Hi there!

I am not new to 3d modelling/C programming.

But I am new to blender.

I am interested in the details how blender calculates the resulting mesh from an armature modifier, especially if only vertex groups, but no bone envelope influence is used.

Could someone please give some entry points, i. e. source file and line numbers?

I already browsed through the code, but is difficult to find if you don't have a clue about code structure and naming...

Thanks a lot!!!

hmm, this looks good:

source/blender/blenkernel/intern/armature.c, line 918
