[Bf-python] Project suggestions (thinmesh maybe?)

[Willian Padovani Germano]

Hi Ken,

You've been playing major role for the next bpython release, thanks a 
lot for that.

About a new mesh module, I've been thinking frequently about it these 
days, because of the recent trouble with nmesh.update(). Writing the new 
module to the point of having something fast and useful for many 
applications should not take that long.

If you want to tackle this I can help with any troubles.

Basic idea is to have it as a thin wrapper (like Camera, Lamp, etc. etc. 
modules) over mesh data (mesh, verts, faces, edges). The name could be 
Blender.Mesh, simply. Verts, edges and faces (let's call them elements 
here) would be subtypes, mesh.verts would be a list with proper methods 
(assignment, slice, etc.) to keep memory usage as small as possible, 
equiv. for mesh.edges and mesh.faces.

As a first milestone while developing, a first version of the module 
doesn't need to deal with creation / deletion of elements. Being able to 
move verts around is already a useful feature for many scripts. To deal 
with deletion / addition, we should take a good look at how Blender 
itself is doing things and if possible try to use that.

One issue is deformed data. In NMesh there's a function to get deformed 
verts, you know. Something equiv. should be available in the new module.

Anyway, discussing Mesh before writing it is not a bad idea and this is 
a good time for it, so you all are more than invited to give 
suggestions, of course.

BTW, Martin (theeth) also was interested in a new mesh module and he 
wrote gmesh, so he probably has ideas to share.
