How Function Based Shading is working ??

[sasikumars93559897]

The Function Based Shading is the Shading Type 1.Can anybody give the example of Function Based Shading....

Here's an example taken from my Advanced PostScript course. It creates a shaded region by interpolating

among two rows of six samples.

Hope this is useful.
