Member Function Documentation

void GEO_TriMesh::addToBSphere ( UT_BoundingSphere bsphere) const

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)
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.

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

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.

UT_Vector3D GEO_TriMesh::baryCenterD ( ) const

Reimplemented from GEO_Primitive.

static GA_PrimitiveFamilyMask GEO_TriMesh::buildFamilyMask ( )

Definition at line 188 of file GEO_TriMesh.h.

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

Reimplemented in GEO_Curve.

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

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()).

GA_DereferenceStatus GEO_TriMesh::dereferencePoint ( GA_Offset  point,
bool  dry_run = false 

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_TriMesh::dereferencePoints ( const GA_RangeMemberQuery pt_q,
bool  dry_run = false 

Implements GA_Primitive.

int GEO_TriMesh::detachPoints ( GA_PointGroup grp)

Implements GEO_Primitive.

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

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.

bool GEO_TriMesh::evaluatePointRefMap ( GA_Offset  result_vertex,
GA_AttributeRefMap hlist,
fpreal  u,
fpreal  v,
uint  du,
uint  dv

Implements GEO_Primitive.

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

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.

Definition at line 230 of file GEO_TriMesh.h.

GA_Size GEO_TriMesh::find ( GA_Offset  pt) const
GA_Size GEO_TriMesh::findVertex ( GA_Offset  vtx) const

return the index of a vertex within our vertex list

Definition at line 109 of file GEO_TriMesh.h.

bool GEO_TriMesh::getBBox ( UT_BoundingBox bbox) const

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.

Reimplemented in GEO_Curve, and GEO_Face.

virtual bool GEO_TriMesh::vertexApply ( bool(*)(GA_Offset vtx, void *)  apply,
void data = 0 
) const

Apply the function to each vertex of the primitive. Break when the function returns true. Return the value of the last function applied (false if never called).
