Member Function Documentation

void GEO_PrimVolume::addToBSphere ( UT_BoundingSphere *  bsphere) const
overridevirtual

Enlarge the bounding sphere with the primitive's bounds. By default, this will enlarge the bounding sphere by the primitive's bounding box (i.e. getBBox()). It may be possible to have a tighter bound (i.e. the vertex hull for many primitives is a much better metric).

Methods to save/load shared voxel data

void GEO_PrimVolume::assignVertex ( GA_Offset  new_vtx,
bool  update_topology

This method assigns a preallocated vertex to the quadric, optionally creating the topological link between the primitive and new vertex.

UT_Vector3 GEO_PrimVolume::baryCenter ( ) const
overridevirtual

For a volume the barycenter is the same as the point.

fpreal GEO_PrimVolume::calcArea ( ) const

If the method isn't known, or doesn't make sense, we return 0.

Reimplemented from GEO_Primitive.

fpreal GEO_PrimVolume::calcAverage ( ) const
fpreal GEO_PrimVolume::calcMaximum ( ) const
fpreal GEO_PrimVolume::calcMinimum ( ) const

Compute useful aggregate properties of the volume.

fpreal GEO_PrimVolume::calcPositiveDensity ( ) const

Computes the total density of the volume, scaled by the volume's size. Negative values will be ignored.

fpreal GEO_PrimVolume::calcVolume ( const UT_Vector3 &  ) const
overridevirtual

If the method isn't known, or doesn't make sense, we return 0.

Reimplemented from GEO_Primitive.

virtual void GEO_PrimVolume::clearForDeletion ( )
protectedvirtual

Private interface The clearForDeletion() method is called just prior to the detail being cleared out. This allows the primitive to simplify its data structures, knowing that topology doesn't need to be maintained (i.e. unwiring all vertices);

Reimplemented from GA_Primitive.

bool GEO_PrimVolume::computeHeightFieldProperties ( int &  a1,
int &  a2,
int &  axis,
fpreal &  scale 
) const

Determine our orientation if we are to be considered a heightfield. Returns false if we shouldn't be treated as a heightfield.

bool GEO_PrimVolume::computeHeightFieldProperties ( int &  a1,
int &  a2,
int &  axis,
fpreal &  scale,
const UT_VoxelArrayF &  vox,

UT_Vector3 GEO_PrimVolume::computeNormal ( ) const

Return a normal vector for the primitive.

Implements GEO_Primitive.

UT_Vector3D GEO_PrimVolume::computeNormalD ( ) const

Implements GEO_Primitive.

GEO_Primitive* GEO_PrimVolume::copy ( int  preserve_shared_pts = 0) const
overridevirtual

Reimplemented from GEO_Primitive.

void GEO_PrimVolume::copyPrimitive ( const GEO_Primitive *  src)
overridevirtual

Implements GEO_Primitive.

void GEO_PrimVolume::copySubclassData ( const GA_Primitive *  source)
overridevirtual

Copy all subclass data from source to this.

The vertex lists of source and this must already be equivalent in some manner, though possibly referring to different vertices.

If some subclass data is dependent on the vertex list contents, (such as GEO_PrimPolySoup::myPolygonVertexList), it should be mapped based on the correspondence between the two. GEO_PrimPolySoup is currently the only primitive type with this sort of dependence, so it's probably best not to add more.

NOTE: This must be safe to call on different primitives in parallel at the same time.

Reimplemented from GA_Primitive.

GA_DereferenceStatus GEO_PrimVolume::dereferencePoint ( GA_Offset  point,
bool  dry_run = false 
)
overridevirtual

Before a point is deleted, all primitives using the point will be notified. The method should return "false" if it's impossible to delete the point. Otherwise, the vertices should be removed.

Implements GA_Primitive.

