[Visualpython-users] Export geometry to obj, fbx or a common geometric 3D format OR access the data of the geometric models so that I can store it to file.

[Magnus E. <Mag...@ho...>]

Hi,

I have spawned a bunch of spheres and other shapes to represent a dataset. Now I need to store all these primitives as a single object in a format that is useful.

For example, I have one part that consists of 654 spheres which I want to store to disc as a single obj model or as any similar file.

There seems to be no OBJ exporter or 3DS exporter or FBX exporter or STL exporter. This I find to be very strange as it is a glaring missing piece. There are no method to store the geometry that you create? I must be mistaken so I am asking here because my google-fu is not good enough it seems.

I am looking forward to your reply. Thank you for your help.

Yours,
Magnus Elden

heh, I generate OBJ and POV files in parallel with my VP model.

I've heard that Ruth Chabay made a POV exporter; perhaps you could adapt 
that.

(what's POV, you ask? see povray.org)

What's all this? I thought visualpython was dead, this group only 
available via google news, gmane in a long term restructuring. I was 
planning to go deep down into the lower layers of opengl and port my 
work to pi3d.

And now there's life?

This email list is indeed dead, but Magnus Elden found it using Google,
alas. It has long been superceded by the VPython forum at

https://groups.google.com/forum/?fromgroups&hl=en#!forum/vpython-users

VPython itself is very much alive. See vpython.org.

Thanks for replying, and sorry for hijacking the thread, and for 
performing necromancy on a dead email list.

 From over here things seem a bit different.

What I came to know and love as vpython had been rebranded "classical 
vpython" and is no longer maintained.

I want a vpython free of all kinds of encumbrances and dependencies on 
corporations, webbrowsers and integrated development environments. In 
fact I want it to be as lean and mean a layer over opengl as humanly 
possible to program, while still retaining all the nice abstractions.

I believe that it was long overdue for vpython to switch away from using 
compiled C code, specifically boost, and instead to start to use ctypes 
or cffi. That would mean one could much easier maintain and develop it, 
because there would be no code compile run loop and instead one would be 
accessing already compiled functions that exist in some system library.

Pi3d is an example of the kind of this thing I'd want, except of course 
vpython (the classical vpython) has a much larger mindshare and cultural 
background, based on a long history of use.

I suspect that maybe some of these considerations have been at the basis 
of your decisions, unfortunately resulting in a direction that doesn't 
please me too much :( but that I think I can understand.

Have a look at http://vispy.org/ as well.

It seems vpython-users doesn't allow mailing list-type subscriptions, 
which seems a bit odd as I thought Google Groups allowed that. Maybe 
that's only for gmail.

These vispy people seem to be on a whole new level of ignorance about 
privacy and user safety, beyond for example vpython using a google forum 
that mandatorily requires one to run javascript in the browser, opening 
one up to those scripts calling other scripts etc., no, these people 
never even learned to feel ashamed if some *python* script "needs to 
load a few files from the Internet" in the background. It's probably 
useless to call them out on it because they would start calling one a 
paranoid or something like that.
