[PB4.30] Pixel/Vertex shaders examples DirectX/OpenGL

Post by djes »

This is an example of pixel shaders taken from the ogre site and adapted to Purebasic.

Download there : http://djes.free.fr/purebasic/shader_un ... xample.zip

The first example is a simple orange cube. The color is generated by a simple shader, profiled for DirectX (HLSL) and OpenGL (GLSL), and should work on Windows and Linux.
The second example is a textured cube, with an altered color. Texture is given by the shader (HLSL only by now).

EDIT: First example unified version (no more assembler)

Yup, no CG binding it seems.


On a Nvidia GF7 Series the simple shader doesent work.

Yes, the CG plugin isn't added in the Engine3D.dll for now.

Thanks !
The ASM Version works on ATI and NVidia. :D

I've modified the first example to use both HLSL (DirectX) and GLSL (OpenGL) profiles. It should work on Linux and Windows by now.

thanks. neat.

the first test worked fine. i was able to change the color by modifying the script.

the second one didn't work (just white). here's the ogre.log:

yup no real 2.0 shader support :P up to 1.4 works on thoose.

I'm running a GeForce 8400 GS which has no problems rendering Unreal Tournament 3. But I don't see any texture in the second example and, unless I'm missing something, I only see a solid (no lighting or shading) orange cube in the first example.

The orange cube uses the hlsl syntax for the shaders. The textured cube only uses the asm syntax. With the given code (the .cg files), you can recompile to another syntax with a tool like cgc.

I'm not supporting this anymore, as the new PB version is far more superior !
