Detailed Description

A Shader object represents one GLSL program.

One object can store either the standard rendering pipeline shaders (vertex, geometry, fragment...) or a group of compute shaders. For convenience, it also stores a user defined name, making it easier to access the shaders from within the main program. The shader's name is the same as the shaders filenames, without the extensions.
