Retrieve visible vertices

[vladsterz]

Not really an issue, more of a question. Is there a way to retrieve the visible from a given viewpoint vertices?

Solution?

Hey. If I remember correctly I was only to find visible faces.

late to the party, but here's how to get visible vertex indices from an opendr renderer
(any of the derived renderer classes should work for this):

def visible_vidxs(rn):
    """given renderer rn, return a list of visible vertex indices"""
    visible_fidxs = np.unique(rn.visibility_image[rn.visibility_image != 4294967295])
    visible_vidxs = np.unique(rn.f[visible_fidxs].ravel())
    return visible_vidxs
