So this is almost working. Although I'm not really getting the orientation I'd
like for verts on non-flat meshes. In some areas, it works great, in others -
I'm not sure how to get the proper orientation. Any ideas on how to make this
better? if you run it with a really lowpoly sphere selected you can see what I
mean towards the poles.
#=======================
import pymel.core as pm
def getVtxTfm(vtx):
pos = vtx.getPosition(space='world')
xVec = vtx.getNormal()
connectedVertNames = [ vert.name() for vert in vtx.connectedVertices() ]
nextVertName = "{0}.vtx[{1}]".format( vtx.node().name(), ( vtx.index() + 1)
)
nextVert = pm.PyNode( nextVertName )
prevVertName = "{0}.vtx[{1}]".format( vtx.node().name(), ( vtx.index() - 1)
)
prevVert = pm.PyNode( prevVertName )
if nextVertName in connectedVertNames:
yVec = ( nextVert.getPosition() - pos ).normal()
else:
yVec = -( prevVert.getPosition() - pos ).normal()
zVec = xVec.cross(yVec).normal()
yVec = zVec.cross(xVec)
mat = pm.datatypes.Matrix()
mat.a00 = xVec[0]
mat.a01 = xVec[1]
mat.a02 = xVec[2]
mat.a10 = yVec[0]
mat.a11 = yVec[1]
mat.a12 = yVec[2]
mat.a20 = zVec[0]
mat.a21 = zVec[1]
mat.a22 = zVec[2]
mat.a30 = pos[0]
mat.a31 = pos[1]
mat.a32 = pos[2]
tfm = pm.datatypes.TransformationMatrix( mat )
null = pm.spaceLocator()
null.setTransformation( tfm )
sel = pm.selected()
nodeName = sel[0].name()
for vtxID in sel[0].getVertices()[1]:
vertex = "{0}.vtx[{1}]".format( nodeName, vtxID )
vert = pm.PyNode(vertex)
getVtxTfm(vert)

Thanks!
