Hi, thanks for all the infos. I've briefly looked, and my first conclusion is... I need to read it again, but not at the end of a work day :) All that is completely new for me (mesh, tessellate, quads...), and I fear it will be too difficult... but let's try !
btw, can you point me to the page where there is the code on Paul Bourke website ? (I think I've found the theory page, but if there is some code...)
