GT_PrimitiveHandle GusdSphereWrapper::doSoftCopy ( ) const

overridevirtual

Create a copy of the primitive, referencing all the source data This can return a NULL pointer, but it would be better to implement it properly.

Implements GT_Primitive.

void GusdSphereWrapper::enlargeBounds	(	UT_BoundingBox	boxes[],
		int	nsegments
	)		const

overridevirtual

An array of bounding boxes is passed in. There is a bounding box for each segement. Each bounding box should be enlarged appropriately.

Implements GT_Primitive.

int64 GusdSphereWrapper::getMemoryUsage ( ) const

overridevirtual

Return an approximate memory usage. Since data may be shared, this will always be an over-estimation.

Implements GT_Primitive.

int GusdSphereWrapper::getMotionSegments ( ) const

overridevirtual

Return the number of motion segments defined on the geometry By default, this simply returns the number of segments on P.

Implements GT_Primitive.

const UsdGeomImageable GusdSphereWrapper::getUsdPrim ( ) const

inlineoverridevirtual

Implements GusdPrimWrapper.

Definition at line 27 of file sphereWrapper.h.

bool GusdSphereWrapper::isValid ( ) const

overridevirtual

Return true if the underlying USD prim is valid.

Reimplemented from GusdPrimWrapper.

bool GusdSphereWrapper::refine	(	GT_Refine &	refiner,
		const GT_RefineParms *	parms = `NULL`
	)		const

overridevirtual

Refine the primitive.

refiner
The refiner object is responsible for processing primitives, and also giving the primitive hints on how to refine itself. The method should returns true if new primitives were added to the refiner.

Reimplemented from GT_Primitive.
