A GT_Primitive that wraps a USD Prim.
Definition: primWrapper.h:89
Points are analogous to the RiPoints spec.

virtual bool updateFromGTPrim(const GT_PrimitiveHandle &sourcePrim, const UT_Matrix4D &houXform, const GusdContext &ctxt, GusdSimpleXformCache &xformCache)
Fill a USD prim's attribute samples for a frame from the attributes in a GT primitive.
virtual bool redefine(const UsdStagePtr &stage, const SdfPath &path, const GusdContext &ctxt, const GT_PrimitiveHandle &sourcePrim)
Create a new USD prim to match GT primitive.
Represent a time value, which may be either numeric, holding a double value, or a sentinel value UsdT...
Definition: timeCode.h:85
static GT_PrimitiveHandle defineForWrite(const GT_PrimitiveHandle &sourcePrim, const UsdStagePtr &stage, const SdfPath &path, const GusdContext &ctxt)
Given a GT_Primitive, create a USD prim of the proper type.
A GusdContext structure is created by the ROPs that write USD files and passed to the GusdPrimWrapper...
Definition: context.h:46
A path value used to locate objects in layers or scenegraphs.
Definition: path.h:287
virtual bool isValid() const
Return true if the underlying USD prim is valid.
static GT_PrimitiveHandle defineForRead(const UsdGeomImageable &sourcePrim, UsdTimeCode time, GusdPurposeSet purposes)
Given a USD prim, create a GusdPrimWrapper of the proper type.
Base class for all prims that may require rendering or visualization of some sort.
