Detailed Description

Ogre assumes that there are separate vertex and fragment programs to deal with but GLSL has one program object that represents the active vertex and fragment shader objects during a rendering state.

GLSL Vertex and fragment shader objects are compiled separately and then attached to a program object and then the program object is linked. Since Ogre can only handle one vertex program and one fragment program being active in a pass, the GLSL Link Program Manager does the same. The GLSL Link program manager acts as a state machine and activates a program object based on the active vertex and fragment program. Previously created program objects are stored along with a unique key in a hash_map for quick retrieval the next time the program object is required.
