[Visualpython-users] Mesh questions

[Ryan H. <rf...@ma...>]

I have 2 questions regarding the use of the Mesh Class provided with the =
examples.  These are perhaps trivial but I can't seem to figure them =
out:

1) Once I've created a Mesh Object, is there a way to turn it on and =
off?  With most other visual objects there is an attribute "visible" =
which I can just set to 0 to turn the object off.

2) Is there a way to crop a mesh object to display only parts of it =
inside some specific domain?  For example, the surface I'm working with =
looks awkward when viewed inside a box and I'd like to take this surface =
and just see those parts of it that lie within a sphere of some radius.  =
This would be easy to do if I had some nice parameterization of the =
surface in spherical coordinates, but best I can tell there's no simple =
parameterization of this surface.

Thanks for any help you can offer,

I guess you're referring to a routine in the example program 
faces_heightfield.py. That's not a class that's part of Visual, it's 
just something that the author of that program (David Scherer) wrote for 
the particular purposes of that example. It doesn't do any of the things 
expected of Visual objects, nor is there any documentation of it. Feel 
free to take it and do whatever you want with it.
