Code outline bridging edge loops In the function that creates the new faces we have to perform the following steps: 1. Check that both edge loops are equally long and nonzero. 2. For every edge in loop 1: 1. Find the edge in loop 2 that is closest. 2. Create a face connecting these two edges. [ 42 ] Chapter 2 The function that implements this outline looks fairly complicated: def bridge_edgeloops(e1,e2,verts): e1 = e1[:] e2 = e2[:] faces= if len(e1) == len(e2) and len(e1) > 0 : The function takes two lists of edges as an argument and a list of vertices.

The first step involves creating body parts that are suitable for assembling together. This means we have to model these parts in Blender, defining suitable joints and marking those joints as vertex groups. Then we export these meshes as Python code by using a script that we encounter again in the next chapter as it deals with vertex groups. For now, we use this generated Python code simply as a module containing several lists of vertices defining each body part. blender\scripts\bpymodules would be a logical choice or alternatively the user scriptdir.
