Re: [Visualpython-users] basic questions

[Bruce S. <Bru...@nc...>]

VPython implements a second "rendering" thread which about 25 times per second 
interrupts your computations to create a 3D image (using OpenGL) from the 
current attributes of the objects, and the current (mouse-determined) "camera" 
viewing angle. A complete rendering is done each time (25 per second) even if no 
object has changed nor the camera has moved. For this reason performance with 
very large numbers of objects is likely to be poor, but it's easy enough to test 
simply by creating a very large number of objects. You could make the window 
invisible while computing, so as not to be interrupted by rendering, but once 
you make the window visible you may see poor performance for zooming and rotating.

The cheapest object to render is "points" which makes 2D disks or squares 
positioned at 3D locations. It is moreover an array object, with a list for the 
positions of the points.

Please say more about your question regarding zoom and rotate. What is "wild" 
about using the mouse to rotate or zoom the camera for looking at the scene?

There is documentation on mouse manipulations in the Visual help available on 
the Help menu in IDLE. Under Windows, Events, & Files see Mouse Events. Also, in 
the contributed section of vpython.org are some example programs that do fancy 
things with the mouse. And see the Tutorial on the first page of the help for 
the basics on using the mouse to zoom and rotate.

[Visualpython-users] basic questions

[Tim S. (25121) <tk...@mi...>]

1.	Can vpython handle large datasets? I'm considering using it for
a project modelling a large geographical body, I might need to plot
1,000,000 points or more.
2.	What would be the best object to use ?
3.	Is there a tutorial on mouse manipulation so I can zoom in and
out and rotate my object? The default behaviour seems a bit wild

Dear Guy,

I have try those steps you mentioned but I still can get my VPython working.
After I run my Python script in idle, it just show a RESTART line and did
nothing. Am I missing something? I install VPython using the repository, not
compiling the source.

[Visualpython-users] Python(xy)

[Bruce S. <Bru...@nc...>]

I have a vague recollection of some problem being reported with using 
VPython in the Python(xy) distribution (www.pythonxy.com). I couldn't 
find anything in the VPython mailing list archives, but doing a search 
for "Python(xy)" just gave results for Python, which wasn't helpful.

Can anyone enlighten me on this? I just did the experiment of installing 
Python(xy) on Windows, and it comes with a working version of Visual 
5.13 and even has VIDLE, though it is defective in missing the crucial 
startup file idle.pyw.

[Visualpython-users] a fix for Ubuntu Karmic is available

[Guy K. K. <g....@ma...>]

Hello all,

good news! Andrew has tracked down a fix by backporting a patch from 
Boost.Python's Py3k development to the current Boost 1.38 libraries as they're 
present in the current Ubuntu release (Karmic, 9.10).

Notes can be found here:

https://bugs.launchpad.net/ubuntu/+source/boost1.38/+bug/457688

So for now the fix is as easy as adding the PPA to your system and doing an 
upgrade:

$ sudo add-apt-repository ppa:ajmitch
$ sudo aptitude update
$ sudo aptitude full-upgrade

As far as I got it, this patched version is also supposed to make it into the 
bug fixes for the running Ubuntu release, so that it should be usable by some 
point of time from the normal repositories.

Let me know if you should still encounter somewhere any other misalignments 
with the python-visual or Boost packages regarding this issue. Or even better, 
add a comment to the bug under the URL above.

Guy

No, not really, but ...

I've attended Kiwi PyCon [1] this weekend, and met quite a few 
Launchpad/Ubuntu developers there. The bug responsible for the mis-behaviour 
[2] has just been promoted to importance level "high", so it is likely to be 
fixed during the life time of Karmic, rather than waiting for 10.04. Having 
said that, they're trying to dig through the current Boost.Python SVN working 
branch to pick out the change that made Boost work again, and backport a patch 
to the current deployed stable version 1.38.

So, let's keep our fingers crossed so that things will start working again 
soon.

Guy

PS: BTW, side note from the Canonical developers @ Kiwi PyCon: If something's 
not up to your needs, and you want to get attention from the Ubuntu teams, 
file a bug report on Launchpad. They *do not* listen in on rants on the Ubuntu 
forums, as they're swamped with bug and enhancement requests already, and the 
bug tracker is the only thing they can possibly manage without losing their 
sanity.

