<DIV><FONT face=Arial size=2>Hello!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Are there any plans to add a "face.index" attribute
to python? </FONT><FONT face=Arial size=2>If not - take this as a proposal
;-)</FONT></DIV>
<DIV><FONT face=Arial size=2>My question is because i've come across this
problem when writing some functions for computational geometry (like
computing convex hulls and voronoi diagrams):</FONT></DIV>
<DIV><FONT face=Arial size=2>For these algorithms you have
to maintain lots of information for vertices and/or faces - like
adjacent faces, common edges, common vertices, ...</FONT></DIV>
<DIV><FONT face=Arial size=2>Usually i store information like this in lists
or dictionaries.</FONT></DIV>
<DIV><FONT face=Arial size=2>- Storing a vertex in a list or as key inside a
dict is easy - simply take the vertex.index as key and store any information you
need as values. </FONT></DIV>
<DIV><FONT face=Arial size=2> Then you can do any processing on
the lists/dictionaries and when you're done you can access the
'real' vertex of the mesh again - it's mesh.verts[index].</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>- Unfortunately there's no such thing for faces.
Sure you can use a tuple of the vertex indices that make up the face
as key. This works fine. But if you want to access the 'real' face again
you've got a problem...</FONT></DIV>
<DIV><FONT face=Arial size=2> Wouldn't it be nice if we could have a
face.index attribute as well? This could be used as key in dictionaries and you
could later access the face again with mesh.faces[index].</FONT></DIV>
<DIV><FONT face=Arial size=2> </FONT></DIV>
<DIV><FONT face=Arial size=2>This would also make processing information for
faces and vertices more consistent.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any thoughts or comments on this?</FONT></DIV>
