initD3D(1);

}

I hope this will be clear enough, and if not, tell me!

[Hlsl] Parallax Mapping Tutorial

If you don't have a clue what Tangent Space is about, read this.

This time, Parallax Mapping will be discussed.

Theory

Well, what is a Parallax supposed to be anyway? It's quite a common phenomenon. Actually, it's so common most people wouldn't even notice it as anything out of the ordinary. Let's take a spedometer as a common example for people not sitting behind the steering wheel.

Let's suppose dad's driving at 100km/h. His spedometer also shows that amount more or less. But mom sitting next to him, will see him driving a tad slower. Why, you might ask? Well, it's because dad's viewing the spedometer from the front, so the pointer will sit on top of '100'. From the point of view of mom, it'll be hovering above, let's say, 95km/h. This is because she is viewing it at an angle and there's a depth difference between the needle and the text.

here.


/* VERTEX SHADER
outVS.toeyetangent = mul((camerapos - worldpos),tbnMatrix);
*/


// PIXEL SHADER

float3 toeyetangent = normalize(toeyetangentin);


// The only thing we're doing here is skewing textures. We're only moving 
// textures around. The higher a specific texel is, the more we move it. 
// We'll be skewing in the direction of the view vector too.


// This is a texture coordinate offset. As I said it increases when height
// increases. Also required and worth mentioning is that we're moving along with
// the viewing direction, so multiply the offset by it.
// We also need to specify an effect multiplier. This normaly needs to about 0.4
float2 offset = toeyetangentin.xy*height*0.04f;
texcoordin += offset;


In its most basic form, this is all you need to do Parallax Mapping working. Let's sum things up, shall we?

• Textures lack depth. Depth is necessary to bring back a 3D feel to it.
• An important part of the depth illusion is Parallax. We want to bring it back into our textures.
• To do that, we need to obtain texel depth and the viewing direction. The viewing direction needs to be supplied in Tangent Space to the pixel shader.
• To do that we need to supply normals, binormals and tangents to the vertex shader. Combining these to a matrix and transposing it gives us the opportunity to transform from world to texture space.
• Then supply texture coordinates and the tangent space view vector to the pixel shader.
• Then sample depth from a regular heightmap. Multiply it by the view vector.
• And tada, you've got your texture coordinate offset. You're then supposed to use this texture coordinate for further sampling.

Let's post a couple of screenshots then. First the one without any parallax mapping.

Now it does include a Parallax Map. It uses a multiplier of 0.4 and a single sample.

Yes, a single sample is all you need. No need to do PCF averaging or anything. Just a single tex instruction per pixel. But as you can see in the latter picture, there are some minor artifacts, especially on steeper viewing angles. To partially fix this, you need to include an offset constant, like this:

float2 offset = toeyetangentin.xy*(height*0.04f-0.01f);

texcoordin += offset;

With this result:

Well, that's pretty much all there is to it. Have fun with it!

Dev-C++ 4.9.9.3 Released

After a couple of years working with this fast and portable C/C++ IDE, I've decided to give it an update. That's because the compiler was getting ancient, and it contained a few bugs here and there. It took a while to get the hang of Delphi, but hereby I present to you Dev-C++ 4.9.9.3:

Changes - Version 4.9.9.3 - 24 Juni 2011

• Upgraded the Default Compiler to GCC 4.5.2.
• When encountering an error, Dev will now point you to the error line and (new) positions the cursor next to it.
• Added new -march optimization options (core2, k8-sse3, amdfam10). Also added 'native' and 'generic'.
• Cleaned up the explicit -m(some instruction set) options, and added some important ones.
• Cleaned up the TODO viewer.
• Fixed a bug in the GCC output parser: it used to read 1 byte too much afer the \0 of each line, causing crashes.
• Added a column column in the Compiler log.
• Tweaked the default settings. Enable line numbers by default for example.
• Fixed a bug in the Compiler Set creator: it didn't feel like storing command line options for each Compiler.
• Added more UI controls for frequently used GCC flags like -Wall, -Wextra and -pedantic.
• Moved warning related flag options to a new section called 'Code Warnings'.
• Removed the silly optimization controls. Now has a proper None/Low/Med/High combobox.
• Updated the default directory listings to GCC 4.5.2's directories.
• Removed the [Compiler] section from the ini file. Instead of saving the current Compiler Set twice, it saves a Compiler index to refer to.
• By default GCC4 omits required runtime DLL's from executables. I told it to link them by default.
• And some more stuff I forgot about.

Important notices

1. The options format has changed. If you want to reuse an old config file (NOT recommended), or, more importantly, when you're overriding Compiler Options in your project, you need to re-set these project settings once and save the project. You'll then have an updated 4.9.9.3 project file.
2. This version has GCC built-in instead of being an aditional package. It also contains D3D9/10/11, GDI, Win32 and OpenGL headers and libraries in that flavor.