[Visualpython-users] How can I export an image file in Vpython programmatically

[xingran x. <xxi...@gm...>]

Hi, all

My application is to visualize some user-input data. Users upload data
files through the web interface, I need to visualize the data and
render it in a Web page, I do not need the interaction ability of
vpython(like drag, zoom...etc), a basic visualization is enough,
sort-of like a screenshot of the initial view of Vpython
visualization...but since it is a Web application, I need to do it
programatically.

Any input will be greatly appreciated, thanks!

Re: [Visualpython-users] VPython in Karmic using Python 2.5

I'm not absolutely certain of this, but I think this comes from using

Hi all,

I have been following the efforts of trying to get VPython run in Karmic
using the default Python and Boost libraries. I am trying to get it working
too but failed. Anyway, I try to use Python 2.5 to compile the source as I
was able to do that in Jaunty. However, the make process failed. The last 2
lines of build.log are:

/usr/bin/ld: cannot find -lboost_python

I tried compiling version 5.13 and 5.11. The results are the same. Thanks in

According to
     http://mail.python.org/pipermail/python-dev/2009-October/093188.html
the problem may be fixed by moving to the very most recent Boost (the

There is nothing built-in. On most platforms there is a way to capture a bitmap

Alt-Print Screen, then paste into some application such as Word.

For high-resolution images, see the discussion about povexport in the FAQ

Re: [Visualpython-users] The cvisual attributeError

Because Visual at present cannot work with Python 2.6.3 (due to changes in 
Python in going from 2.6.2 to 2.6.2) I've placed on the download pages at 
vpython.org the advice to use 2.6.2. I'm guessing that there's a typo in the

Re: [Visualpython-users] The cvisual attributeError

[Tony R. <To...@br...>]

What is known so far is in this bug report and all the links therein:

https://bugs.launchpad.net/ubuntu/+source/boost1.38/+bug/457688

There seems to be some incompatibility with python 2.6.3 and boost
python 1.38-1.40; many projects utilizing python boost seem to be
experiencing this.

You may have had an older version of boost that later got updated.  I
have confirmed that using the trunk version of boost fixes this,
although in windows you may need to downgrade boost to pre 1.38 (I
believe this is where the regression occured but it may have been 1.39)

[Visualpython-users] The cvisual attributeError

[Bryant M. <bm...@ya...>]

Greetings:
I am just getting started in Python and consiquently have many modules etc installed, not knowing what I really need. I had just discovered how to get eric4 and Vpython 5.13 installed using Python 2.6.3. On the 20th I was able to run the begining tutorials which included the import visual line with no problems. Last night I ended up with the object attribute error. 

Traceback (most recent call last):
  File "<pyshell#0>", line 1
    from visual import *
  File "C:\Python26\lib\site-packages\visual\__init__.py", line 59
    import cvisual
AttributeError: 'Boost.Python.StaticProperty' object attribute '__doc__' 
is read-only

What had occured between was the installation/uninstall of an ACAD2010 trial package that included the C++ 2008 redidstribution package and updates. I already have Vstudio 2005. Also cmake 2.6 was installed. I have removed the C++ redistribution packages and the ACAD program and reinstalled all my python packages but am still unable to import visual. I dont know if any of this provides clues but I was able to import visual in 2.6.3 with no errors.

Re: [Visualpython-users] Wireframe Mode

[Tony R. <To...@br...>]

Actually now that I think about it, frames with the ability to locally
scale their axes might be pretty cool and useful...

Re: [Visualpython-users] Wireframe Mode

[Tony R. <To...@br...>]

Well I know we can't smash the two togeter as is, but maybe accounting
for the scale so they can coexist on the same display, or putting 2D
nonrotational stuff in an "overlay" that is glued to the viewport,
with points translatable to their respective axes in the 3D part.

I'm not sure I said it very elegantly, but this is somewhat how I'm
implementing a HUD in my own log visualizer app; I have a dedicated
"viewport" frame that gets moved and objects scaled as the camera
moves so they always appear stationary, or I put everything into
frames and the global frame becomes the overlay.

I posted awhile back about an arbitrary frame transformation routine
and this is how I'm using it.  Seems like 2D stuff could be added like
this, but would additionally need to remember any scale factors
between an object and the global frame so the points could be
translated.
