Member Function Documentation

virtual void GEO_Primitive::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 in GEO_PrimVolume, GEO_Hull, GEO_PrimParticle, GEO_VolumeElementBase, GEO_PrimTube, GEO_PrimSphere, GEO_PrimTriBezier, GEO_PrimCircle, and GEO_TriMesh.

virtual UT_Vector3 GEO_Primitive::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 in GEO_PrimVolume, GEO_PrimVDB, GEO_PrimPolySoup, GEO_Hull, GEO_PrimParticle, HDK_Sample::GEO_PrimTetra, GEO_VolumeElementBase, GEO_PrimPacked, GEO_Quadric, GEO_PrimCircle, GEO_PrimTriBezier, GEO_TriMesh, and GEO_PrimChannel.

		UT_Array< float > &	weightlist,
		fpreal	u,
		fpreal	v,
		fpreal	w
	)		const

virtual

Finds the weightings of the vertices that will compute an interior point given the u,v,w coordinates. The offsets are into the gdp's vertex list, not indices into this primitive's vertex list. Weights are normalized. Note this cannot be used to recover the Position as it often has special case logic (as in spheres, or rational splines), in those cases use evaluateInteriorPoint(UT_Vector4 &pos, ...) It has the advantage over the other evaluateInteriorPoints in that it allows you to avoid creating any temporary vertices. Behaviour for non-sublcassed types is to return the 0th vertex.

Reimplemented in GEO_PrimPolySoup, GEO_Curve, GEO_Face, GEO_PrimTetrahedron, GEO_PrimHexahedron, GEO_PrimTriBezier, GEO_Hull, GEO_TPSurf, and GEO_PrimPoly.

Enlarge a bounding box by the visible bounding box of the primitive.

A return value of false indicates an error in the operation, most likely an invalid P. By default, it merely calls enlargeBoundingBox()

virtual bool GEO_Primitive::getBBox ( UT_BoundingBox * bbox ) const

pure virtual

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.
