Member Function Documentation

virtual const char* GT_PrimVDB::className ( void  ) const
inlinevirtual

Implements GT_Primitive.

Definition at line 36 of file GT_PrimVDB.h.

virtual GT_PrimitiveHandle GT_PrimVDB::doSoftCopy ( ) const
inlinevirtual

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.

Definition at line 66 of file GT_PrimVDB.h.

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

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.

const GEO_PrimVDB* GT_PrimVDB::getGeoPrimitive ( ) const
inline

Definition at line 82 of file GT_PrimVDB.h.

const openvdb::GridBase* GT_PrimVDB::getGrid ( )
GT_TransformHandle GT_PrimVDB::getGridTransform ( )
exint GT_PrimVDB::getLeafCoords ( UT_Vector3FArray coords,
UT_Int16Array masks 
) const
virtual int64 GT_PrimVDB::getMemoryUsage ( ) const
inlinevirtual

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

Implements GT_Primitive.

Definition at line 65 of file GT_PrimVDB.h.

virtual int GT_PrimVDB::getMotionSegments ( ) const
inlinevirtual

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

Implements GT_Primitive.

Definition at line 64 of file GT_PrimVDB.h.

GA_Offset GT_PrimVDB::getPointOffset ( ) const
inline

Definition at line 73 of file GT_PrimVDB.h.

GT_PrimitiveHandle GT_PrimVDB::getPointPrimitive ( ) const

Returns a GT_PrimPointMesh with 1 point containing the VDB's 1 point. Contains all of the VDBs attributes as point or uniform attributes.

UT_Vector3F GT_PrimVDB::getPrimColor ( ) const
inline

Definition at line 74 of file GT_PrimVDB.h.

GA_Offset GT_PrimVDB::getPrimitiveOffset ( ) const
inline

Definition at line 72 of file GT_PrimVDB.h.

virtual int GT_PrimVDB::getPrimitiveType ( ) const
inlinevirtual

Return the primitive type. By default this returns GT_PRIM_UNDEFINED,

Reimplemented from GT_Primitive.

Definition at line 34 of file GT_PrimVDB.h.

UT_Vector3I GT_PrimVDB::getRes ( ) const
virtual const GT_AttributeListHandle& GT_PrimVDB::getUniformAttributes ( ) const
inlinevirtual

Virtual methods to access the attribute data for primitives Some primitives may not implement these methods, in which case, the returned value will be an empty list.

Reimplemented from GT_Primitive.

Definition at line 78 of file GT_PrimVDB.h.

GEO_PrimVolumeXform GT_PrimVDB::getVolumeIndexTransform ( ) const
GEO_PrimVolumeXform GT_PrimVDB::getVolumeTransform ( ) const
bool GT_PrimVDB::isLevelSet ( ) const
inline

Definition at line 38 of file GT_PrimVDB.h.

bool GT_PrimVDB::isVolume ( ) const
inline

Definition at line 39 of file GT_PrimVDB.h.

virtual bool GT_PrimVDB::refine ( GT_Refine refiner,
const GT_RefineParms parms = NULL 
) const
virtual

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.

virtual bool GT_PrimVDB::updateGeoPrim ( const GU_ConstDetailHandle dtl,
const GT_RefineParms parms 
)
virtual

update any cached data for geometry and its attributes

Reimplemented from GT_Primitive.

virtual const GT_ViewportRefineOptions& GT_PrimVDB::viewportRefineOptions ( ) const
virtual

Viewport refinement options – changes on LOD.

Reimplemented from GT_Primitive.
