Modern OpenGL relies heavily on GLSL shaders. They are needed for pretty much everything you draw. To ease the handling of shaders I’ve decided publish my shader-collection (well, part of it, for now) on github. The shaders are sorted by GLSL version (currently: version 1.5, webgl 1.0) and “purpose”. Their implementation is focused on readability, not speed. Hence, they can be optimized quite heavily and be combined as well. Anyway, here’s the link:

I’m planning on continuously adding shaders.

I’ve shared parts of my rendering library on github:

https://github.com/numb3r23/ScIll-library

here’s a feature list:

• OpenGL 3.2 core profile rendering
• cpp, compiles with gcc & VS 2010
• cmake project-file
• focus on Imagefilters via GLSL fragment-shader

Here’s a little code example on the usage:

using namespace SciIllLib;

CFilter fltFXAA = new CFilter();
fltFXAA->LoadFragmentShader("res/glsl/filter/FXAA.frag");

SFilterEngine::ReGenerateTexture(&m_rtScene, GL_FLOAT); SFilterEngine::ReGenerateTexture(&m_rtFinal, GL_FLOAT);

SFilterEngine::PreRender(m_rtScene);
... render as usual ...
SFilterEngine::PostRender();

SFilterEngine::Apply(fltFXAA, m_rtScene, m_rtFinal);
SFilterEngine::ToScreen(fltDisplay, m_rtFinal);

Of course it can do much more – load textures, load models, …