Download
The setup can be downloaded here. The source code can be found here.


Problems

• FIXED: There seems to be a persoalan with the default relative include paths not being used properly. I seriously need to fix that soon (this weekend probably, after vacation). Together with a few more things to do, I of course also need to post the source code somewhere.

Dev-C++ 4.9.9.4 Released

Time for an update then. The last version was not-so portable in many ways. This one is. Together with doing a lot of portablizating, I've done a bunch of cleaning up, housekeeping and restyling.

Changes - Version 4.9.9.4 - 12 Juli 2011

• Added a %path% macro to every path. Use this string in the config files to add relative paths to Compiler Directories.
• Fixed a bug in the Code Completion Cache Creator (CCCC :D): it used to add 2 copies of every file (one relatively referred to and one referred to with a full path).
• Cleaned up a few duplicate and unused headers and binaries. The installer is now a whopping 200KiB smaller.
• Updated the make.exe searcher to check for GCC 4.5.2's make.exe.
• Added a few install profiles: minimalist and portable.
• Fixed a few grammar errors.
• Updated the About window.
• Added an icon to the installer.

Important notices

2. This version has GCC built-in instead of being an aditional package. It also contains D3D9/10/11, GDI, Win32 and OpenGL headers and libraries in that flavor.
3. This version is now fully portable. If you also don't want Dev to leave anything behind in the registry, please select "Portable" or "Minimal" in the setup options.

Download
The setup can be downloaded here (includes full and portable versions). The source code can be found here.


Problems

• FIXED: Need to add some processing code for a few rare output messages new to GCC 4.

Dev-C++ 4.9.9.5 Released

Yes, another update. This one comes with a few more urgent fixes and a portable version (the previous setup left some marks on PC's) can be downloaded in a zip format.

Changes - Version 4.9.9.5 - 16 Juli 2011

• Added column reporting for a few more error types.
• Made a proper portable version this time: it comes in a 7zip file, saving a few more registry entries compared to 4.9.9.4's portable setup.
• The uninstaller now adds itself to Windows' "Programs and Features" list.

Problems

• FIXED: The NSIS installer overestimates the installation size before unpacking by 50MiB. Don't have a clue why.
• FIXED: Some old (pre-4.9.9.3) setup code forces users to not install Dev in a path which includes spaces. However, when I tried running the portable version from inside "Program Files (x86)", everything worked just fine. Bottom line: I need to do some housekeeping in that NSIS code.

Dev-C++ 4.9.9.6 Released

Well, times for some fixes then. This version fixes all the bugs I'm aware of and comes with an upgraded versioning system.

Changes - Version 4.9.9.6 - 20 Juli 2011

• Fixed the language option in the executable information tab. It didn't properly set the listbox to the saved setting (losing settings upon next save).
• Fixed a bug in the file association code: icons were missing.
• Lines like 'in member function', 'in constructor' and 'in destructor' are now properly formatted in the Compiler Tab (no line and col numbers anymore).
• Added line and column formatting for 'In static member function'.
• Fixed the file version string: it now keeps in sync with incremented build numbers.
• The spin edits which control the Project file version are now kept in sync with the strings below.
• Added an option to synchronize product and file versions.
• Set the default installation directory to C:\Program Files (x86)\Dev-Cpp instead of C:\Dev-Cpp.

Problems

• FIXED: 'Candidates are' is gone when compiler suggests functions.
• FIXED: 'include\sys\' and 'include\' auto-include directories are conflicting.
• FIXED: Current line and column are not set when opening a file.
• FIXED: error: (instead of note:) Candidate is: is not properly formatted.

Dev-C++ 4.9.9.7 Released

This one fixes some urgent stuff I found with the debugger together with a load of other stuff. Oh, by the way, this version has been tested extra long and comes with the first user reported bug!

Changes - Version 4.9.9.7 - 26 Juli 2011

• Function candidates are now properly listed and formatted.
• When code completion was disabled, block tabs/untabs weren't working.
• Added formatting for the rare 'candidate is' (when there's one candidate of course) message.

Dev-C++ 4.9.9.8 Released

This one is the last one developed in my lots of free time. Got a job now and I'm going to college within a month, so I probably won't be fixing as fast as before. But nevertheless, this version comes with yet another bunch of fixes.

Changes - Version 4.9.9.8 - 1 Augustus 2011

• Fixed the uninstallers name: it used to report '4.9.9.5'.
• Added formatting for 'unknown escape sequence:'.
• Portable configurations are now saved in .\config\ instead of '.\'. Looks much cleaner this way.
• The Simple Window example now works correctly.

Dev-C++ 5.0.0.0 Released

And here it is. The long promised Dev-C++ version 5.0, or 5.0.0.0. As suggested by a user, I've restyled the UI to make up for the major version change. Luckily, that's not all. As usual, a big pile of bugs have been fixed. Enjoy!

