PLUGIN REQUEST: material by slope

[icepam]

Hi everyone, i've looked everywhere but can't find a plugin that would assign materials/color a terrain or set of faces based on the slope of each.

It shouldn't be too hard to put together using TIG's routines to measure slope of roof in his roof plugin, and something similar to Chris Fullmer's COLOR BY Z. {basically it's COLOR BY NORMAL ANGLE}. unfortunately i don't know ruby.

Any tips?

PS here's some examples of a slope analysis (some would call it gradient analysis): http://www.seismicactivity.de/Software/fracland/cm1.jpg

"color by normal angle".....I had not ever thought of it like that. This is a plugin I've wanted to forever (and color by z was sort of the closest I could come.

Perhaps color by normal angle sheds some light on this topic that might make it possible. I'll give it a go if no one else does.
