Detailed Description
Ogre assumes that there are separate vertex and fragment programs to deal with but GLSL ES 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 ES Link Program Manager does the same. The GLSL ES 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.

Populate a list of uniforms based on GLSL ES source.
- Parameters
-
src Reference to the source code constantDefs The defs to populate (will not be cleared before adding, clear it yourself before calling this if that's what you want). filename The file name this came from, for logging errors.
◆ extractUniforms()

| ) |
Populate a list of uniforms based on a program object.
- Parameters
-
programObject Handle to the program object to query vertexConstantDefs Definition of the constants extracted from the vertex program, used to match up physical buffer indexes with program uniforms. May be null if there is no vertex program. fragmentConstantDefs Definition of the constants extracted from the fragment program, used to match up physical buffer indexes with program uniforms. May be null if there is no fragment program. list The list to populate (will not be cleared before adding, clear it yourself before calling this if that's what you want).
