Member Function Documentation

const char* GusdCurvesWrapper::className ( ) const

Implements GT_Primitive.

UsdTimeCode  time,
GusdPurposeSet  purposes 
)

)
static
GT_PrimitiveHandle GusdCurvesWrapper::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 GusdCurvesWrapper::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 GusdCurvesWrapper::getMemoryUsage ( ) const
overridevirtual

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

Implements GT_Primitive.

int GusdCurvesWrapper::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 GusdCurvesWrapper::getUsdPrim ( ) const
inlineoverridevirtual

Implements GusdPrimWrapper.

Definition at line 50 of file curvesWrapper.h.

bool GusdCurvesWrapper::isValid ( ) const
overridevirtual

Return true if the underlying USD prim is valid.

Reimplemented from GusdPrimWrapper.

bool GusdCurvesWrapper::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 GusdCurvesWrapper::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 GusdCurvesWrapper::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.
