const GEO_Primitive prim 
GT_PrimVDB::~GT_PrimVDB ( )

Member Function Documentation

const char* GT_PrimVDB::className ( ) const

Implements GT_Primitive.

Definition at line 34 of file GT_PrimVDB.h.

GT_PrimitiveHandle GT_PrimVDB::doSoftCopy ( ) const

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.

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

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 GU_ConstDetailHandle& GT_PrimVDB::getDetail ( ) const

Definition at line 91 of file GT_PrimVDB.h.

const GEO_PrimVDB* GT_PrimVDB::getGeoPrimitive ( ) const

Definition at line 90 of file GT_PrimVDB.h.

SYS_FORCE_INLINE const openvdb::GridBase* GT_PrimVDB::getGrid ( )

Definition at line 88 of file GT_PrimVDB.h.

GT_TransformHandle GT_PrimVDB::getGridTransform ( )
exint GT_PrimVDB::getLeafCoords ( UT_Vector3FArray coords,
UT_Int16Array masks 
) const
int64 GT_PrimVDB::getMemoryUsage ( ) const

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

Implements GT_Primitive.

Definition at line 64 of file GT_PrimVDB.h.

int GT_PrimVDB::getMotionSegments ( ) const

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 63 of file GT_PrimVDB.h.

GA_Offset GT_PrimVDB::getPointOffset ( ) const

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

Definition at line 74 of file GT_PrimVDB.h.

GA_Offset GT_PrimVDB::getPrimitiveOffset ( ) const

Definition at line 72 of file GT_PrimVDB.h.

int GT_PrimVDB::getPrimitiveType ( ) const

Return the primitive type. By default this returns GT_PRIM_UNDEFINED,

Reimplemented from GT_Primitive.

Definition at line 31 of file GT_PrimVDB.h.

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

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 84 of file GT_PrimVDB.h.

GEO_PrimVolumeXform GT_PrimVDB::getVolumeIndexTransform ( ) const
GEO_PrimVolumeXform GT_PrimVDB::getVolumeTransform ( ) const
bool GT_PrimVDB::isInvisible ( ) const

Definition at line 38 of file GT_PrimVDB.h.

bool GT_PrimVDB::isLevelSet ( ) const

Definition at line 36 of file GT_PrimVDB.h.

bool GT_PrimVDB::isVolume ( ) const

Definition at line 37 of file GT_PrimVDB.h.

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

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.

void GT_PrimVDB::setUniformAttributes ( const GT_AttributeListHandle uniform)

Set the list of uniform attributes.

Definition at line 79 of file GT_PrimVDB.h.

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

update any cached data for geometry and its attributes

Reimplemented from GT_Primitive.

const GT_ViewportRefineOptions& GT_PrimVDB::viewportRefineOptions ( ) const

Viewport refinement options – changes on LOD.

Reimplemented from GT_Primitive.
