Detailed Description

Constructor & Destructor Documentation

GEO_PrimVolume::GEO_PrimVolume ( GEO_Detail d,
GA_Offset  offset = GA_INVALID_OFFSET 
)
protected

NOTE: The constructor should only be called from subclass constructors.

virtual GEO_PrimVolume::~GEO_PrimVolume ( )
protectedvirtual

NOTE: The destructor should only be called from subclass destructors.

Member Function Documentation

virtual void GEO_PrimVolume::addPointRefToGroup ( GA_PointGroup grp) const
virtual
virtual void GEO_PrimVolume::addToBSphere ( UT_BoundingSphere bsphere) const
virtual

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).

Reimplemented from GEO_Primitive.

static GA_PrimitiveDefinition::SharedDataLoader* GEO_PrimVolume::allocateSharedDataLoader ( )
static

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.

virtual UT_Vector3 GEO_PrimVolume::baryCenter ( ) const
virtual

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

Reimplemented from GEO_Primitive.

static GA_PrimitiveFamilyMask GEO_PrimVolume::buildFamilyMask ( )
inlinestaticprotected

Definition at line 672 of file GEO_PrimVolume.h.

virtual fpreal GEO_PrimVolume::calcArea ( ) const
virtual

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.

virtual fpreal GEO_PrimVolume::calcVolume ( const UT_Vector3 ) const
virtual

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,
const GEO_PrimVolumeXform indexxform 
) const
virtual UT_Vector3 GEO_PrimVolume::computeNormal ( ) const
virtual

Return a normal vector for the primitive.

Implements GEO_Primitive.

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

Reimplemented from GEO_Primitive.

virtual void GEO_PrimVolume::copyPrimitive ( const GEO_Primitive src)
virtual

Implements GEO_Primitive.

virtual void GEO_PrimVolume::copyUnwiredForMerge ( const GA_Primitive src,
const GA_MergeMap map 
)
virtual

Copy the specified primitive as part of the merge. The source primitive will be of the same type.

Since the vertex offsets will change for the merged geometry, the map should be used to lookup the new vertex offsets. For example

map.mapDestFromSource( GA_ATTRIB_VERTEX, source_vertex );
See Also
GA_MergeMap

Reimplemented from GA_Primitive.

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

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.

virtual bool GEO_PrimVolume::enlargeBoundingBox ( UT_BoundingRect b,

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.

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.

virtual bool GEO_PrimVolume::enlargeBoundingSphere ( UT_BoundingSphere b,

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.

virtual void GEO_PrimVolume::enlargePointBounds ( UT_BoundingBox box) const

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.

Computes the voxel diameter by taking a step in x, y, and z converting to world space and taking the length of that vector.

UT_VoxelArrayHandleF GEO_PrimVolume::getVoxelHandle ( ) const

Returns a handle to a voxel array containing our data. This is should be thought of a copy of the data - changing it will not change the underlying data, casting this to a write handle will write to the newly created handle, not the one stored in this volume.

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

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

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).
