I have a grid.I want to find the number of polygons points and prims in the grid.could anyone share a code snippet.thnks

geo = hou.node().geometry()

npts = len(geo.points())

npr = len(geo.prims())

print npts

print npr

not sure what you mean by polys as a poly is a prim, unles its a mesh.

coool

can we also find uv cordinates and the number of vertices

Yes!

test =0
for x in geo.prims():
     test = test+x.numVerticies()

print test

also this brought up the realisation that prims is a rather generic term. Perhaps you were referring to faces earlier?

Prim Type

I found this one interesting

hou.primType.Mataball (sp?)

as for uv's i think this is what you're after, but hmmmm

sorted.... wow the more i use python the more amazing it gets.. the level of control is unprecedented!!!

attr = geo.findVertexAttrib('uv')
for x in geo.prims():
     for y in x.verticies()
          print y.attribValue(attr)
