texture mapping in python?

Hi there,

I'm trying to make sense of the TextureMapping and MappingTag objects in the Rhinocommon lib for python.. i spent quite some time but didn't find anything that brought me forward. It looks like it is possible to create planar/box/etc mappings, but i can't figure out how to set it up.
I saw 'thomas the tank engine's successful attempts in vb but it seems as if the classes and functions don't exist in the python lib..

Does someone have a snippet of code or can point to some information that gives a hint?

Thank you,

Lukas
