coloring a plane dinamically - Macromedia Director 3D

[cobian webforumsuser@macromedia.com]

Hi, I have developed a script that creates a 3D chart from an array of two dimentions. This array describes the depth of the vertex of the chart, which is generated from a plane, and moving the vertex with the meshDeform modifier.
My question is:
I want to colorate this plane: the lower zones in blue, the higher in red, with all the intermediate colors. How can I create a shader to do this?
Can anybody give me a hint?
Thanks

I think the easiest way would be to apply a simple color fade texture to the edge of the object. This would automatically color the object smoothly like a contour map without worrying about having to build your own mesh and code the colorList for each vertex.

Also from what I've found, the colorList method for creating meshes from scratch does not render consistently across all 3D cards and bit depths, so stick to the texture method to avoid headaches.
