inlinestatic

Store a VDB grid in a new VDB primitive and add the primitive to a geometry detail.

Parameters

gdp	the detail to which to add the new primitive
grid	a grid to be associated with the new primitive
src	if non-null, copy attributes and groups from this primitive
name	if non-null, set the new primitive's `name` attribute to this string; otherwise, if src is non-null, use its name

void GU_PrimVDB::countMemory ( UT_MemoryCounter & counter ) const

overridevirtual

Count memory usage using a UT_MemoryCounter in order to count shared memory correctly. NOTE: This should always include sizeof(*this).

Reimplemented from GA_Primitive.

static SYS_FORCE_INLINE void GU_PrimVDB::createAttrsFromMetadata	(	GA_AttributeOwner	owner,
		GA_Offset	element,

Parameters

owner	the type of element
element	the offset of the element
meta_map	the metadata that should be transferred
gdp	the detail to which to transfer attributes
