Is there a way to list volumes in a menu parameter?

[magneto]

Hi,

 

I have a menu parameter and I am trying to list the volumes in the input geometry. I know how to list attributes but for volumes, do I have to iterate though all prims and see if they are volume? Because if I have millions of polygons and 2 points, it seems wasteful.

 

Maybe there is a faster way?

 

 

Thanks

Use hou.Geometry.globPrims(pattern) method with an ad-hoc group expression @intrinsic:typename==VDB,Volume.

import itertools

pattern = '@intrinsic:typename==VDB,Volume'
volumes = hou.pwd().geometry().globPrims(pattern)
tokens = [v.number() for v in volumes]
labels = ['Volume #%i'%n for n in tokens]

return list(itertools.chain(*zip(tokens, labels)))
