I am trying to 'extract and convert' all the edges of the polygon (based on
selection) into curves, then parent the curves as one. This is like a
curve-based wireframe model.
While Maya has a functionality that allows all edges to be converted into
curves, but the functionality - "Polygon Edges to Curves", it works but not
very ideal in my case as I would want all the created curves to be combined
into one.
import maya.cmds as cmds
import pymel.core as pm
edges = cmds.filterExpand(cmds.polyListComponentConversion(te=1),sm=32,ex=1)
cur_list = []
for edge in edges:
vtx = cmds.ls(cmds.polyListComponentConversion(edge,fe=1,tv=1),fl=1)
p1 = cmds.pointPosition(vtx[0])
p2 = cmds.pointPosition(vtx[1])
created_curve = cmds.curve(d=1,p=(p1,p2))
cur_list.append(created_curve)
# Select all the newly created curves
for cur in cur_list:
cmds.select(cur, add=True)
# Get list of objects
shape_list = pm.ls(pm.listRelatives(c=True))
grp_list = pm.ls(pm.group(em=True, n='curve#'))
list_all = []
for obj in grp_list:
list_all.extend(shape_list)
list_all.extend(grp_list)
# Parent (shape) objects to one Curve
pm.select(list_all)
pm.parent(r=True, s=True)
While this code of mine does work, but if I tried to use it on a higher
subdivision polygon, for example, create a normal pSphere and sets both its
"Subdivisions Axis" and "Subdivisions Height" to 100, and execute the code
I wrote.
What happens here is that:
- Maya seems to be hanging
- Took a very long while to be process (seems to be more than 1 hour
plus before that current maya session of mine crashes.)
What can be done to minimize this long processing time? I am assuming that
part of this 'long' time is due to the commands that I am using it to
derive the vertex and creating them?