Changes - Version 5.0.0.0 - 27 Augustus 2011

• Restyled pretty much everything.
• Reorganized a few windows to make better use of space.
• Several SynEdits now do not have an infinitely long scrollbar anymore.
• The splash screen now does not show up behind the tooltips anymore.
• Improved startup speed for the New Look theme.
• Updated the splash screen text.
• Added more keyboard shortcuts to rightclick menus.
• Removed everything XPMenu related. This shaves off about 7000 lines of code and makes Dev a bit faster.
• Added a bunch of code insertion templates. For example, WinMain, WindProc and a do-while() loop.
• Added copy all to right click menus of the rollout message sheet.
• A bunch of Copy hidangan items now listen to shortcuts like Ctrl-C too.
• Tab shortcuts now use Tabs instead of Shift-Ctrl-I and Shift-Ctrl-U (who came up with that fingerbreaking combination anyway?).
• Removed a few borders around some tabs below, increasing used space and cleaning the UI up.
• The Fullscreen close button is now visible again.
• Removed a few deprecated components like TBevel.
• Added Save all to rollout rightclick menus.
• Improved layout of some Project Options tab and the welcome form.
• You can now assign any combination of tab to any shortcut item you like.
• I have to admit I've lost track of a lot of changes.

Important notices

1. The options format has changed. If you want to reuse an old pre-4.9.9.3 config file (NOT recommended), or, more importantly, when you're overriding Compiler Options in your project, you need to re-set these project settings once and save the project. You'll then have an updated 4.9.9.3+ project file.
2. This version has GCC built-in instead of being an aditional package. It also contains D3D9/10/11, GDI, Win32 and OpenGL headers and libraries in that flavor.
3. This version is now fully portable. If you also don't want Dev to leave anything behind in the registry, please select "Portable" or "Minimal" in the setup options.
4. For ultimate portable programming, please launch devcppPortable.exe.lnk located in the main folder of the portable zip download. This will make dev save its configuration files in the same folder as the executable.

Problems / Upcoming changes / TODO

• TODO: Implement C++0x suggestions by Xazax.
• TODO: Fix the mysterious crash reported by mdiz.
• TODO: Fix the bug reported by Anonymous (first comment on 4.9.9.8).
• FIXED: The Delete key now does not get hijacked by the project browser anymore.
• FIXED: When nothing is selected, the tab key now puts a tab instead of doing nothing.
• FIXED: Dev-C++ now shows how long compiling took.

Dev-C++ 5.0.0.1 Released

Dev-C++ 5.0.0.4 Released

Time for an update then. The biggest addition is the updated rightclick sajian of the editor, which features a variable browser. Also, the guys at MinGW have ported a newer branch of GCC, so I've added it to Dev.

Changes - Version 5.0.0.4 - 25 September 2011

• Upgraded the compiler to GCC 4.6.1.
• The main tab control now has the optional (check Environment options) ability to spread tabs over multiple lines.
• Added Goto Declaration and Goto Definition buttonsto the editor right click menu. These buttons make code navigation much easier.
• The old code for Ctrl+Click now uses the new code for the buttons and uses two-way navigation.
• Added Profiling to the Compiler toolbar.
• Removed the useless About/Help toolbar.
• The splash screen now shows what Dev is currently loading.
• Code Completion Cache can now also be browsed through.
• Added icons for profiling options and added them to the compiling toolbar.
• Updated the Incremental Search window: it now has a previous and next button.
• Corrected a few regression bugs in the class scanner.
• Fixed a bug in the tooltip content generator.
• And much more minor stuff...

Dev-C++ 5.0.0.5 Released

After 12 beta's, I've finally decided to release 5.0.0.5. The biggest addition is the rewritten tooltip generator. I've also decided to dump make.exe from the binary directory, making an install 1.2MiB smaller.

Changes - Version 5.0.0.5 - 24 Oktober 2011

• Rewritten the tooltip generator. It now uses better code scanning techniques and does not show up above what you were typing anymore.
• Brace completion is now disabled inside strings and comments. It now also supports closing the < character.
• The tooltip now also works when typing foo[bar].member and hovering above member.
• The empty project now contains an empty Untitled unsaved file. Why would anyone NOT want or need that?
• The function tooltip now also displays tips for completed and empty function parameter bodies.
• The < character is now only inserted in lines starting with '#include'.
• Highlighting checks in plain files now do not cause Dev to crash.
• The Tips of the Day are back again!

• Projects are now saved upon creation.
• Fixed two out-of-bounds errors in tooltip generation and code completion.
• The source code is now more user friendly (DevCpp.dpk wouldn't compile straight away since some version), and 50% smaller.
• Dev can now automatically log compiler messages to disk (the option can be found in Project Options >> Build Options).
• The obj output directory now does not get created in the wrong 'current directory' in rare cases.
• Dependency checking and compile delays are now saved, and on a per-compiler basis.
• Restyled the editor tooltip balloon.
