DESCRIPTION

splf draws Gouraud-shaded polygons using the current pattern and writemask. It takes three arguments: parray, an array of points; array, an array of the intensities at these points; n, the number of points in each array. Polygons are represented as arrays of points. The first and last points automatically connect to close a polygon. The points can be expressed as integers, shorts, or real numbers, in 2-D or 3-D space. 2-D polygons are drawn with z = 0. After the polygon is drawn, the current graphics position is set to the first point in the array.

All polygons must be convex.