GA_DereferenceStatus GEO_PrimVolume::dereferencePoints ( const GA_RangeMemberQuery &  pt_q,

void GEO_PrimVolume::dispatchToReadHandle ( OP &  op) const

This function calls operator() on op with a COW read handle to this volume's actual voxel array handle. operator() must be templated to support different handles: template <typename t>=""> void operator()(const UT_COWReadHandle<UT_VoxelArray<T>>&);

template<typename OP >
void GEO_PrimVolume::dispatchToWriteHandle ( OP &  op,
bool  force_load 
)

This function calls operator() on op with a COW write handle to this volume's actual voxel array handle. operator() must be templated to support different handles: template <typename t>=""> void operator()(const UT_COWWriteHandle<UT_VoxelArray<T>>&); If force_load is true, voxel data is first fully loaded; otherwise, the handle is used as is.

bool GEO_PrimVolume::enlargeBoundingBox ( UT_BoundingRect &  b,
const GA_Attribute *  P 
) const
overridevirtual

Enlarge a bounding box by the bounding box of the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position these methods simply enlarge the bounding box based on the vertex.

Reimplemented from GEO_Primitive.

bool GEO_PrimVolume::enlargeBoundingBox ( UT_BoundingBox &  b,
const GA_Attribute *  P 
) const
overridevirtual

Enlarge a bounding box by the bounding box of the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position these methods simply enlarge the bounding box based on the vertex.

Reimplemented from GEO_Primitive.

bool GEO_PrimVolume::enlargeBoundingSphere ( UT_BoundingSphere &  b,
const GA_Attribute *  P 
) const
overridevirtual

Enlarge a bounding sphere to encompass the primitive. A return value of false indicates an error in the operation, most likely an invalid P. For any attribute other than the position this method simply enlarges the sphere based on the vertex.

Reimplemented from GA_Primitive.

void GEO_PrimVolume::enlargePointBounds ( UT_BoundingBox &  box) const
overridevirtual

Enlarge a point bounding box for implicit primitive bounds. If a primitive (such as a sphere) has a bounding box larger than its point hull, then it should implement this method. Otherwise, it can rely on the default behaviour.

NOTE: If you make a custom primitive type whose bounding box may be larger than the bounding box of the points referenced by vertices of the primitive, you must override this function in order for the detail's bounding box to be correctly computed. It does not suffice to override GEO_Primitive::getBBox(), since GA_Detail::computeQuickBounds will find the point bounding box of the entire detail, and then call enlargePointBounds on all primitives except polygons, tetrahedra, polysoups, and other primitive types that are known in advance to not exceed their point bounding boxes.

Reimplemented from GA_Primitive.

bool GEO_PrimVolume::evaluateBaryCenterRefMap ( GA_Offset  result_vtx,
GA_AttributeRefMap &  map

By default, this will call evaluateInteriorPointRefMap with u=.5 and v=.5. This is likely not the perfect solution. At the current time, this is only used in POPs to birth points at primitive centers.

Converts from 0..1 voxel space to world space.

bool GEO_PrimVolume::getBBox ( UT_BoundingBox *  bbox) const
overridevirtual

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation). This function should always initialize bbox, even if returning false, in which case, the bbox->isValid() may be false, representing an empty bounding box. This function should also not use any initial value of bbox, so it does not need to be initialized beforehand.

By passing in a specific read handle, we can accelerate.

bool GEO_PrimVolume::isInside ( UT_Vector3  pos) const

Returns true if the given point is entirely inside the volume's definition, ie, if posToIndex would return true.

bool GEO_PrimVolume::isInsideStrict ( UT_Vector3  pos) const

Returns true only if strictly inside. This means only actual voxel samples will be used for interpolation, so the boundary conditions will be unused

template<typename T >
bool GEO_PrimVolume::isInsideStrict ( const UT_Vector3 &  opos,
const UT_COWReadHandle< UT_VoxelArray< T >> &  vox 
) const

By passing in a specific read handle, we can accelerate isInsideStrict()

bool GEO_PrimVolume::isSDF ( ) const

void GEO_PrimVolume::stashed ( bool  beingstashed,
GA_Offset  offset = GA_INVALID_OFFSET 
)
overridevirtual

Stash (deactivate) or unstash (reactivate) the primitive.

Stashing a primitive will set its offset to that specified, typically GA_INVALID_OFFSET. Primitives are only stashed as part of clearing a detail, so there is no need to explicitly deallocate vertices. It is safe to delete a stashed primitive.

Unstashing a primitive will re-register that primitive with its parent detail at the specified offset (or a new offset if GA_INVALID_OFFSET).
