bool DXGraphicsStateGuardian9::begin_draw_primitives	(	const GeomPipelineReader *	geom_reader,
		const GeomMunger *	munger,
		const GeomVertexDataPipelineReader *	data_reader,
		bool	force
	)		`[virtual]`

Called before a sequence of draw_primitive() functions are called, this should prepare the vertex data for rendering.

It returns true if the vertices are ok, false to abort this group of primitives.

bool DXGraphicsStateGuardian9::begin_frame ( Thread * current_thread ) [virtual]

Called before each frame is rendered, to allow the GSG a chance to do any internal cleanup before beginning the frame.

The return value is true if successful (in which case the frame will be drawn and end_frame() will be called later), or false if unsuccessful (in which case nothing will be drawn and end_frame() will not be called).

Reimplemented from GraphicsStateGuardian.

Definition at line 1013 of file dxGraphicsStateGuardian9.cxx.

void DXGraphicsStateGuardian9::begin_occlusion_query ( ) [virtual]

Begins a new occlusion query.

After this call, you may call begin_draw_primitives() and draw_triangles()/draw_whatever() repeatedly. Eventually, you should call end_occlusion_query() before the end of the frame; that will return a new OcclusionQueryContext object that will tell you how many pixels represented by the bracketed geometry passed the depth test.

It is not valid to call begin_occlusion_query() between another begin_occlusion_query() .. end_occlusion_query() sequence.

Reimplemented from GraphicsStateGuardian.

Definition at line 738 of file dxGraphicsStateGuardian9.cxx.

bool DXGraphicsStateGuardian9::begin_scene ( ) [virtual]

Called between begin_frame() and end_frame() to mark the beginning of drawing commands for a "scene" (usually a particular DisplayRegion) within a frame.

All 3-D drawing commands, except the clear operation, must be enclosed within begin_scene() .. end_scene().

The return value is true if successful (in which case the scene will be drawn and end_scene() will be called later), or false if unsuccessful (in which case nothing will be drawn and end_scene() will not be called).

	)

This function is called after the creation of textures, vertex buffers, and index buffers to check if DirectX is out of memory.

Issues the DrawIndexedPrimitiveUP call to draw the indicated primitive_type from the given buffer.

As in draw_primitive_up(), above, the parameter list is not exactly one-for-one with the DrawIndexedPrimitiveUP() call, but it's similar (in particular, we pass max_index instead of NumVertices, which always seemed ambiguous to me).
