GT_PrimitiveHandle GusdNURBSCurvesWrapper::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 GusdNURBSCurvesWrapper::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 GusdNURBSCurvesWrapper::getMemoryUsage ( ) const

overridevirtual

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

Implements GT_Primitive.

int GusdNURBSCurvesWrapper::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 GusdNURBSCurvesWrapper::getUsdPrim ( ) const

inlineoverridevirtual

Implements GusdPrimWrapper.

Definition at line 50 of file NURBSCurvesWrapper.h.

bool GusdNURBSCurvesWrapper::isValid ( ) const

overridevirtual

Return true if the underlying USD prim is valid.

Reimplemented from GusdPrimWrapper.

bool GusdNURBSCurvesWrapper::redefine	(	const UsdStagePtr &	stage,
		const SdfPath &	path,
		const GusdContext &	ctxt,
		const GT_PrimitiveHandle &	sourcePrim
	)

overridevirtual

Create a new USD prim to match GT primitive.

When writing per frame USD files, we need to recreate the stage and all the primitives on it each frame. However, there is some data we want to persist across frames. So we keep the GusdPrimWrappers and ask them to redefine their USD prims on each frame.

Reimplemented from GusdPrimWrapper.

bool GusdNURBSCurvesWrapper::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.

bool GusdNURBSCurvesWrapper::updateFromGTPrim	(	const GT_PrimitiveHandle &	sourcePrim,
		const UT_Matrix4D &	houXform,
		const GusdContext &	ctxt,
		GusdSimpleXformCache &	xformCache
	)

overridevirtual

Fill a USD prim's attribute samples for a frame from the attributes in a GT primitive.

If sourcePrim is an instance, localXform is the instance transform otherwise it is the primitive transform from the prim.

Reimplemented from GusdPrimWrapper.
