This class can be used with raw OpenGL, without RenderDevice or SDL. If you use VertexProgramRef instead of VertexProgram*, the texture memory will be garbage collected. The vertex program must be written in the vertex program assembly languages specified by either: http://oss.sgi.com/projects/ogl-sample/registry/ARB/vertex_program.txt http://oss.sgi.com/projects/ogl-sample/registry/NV/vertex_program2.txt You can also write your programs in the NVIDIA Cg language and compile them with cgc to assembly language. You cannot load Cg programs directly with a VertexProgram. If an error is encountered inside a shader in debug mode, that error is printed to the debug window (under MSVC) and the programmer can fix the error and reload the shader without reloading the program. See G3D::GPUProgram for information on how constants and variable assignments generated by the Cg compiler are handled.

Returns false if it can't match the type. void G3D::GPUProgram::deletePrograms ( int  num, unsigned int *  id   ) const [protected, inherited] void G3D::GPUProgram::disable (  )  [inherited] Unbinds and disables. static VertexProgramRef G3D::VertexProgram::fromCode ( const std::string &  name, const std::string &  code   ) [static] static VertexProgramRef G3D::VertexProgram::fromFile ( const std::string &  filename  )  [static] void G3D::GPUProgram::genPrograms ( int  num, unsigned int *  id   ) const [protected, inherited] GLuint G3D::GPUProgram::getOpenGLID (  )  const [inherited] void G3D::GPUProgram::getProgramError ( int &  pos, const unsigned char *&  msg   ) const [protected, inherited] static GLenum G3D::GPUProgram::getUnitFromCode ( const std::string &  code, Extension &  extension   ) [static, protected, inherited] Determines which unit and extension API a shader uses from the first line. void G3D::GPUProgram::loadConstant ( int  slot, const Vector4 &  value   ) const [protected, inherited] void G3D::GPUProgram::loadProgram ( const std::string &  code  )  const [protected, inherited] void G3D::ReferenceCountedObject::ReferenceCountedObject_zeroWeakPointers (  )  [inline, inherited] Automatically called immediately before the object is deleted. This is not called from the destructor because it needs to be invoked before the subclass destructor. void G3D::GPUProgram::reload ( const std::string &  code = ""  )  [inherited] Reload from supplied code or from the original file that was specified (handy when debugging shaders). void G3D::GPUProgram::setArgs ( class RenderDevice *  , const ArgList &  args   ) [protected, inherited] Called by RenderDevice::setVertexProgram() and RenderDevice::setPixelProgram(). static std::string G3D::GPUProgram::toString ( const Type &  t  )  [static, inherited] Internal use only. For printing error messages.

Do not use or explicitly manipulate this value--its type may change in the future and is not part of the supported API. _WeakPtrLinkedList* G3D::ReferenceCountedObject::ReferenceCountedObject_weakPointer [inherited] Linked list of all weak pointers that reference this (some may be on the stack!). Do not use or explicitly manipulate this value.
