I’m planning to write a subdivision surface modeller just for fun :-), but there are some things I just can’t make sense of (in terms of subdivision surfaces)…
Maya provides hierarchical subdivision surface modelling while XSI does not. But as far as I understand both of them are true subdivision surfaces because they both use the Catmull-Clark subdivision scheme or another one like Doo-Sabin.
Now I’m wondering if the whole hierarchy thing is actually an improvement or enhancement by Alias or if it is just not yet implemented in XSI? Is it part of a subdiv “specification” (if such a thing exists)?
Honestly I can’t see a major advantage of Maya’s hierarchical modelling over XSI’s subdivisions because you can subdivide the polygon base mesh and so you’re able to get local detail without a hierarchy. Or do I miss something here?
