Detailed Description

A GLSL shader program.

To compile a shader, first attach source files to the object with AddVertexSource() and AddFragmentSource(), then compile and link the program with Compile(). If there are errors, use GetInfoLog() to retrieve the compilation log.

A Shader is a State. Shader::Disable will disable the programmable pipeline, and enable the fixed-function pipeline.

Member Function Documentation

void AddFragmentSource (  const std::string &  fileName  )  [inline]

Adds a fragment program source file to the list of files to be compiled.

void AddVertexSource (  const std::string &  fileName  )  [inline]

Adds a vertex program source file to the list of files to be compiled.

virtual bool Compile (   )  [virtual]

Compiles the fragment and vertex source files into a shader program. Returns true if the compilation and linking was successful.

virtual std::string GetInfoLog (   )  [virtual]

Returns the info log with the results of shader compilation.

virtual void Render (   )  [virtual]
