Member Function Documentation

virtual void GEO_Primitive::addPointRefToGroup ( GA_PointGroup & grp ) const [virtual]

Add all points referenced by the primitive to the given group. This defaults to iterating over the vertices and adding their referenced points.

Reimplemented in GEO_Hull, GEO_PrimParticle, GEO_PrimPasteDAG, GEO_PrimTriBezier, GEO_PrimVolume, GEO_Quadric, GEO_TriMesh, and GEO_VolumeElement.

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_Hull, GEO_PrimCircle, GEO_PrimParticle, GEO_PrimPasteDAG, GEO_PrimSphere, GEO_PrimTriBezier, GEO_PrimTube, GEO_PrimVolume, GEO_TriMesh, and GEO_VolumeElement.

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_Hull, GEO_PrimCircle, GEO_PrimParticle, GEO_PrimPasteDAG, GEO_PrimTriBezier, GEO_PrimVolume, GEO_Quadric, GEO_TriMesh, and GEO_VolumeElement.

virtual void GEO_Primitive::stashed	(	int	onoff,
		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 in GEO_Hull, GEO_PrimMetaBall, GEO_PrimMetaSQuad, GEO_PrimParticle, GEO_PrimPasteDAG, GEO_PrimTetrahedron, GEO_PrimTriBezier, GEO_PrimVolume, GEO_Quadric, and GEO_TriMesh.
