The world space position of the vertex is determined using the

p0i ntP0si t i

on com-

mand with the -w flag. If the object space position of the vertex is needed, simply use

$pos = "getAttr $verts[$v]';.

$pos = "pointPosition -w $verts[$v]'.

The uv coordinate is retrieved by using the getAttr command. It returns an array of

two floats.

$uv = "getAttr $uvs[$v]'-

There is no standard MEL command to give the valency of a vertex. It can be calcu-

lated, however, by counting the number of edges sharing the vertex. The
