Class representing a planar [PrimitiveMesh]. Class representing a planar [PrimitiveMesh]. This flat mesh does not have a thickness. By default, this mesh is aligned on the X and Z axes; this default rotation isn't suited for use with billboarded materials. For billboarded materials, use [QuadMesh] instead. Size of the generated plane. Defaults to (2.0, 2.0). Number of subdivision along the Z axis. Defaults to 0. Number of subdivision along the X axis. Defaults to 0.
