Detailed Description

Represents a shader program.

One shader program contains a vertex, a geometry and a fragment shader. File endings: *.vert for vertex shader, *.frag for fragment shader and *.geom for geometry shader. The shader files have to be in the sub folder "Shaders", relative to this file.

Constructor & Destructor Documentation

Shader::Shader

(

const string &

path

)

Loads shaders from files and compiles them.

When path is "hello", the files "hello.frag" & "hello.vert" will be loaded.

Definition at line 8 of file Shader.cpp.

Member Function Documentation

Shader::operator bool ( )

inline

A little cast helper.

With this you can simply do "if (shader) {...}" to test if a shader has been compiled successfully.
