Shiva 3d scene scene

You need to create a scene in Shiva 3d in which at each launch a maze will be generated from heimobjects using this algorithm http://weblog.jamisbuck.org/2011/1/27/maze-generation-growing-tree-algorithm, the terrane is always the same and is not generated, only the maze is done.
Here are the objects https://r.mail.yandex.net/url/S3EI4k038WfRZDVFfgOYXg,1360530287/yadi.sk/d/1pyljuEh2WSJm
It is possible to build according to its own algorithm, if similar in complexity labyrinths are built.
