Member Function Documentation

void GEO_TriMesh::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).

Reimplemented from GEO_Primitive.

virtual GA_Size GEO_TriMesh::appendVertex ( GA_Offset ppt )

virtual

Reimplemented in GEO_PrimPolySoup, GEO_PrimNURBCurve, GEO_PrimRBezCurve, and GEO_PrimPoly.

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_existing	If set, existing vertex offsets are destroyed.
update_topology	If set, new vertices are wired to the primitive.

UT_Vector3 GEO_TriMesh::baryCenter ( ) const

overridevirtual

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.

virtual

Reimplemented in GEO_PrimNURBCurve, GEO_PrimRBezCurve, and GEO_PrimPoly.

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()).

GA_DereferenceStatus GEO_TriMesh::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_TriMesh::dereferencePoints	(	const GA_RangeMemberQuery &	pt_q,

bool GEO_TriMesh::evaluateBaryCenterRefMap	(	GA_Offset	result_vtx,

overrideprotectedvirtual

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.

		float	v = `0`,
		unsigned	du = `0`,

	)		const

inlineoverrideprotectedvirtual

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

inline

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

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.

Implements GEO_Primitive.

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

vtx	Vertex 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.

Reimplemented in GEO_PrimPoly.

Warning: swapVertices() doesn't check the bounds, nor that j != i. Use with caution.
