Methods

Method	Description

ToString	Obtains a string representation of the current instance.

Properties

Property	Description
BasisType	Retrieves or sets the type of curve used to construct the patch.
Degree	Retrieves or sets the degree of the curves used to construct the patch.

Remarks

A mesh is a set of faces, each of which is described by a simple polygon. Objects can be created by connecting several meshes together. A patch mesh is made up of patches, which are four-sided pieces of geometry that are constructed from curves. The type of curve used and the curve's order can be varied so that the patch surface fits almost any surface shape.

The following types of patch combinations are supported.

Patch Type	Basis	Degree
Rectangle	Bezier	2,3,5
Rectangle	B-spline	2,3,5
Rectangle	Catmull-Rom	3
Triangle	Bezier	2,3,5
N-patch	N/A	3
