The proceural techniques presented in this technical breakdown use Pixar's custom mel procedures (part of RenderMan for Maya) to create secondary geometry at "render-time". The breakdown explains how a custom interface was added to Maya to enable the generation of the secondary geometry to be controlled in an artist-friendly way.

For this project, I basically used Professor Malcolm Kesson's scripts RiMel - rgbMeshArchives. However this script can only be used on a flat plane. I tried it on a cylinder and a sphere, it has some errors. So I made some change, so I can control Y-position also by reading the color. What's more, these scripts I created can also read several different Archives randomly.
when color on the map is red
when color on the map is green
when color on the map is blue
Adjust the height of the archives alone with the number of the grayscale from the ramp on the color map
if the number of Heights are 0, then the archives position on Y will not be controlled by color map. The result will be that all the archives stay in a horizontal plane.
if the number s of Heights are not 0, in this case the numbers are above 0. The archives position on Y will be placed like they are on a cylinder with this color map.
Thank You. :)
