Find 3D Lighting: get3_light

Calling Sequence

...

  
get3_light(xyz [, nxyz])

Description

Return 3D lighting for polygons with vertices XYZ. If NXYZ is specified, XYZ should be sum(nxyz)-by-3, with NXYZ being the list of numbers of vertices for each polygon (as for the plfp function; see page ). If NXYZ is not specified, XYZ should be a quadrilateral mesh, ni-by-nj-by-3 (as for the plf function; see page ). In the first case, the return value is len (NXYZ) long; in the second case, the return value is (ni-1)-by-(nj-1).

The parameters of the lighting calculation are set by the light3 function (see ``Lighting Parameters'' on page ).
