The ShaderGenerator is a device that effectively replaces the classic fixed function pipeline with a 'next-gen' fixed function pipeline.
The next-gen fixed function pipeline supports features like normal mapping, gloss mapping, cartoon lighting, and so forth. It works by automatically generating a shader from a given RenderState.
Currently, there is one ShaderGenerator object per GraphicsStateGuardian. It is our intent that in time, people will write classes that derive from ShaderGenerator but which yield slightly different results.
The ShaderGenerator owes its existence to the 'Bamboo Team' at Carnegie Mellon's Entertainment Technology Center. This is a group of students who, as a semester project, decided that next-gen graphics should be accessible to everyone, even if they don't know shader programming. The group consisted of:
Aaron Lo, Programmer Heegun Lee, Programmer Erin Fernandez, Artist/Tester Joe Grubb, Artist/Tester Ivan Ortega, Technical Artist/Tester
Thanks to them!
ShaderGenerator | ( | GraphicsStateGuardianBase | gsg, |
GraphicsOutputBase | host | ||
) |
Create a ShaderGenerator.
This has no state, except possibly to cache certain results. The parameter that must be passed is the GSG to which the shader generator belongs.
static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from TypedObject.
TypeHandle getType | ( | ) | [inherited] |
Reimplemented in AnimChannelBase.
int getTypeIndex | ( | ) | [inherited] |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.
This is equivalent to get_type().get_index().
bool isExactType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is the indicated type exactly.
bool isOfType | ( | TypeHandle | handle | ) | [inherited] |
Returns true if the current object is or derives from the indicated type.
RenderAttrib const synthesizeShader | ( | RenderState const | rs | ) |
This is the routine that implements the next-gen fixed function pipeline by synthesizing a shader.
It also takes care of setting up any buffers needed to produce the requested effects.
