PlaneSurface Methods

Computes the curvature at the given UV coordinate.

Returns a CRC calculated from the information that defines the object. This CRC can be used as a quick way to see if two objects are not identical.

Actively reclaims unmanaged resources that this instance uses.

Overridden in order to destroy local display cache information

Gets the domain in a direction.

Constructs a deep (full) copy of this object.

Constructs a light copy of this object. By "light", it is meant that the same underlying data is used until something is done to attempt to change it. For example, you could have a shallow copy of a very heavy mesh object and the same underlying data will be used when doing things like inspecting the number of faces on the mesh. If you modify the location of one of the mesh vertices, the shallow copy will create a full duplicate of the underlying mesh data and the shallow copy will become a deep copy.

If you want to keep a copy of this class around by holding onto it in a variable after a command completes, call EnsurePrivateCopy to make sure that this class is not tied to the document. You can call this function as many times as you want.

This routine accepts a 3-d trim curve (trimCrv3d). The trim curve is assumed to run from one surface edge to the opposite edge; this is referred to as a "simple" trim curve, roughly parallel to one of the srf directions (either u or v). We refer to that parameter as the "trim parameter". The routine splits the surface via the trim curve, and then refits either side ("upper" = "above the trim", and "lower" = "below the trim") as a set of untrimmed Nurbs surfaces. The idea is to retain, as much as possible, the Nurbs structure of srf, especially in the trim parameter.

Splits the surface into two and refits the split edge

Reverses parameterization Domain changes from [a,b] to [-b,-a]

Same as Reverse, but if inPlace is set to true this Surface is modified instead of a new copy being created.
