void GEO_PrimTube::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.

void GEO_PrimTube::copyPrimitive ( const GEO_Primitive src)
overridevirtual

Implements GEO_Primitive.

void GEO_PrimTube::copySubclassData ( const GA_Primitive source)
overridevirtual

Copy all subclass data from source to this.

The vertex lists of source and this must already be equivalent in some manner, though possibly referring to different vertices.

If some subclass data is dependent on the vertex list contents, (such as GEO_PrimPolySoup::myPolygonVertexList), it should be mapped based on the correspondence between the two. GEO_PrimPolySoup is currently the only primitive type with this sort of dependence, so it's probably best not to add more.

NOTE: This must be safe to call on different primitives in parallel at the same time.

int GEO_PrimTube::evaluatePointV4 ( UT_Vector4 pos,

overrideprotectedvirtual

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.

int GEO_PrimTube::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.
