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

Member Function Documentation

virtual void GEO_TriMesh::addPointRefToGroup ( GA_PointGroup grp) const
finalvirtual
virtual void GEO_TriMesh::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.

virtual GA_Size GEO_TriMesh::appendVertex ( GA_Offset  ppt)
virtual
void GEO_TriMesh::assignVertexList ( const GA_OffsetList list,
bool  destroy_existing = true,
bool  update_topology = true 
)

Replaces the entire vertex list. Use with utmost caution. It probably won't work with Nurbs or Polysoups, and possibly other primitives and is only tested for Polygons.

Parameters
destroy_existingIf set, existing vertex offsets are destroyed.
update_topologyIf set, new vertices are wired to the primitive.
virtual UT_Vector3 GEO_TriMesh::baryCenter ( ) const
virtual

Return the center of the primitive. This defaults to the center of the bounding box. A better approximation might be the average value of the vertex positions (which could be different).

Reimplemented from GEO_Primitive.

Reimplemented in GEO_PrimPolySoup.

virtual bool GEO_TriMesh::changePointRef ( GA_Offset  from,
GA_Offset  to 
)
virtual

Reimplemented in GEO_Curve.

virtual void GEO_TriMesh::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.

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

Reimplemented from GEO_Primitive.

Reimplemented in GEO_PrimPolySoup, GEO_Face, and GEO_Curve.

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

Implements GEO_Primitive.

Reimplemented in GEO_PrimPolySoup, GEO_Face, and GEO_Curve.

virtual void GEO_TriMesh::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 );

GA_MergeMap

Reimplemented from GA_Primitive.

Reimplemented in GEO_PrimPolySoup, GEO_Face, and GEO_Curve.

void GEO_TriMesh::countBaseMemory ( UT_MemoryCounter counter) const

This is called by the subclasses to count the memory used by myVertexList

virtual int GEO_TriMesh::deleteVertex ( GA_Size  num)
virtual
virtual void GEO_TriMesh::deleteVertices ( const UT_Array< GA_Size > &  nums)
virtual

Remove all vertices listed in the array. The array must be in order, contain no duplicates, and all numbers must be in the range [0, getVertexCount()).

virtual GA_DereferenceStatus GEO_TriMesh::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

Implements GEO_Primitive.

virtual bool GEO_TriMesh::evaluateBaryCenterRefMap ( GA_Offset  result_vtx,
GA_AttributeRefMap map 
) const
protectedvirtual

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.

Reimplemented from GEO_Primitive.

virtual int GEO_TriMesh::evaluatePointV4 ( UT_Vector4 pos,
float  u,
float  v = 0,
unsigned  du = 0,
unsigned  dv = 0 
) const
inlineprotectedvirtual

Evaluate the position for the given parametric coordinates (with the given derivatives). Return 0 if successful, or -1 if failure. The default implementation returns {0,0,0,0};

Reimplemented from GEO_Primitive.

Reimplemented in GEO_Curve, and GEO_Face.

Compute the bounding box of the primitive. Return 0 if unable to compute bounds (1 on successful computation)

Is the primitive degenerate.

Implements GA_Primitive.

Reimplemented in GEO_Curve, GEO_PrimPoly, GEO_Face, GEO_PrimTriFan, and GEO_PrimTriStrip.

bool GEO_TriMesh::isPointListTrivial ( ) const

A trivial point list is doubly-trivial: getPointOffset(i) == getPointOffset(0) + i This requires testing every point so is slower than isVertexListTrivial.

bool GEO_TriMesh::isVertexListTrivial ( ) const
inline

A trivial vertex list is a uniform ascending list, so getFastVertexOffset(i) == getFastVertexOffset(0) + i

Release the vertex vtx, i.e. deletes it from myVertexList but doesn't delete the offset itself. Consequently, topology information and attributes are preserved. It's meant to be used by stealVertex

virtual void GEO_TriMesh::stashed ( bool  beingstashed,
GA_Offset  offset = GA_INVALID_OFFSET 
)
virtual

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).

Reimplemented from GA_Primitive.

Reimplemented in GEO_PrimPolySoup.

virtual GA_Size GEO_TriMesh::stealVertex ( GA_Offset  vtx,
GA_Offset  insert_before_vtx = GA_INVALID_OFFSET 
)
virtual

Steal a vertex from its current primitive and insert it into our vertex list.

Parameters
vtxVertex to be stolen
insert_before_vtx(Optional) the vertex before which to insert the stolen vertex If unspecified (negative) or if the vertex doesn't exist, the stolen vertex is appended at the end of the vertex list.
Returns
The position at which vtx is inserted if successful, or -1 otherwise.
