public class RectangleMesh extends com.jme3.scene.Mesh
A 2-D, static, TriangleFan-mode mesh that renders an axis-aligned rectangle in the X-Y plane.

In local space, the rectangle extends from (x1,y1,0) to (x2,y2,0) with normals set to (0,0,zNorm). In texture space, it extends from (s1,t1) to (s2,t2).

The key differences between this class and com.jme3.scene.shape.Quad are:

  1. the center and extent can be configured independently,
  2. TriangleFan mode is used to reduce the number of indices from 6 to 4,
  3. the normal direction is configurable, and
  4. the texture coordinates can be configured in greater detail.
