Method for helping curve fitting on a set of data points. Given a set of data points dataPts[0..n][0..2]. Compute the unit tangent vectors for local interpolation methods, and indicate possible corner points if needed. To specify that you want to detect corners, set the column dimensions of tangents to 0..5 per point) else set tangents[0..n][0..2]. Output: tangents[0..n][0..2||5].

	)		const

overridevirtual

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.

Implements GEO_Primitive.

void GEO_Curve::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.
