inlineoverridevirtual

For primitives that may need updating if the GL state changes, this hook allows you to perform a check if no update is otherwise required. Return true to have checkGLState() called. Returning true from that will trigger an update.

Reimplemented from GR_Primitive.

Definition at line 317 of file GR_PrimPacked.h.

Definition at line 37 of file GR_PrimPacked.h.

void GR_PrimPacked::cleanup ( RE_RenderContext r )

inlineoverridevirtual

called once per viewport draw, setup() before any renders are done, and cleanup() after all are complete. There is a possibility that render() may not be called at all.

GR_Primitive::GR_DispOptChange GR_PrimPacked::displayOptionChange	(	const GR_DisplayOption &	opts,

inlineoverridevirtual

Called when the geometry-related display options change, to determine if an update is required. By default, no update is required. If the options did change, return either DISPLAY_CHANGED, which will call update() without bumping the display option version, or DISPLAY_VERSION_CHANGED, which will bump the version. If 'first_init' is true, this is being called to initialize any cached display options. The return value will be ignored. This will happen just after the primitive is created.

Find the vertex offset for a given vertex id. The integer returned corresponds with the GA_Offset for the given vertex. If the vertex_id is invalid, the method will return -1.

void GR_PrimPacked::update	(	RE_RenderContext	r,
		const GT_PrimitiveHandle &	primh,
		const GR_UpdateParms &	p
	)

overridevirtual

Main update method, called when conditions change which may require the geometry to be updated. These include geometry changes, selections, volatile display options (level of detail), instancing updates, and some GL state changes (if needsGLStateCheck returns true)

Implements GR_Primitive.
