Function Documentation

void GIAPIENTRY giGLRenderParameterb	(	GIenum	pname,
		GIboolean	param
	)

Set boolean render parameter.

Parameters:

pname	state to set
param	value to set

void GIAPIENTRY giGLRenderParameteri	(	GIenum	pname,
		GIint	param
	)

Set integer render parameter.

Parameters:

pname	state to set
param	value to set

void GIAPIENTRY giGLAttribRenderParameteri	(	GIuint	attrib,
		GIenum	pname,
		GIint	param
	)

Set integer attribute render parameter.

Parameters:

attrib	attribute channel
pname	state to set
param	value to set

void GIAPIENTRY giGLDrawMesh

(

)

Render current mesh immediately.

This function renders the current bound mesh by glBegin()/glEnd() using the current OpenGL context. It should be built into a display list when needed more than once.

void GIAPIENTRY giGLDrawCut

(

)

Render current cut of current mesh immediately.

This function renders the current cut of the current bound mesh as lines by glBegin()/glEnd() using the current OpenGL context. It should be built into a display list when needed more than once.

void GIAPIENTRY giGLDrawGIM

(

)

Draw Geometry Images as triangular mesh.

This function renders the attributes currently bound images a a triangular mesh.

void GIAPIENTRY giGLCleanUp

(

)

Clean up OpenGL context specific data.

This function should be called before the GL context used by OpenGI is destroyed or changes during the lifetime of the active OpenGI context, as OpenGI may create GL context local data as e.g. shaders. It need not be called when the GI context is destroyed before the GL context, but it has to be called between calls to giSample() or giGLDraw[Mesh/Cut/GIM]() within different GL contexts.
