Effect()

gf::Effect::Effect ( const char *  vertexShader, const char *  fragmentShader  )

inlineprotected

Load both the vertex and fragment shaders from source codes in memory.

This function loads both the vertex and the fragment shaders. If one of them fails to load, the shader is left empty (the valid shader is unloaded).

The source codes must be a valid shaders in GLSL language. GLSL is a C-like language dedicated to OpenGL shaders; you'll probably need to read a good documentation for it before writing your own shaders.

Parameters

vertexShader	String containing the source code of the vertex shader
fragmentShader	String containing the source code of the fragment shader
