[Visualpython-users] vpython as a visualization window

[G. F. <grz...@gm...>]

Hi,


I'm writing an experimental brain atlasing tool and I'm looking for
visualization options. As I need to (or rather: want to) process my
geometry at a triangle level by hand, VTK seems to complicated.
I'm fairly proficient with opengl programming, so I feel comfortable
with pygtk / pygtkglext / and a custom widget handling simple mouse
interaction.
It's all pretty straight forward and seems the easiest way to
implement custom camera interactions or whatever fancy interface i can
imagine.

Of course using "raw" pyopengl has serious performance issues, and I
might be forced to code variable level of detail schemes for data
sizes I could otherwise throw at a c implementation without
hesitation.

So I'm basically looking at options to separate opengl drawing calls
and mouse interaction to a c implementation, while still being able to
modify my data from python, visual python looks really promising to
me, but I think I would only use the frame and faces primitives.
What I really need though is transparency options.

I know that the beta version doesn't support transparency for the faces shape.
I'm very curious what is the estimated time for this feature to
arrive? Are there any problems with adding transparency handling to
the faces renderer, compared with the other primitives?

I would also like to hear from anyone using visual python as a simple
polygon pusher / viewer. Maybe You can suggest something simpler?
