Detailed Description

Refine primitives for a detail.

When a detail refines itself, it asks the "collectors" to refine primitives. The refiners can "collect" primitives on the fly, or they can collect primitives and generate a single primitive at the end of the collection.

Examples:: packedsphere/GT_GEOPackedSphere.h, and tetprim/GT_PrimTetra.h.

virtual GT_GEOPrimCollectData* GT_GEOPrimCollect::beginCollecting	(	const GT_GEODetailListHandle &	geometry,

	)		const

virtual

This method is called when the detail begins collecting. The method may or may not be called if there are now collectable primitives in the detail.

The data container is passed to the collect() and endCollect() methods. It is automatically deleted on completion. If no data is needed for collection, this method should return a NULL pointer (which is the default behaviour).

Reimplemented in GT_GEOPrimCollectVolume, GusdGT_PrimCollect, GABC_NAMESPACE::GABC_CollectPacked, GT_GEOPrimCollectChannel, HDK_Sample::GT_PrimTetraCollect, and GT_GEOPrimCollectPacked.

void GT_GEOPrimCollect::bind ( const GA_PrimitiveTypeId & id ) const

Register to process primitives of the given primitive id. You can bind to multiple primitive types, in which case, beginCollecting() and endCollecting() will be invoked only once for each detail traversal. collect() will be called for each primitive that matches any of the bound primitive types. For example:

gt_GEOPrimQuadricCollect  *q = new gt_GEOPrimQuadricCollect();
q->bind(GA_PrimitiveType(GA_PRIMCIRCLE));
q->bind(GA_PrimitiveType(GA_PRIMSPHERE));
q->bind(GA_PrimitiveType(GA_PRIMTUBE));

virtual GT_PrimitiveHandle GT_GEOPrimCollect::collect	(	const GT_GEODetailListHandle &	geometry,
		const GEO_Primitive const	prim_list,
		int	nsegments,
		GT_GEOPrimCollectData *	data
	)		const

pure virtual

For each matching primitive in the detail, this method will be called. If no GT primitive should be created, return an empty handle.

Implemented in GT_GEOPrimCollectVolume, GusdGT_PrimCollect, GT_GEOPrimCollectVDB, GABC_NAMESPACE::GABC_CollectPacked, GT_GEOPrimCollectChannel, HDK_Sample::GT_PrimTetraCollect, and GT_GEOPrimCollectPacked.

virtual GT_PrimitiveHandle GT_GEOPrimCollect::endCollecting	(	const GT_GEODetailListHandle &	geometry,
		GT_GEOPrimCollectData *	data
	)		const

virtual

Complete any processing fter all primitives have been collected

This method should not delete the collection data

Reimplemented in GT_GEOPrimCollectVolume, GusdGT_PrimCollect, GABC_NAMESPACE::GABC_CollectPacked, GT_GEOPrimCollectChannel, HDK_Sample::GT_PrimTetraCollect, and GT_GEOPrimCollectPacked.

static GT_GEOPrimCollectPtr GT_GEOPrimCollect::getCollector ( const GA_PrimitiveTypeId & id )

static

Get the current collector bound for a primitive.
