Member Function Documentation

const char* GusdSphereWrapper::className ( ) const
overridevirtual

Implements GT_Primitive.

static GT_PrimitiveHandle GusdSphereWrapper::defineForRead ( const UsdGeomImageable sourcePrim,
UsdTimeCode  time,
GusdPurposeSet  purposes 
)
static
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.
