here is some code I use for doing that. It could be written better, but I
was young. I needed the money. It has some code smell, but I dont' have
time to improve it.
import pymel.core as pmdef tfmAtCentroid(vertSel=None, tfmSel=None,
locator=True, name=None):
""" select verts and joints. snaps a joint to the centroid
position of selected verts. """
# SELECTED VERTS AND JOINTS
verts = vertSel or []
tfms = tfmSel or []
sel = pm.selected()
returnList=[]
# NOTHING PASSED IN OR SELECTED
if not vertSel and not tfmSel and not sel:
return
# IF NO ARGS PASSED IN GET SELECTED
if sel:
for item in sel:
# SORT THE SELECTION
if item.__class__.__name__ == "MeshVertex":
verts.append(item)
else:
tfms.append(item)
# JUST SELECTED WHOLE PIECE(s) OF GEOM
if tfms != [] and verts == []:
for tfm in tfms:
try:
pm.select("%s.vtx[:]"%tfm,r=True)
newTfm = tfmAtCentroid(locator=locator,name=name)[0]
returnList.append(newTfm)
except:
# NOT A MESH
if locator:
name = name or "%sNUL"%tfm
loc = pm.spaceLocator(n=name)
pm.delete(pm.pointConstraint(tfm,loc,mo=False))
returnList.append(loc)
else:
name = name or "%sJNT"%tfm
pm.select(d=True)
j = pm.joint(n=name)
pm.select(d=True)
pm.delete(pm.pointConstraint(tfm,j,mo=False))
returnList.append(j)
# HAVE TO RETURN HERE OR IT WILL CONTINUE ON AND MOVE YOUR TFM
TO THE ORIGIN
return returnList
# SELECTED SOME VERTS AND THATS IT
if tfms == [] and verts != []:
if locator:
name = name or "%sNUL"% verts[0].node()
loc = pm.spaceLocator(n=name)
tfms.append(loc)
returnList.append(loc)
else:
name = name or "%sJNT"% verts[0].node()
j = pm.joint(n=name)
pm.select(d=True)
tfms.append(j)
returnList.append(j)
pm.select(verts,r=True)
# CREATE A CLUSTER TEMPORARILY
clsNode, clsHandle = pm.cluster()
for tfm in tfms:
# SNAP JOINTS TO THE CLUSTER HANDLE
pm.select(d=True)
pm.delete(pm.pointConstraint(clsHandle,tfm,mo=False))
#DELETE THE CLUSTER HANDLE
pm.select(d=True)
try:
pm.delete(clsNode,clsHandle)
except: pass
return returnList
