[Visualpython-users] rotating frames

[Lenore H. <lh...@si...>]

I thought I could grab VPython output frames and rotate to different  
viewpoints with the mouse by default.  Was that just wishful thinking  
or is something not working for me that I can't do that?

Thanks,
Lenore

Ah! Sharp eyes!

Not only is the folder name possibly problematic, at least in the past 
one was strongly urged NOT to install Python into Program Files but 
allow the Python installer to install into C:\PythonXY.

This first problem might go away if visual is installed on a path
that does not contain any non-ascii characters.
It looks like your ó is not being handled well.

Sorry, I don't have any good ideas. I think the research group somewhat 
accidentally stumbled on the answer to their question. I guess a 
possible area of concern is anything having to do with the graphics 
driver, or OpenGL.

It's probably diagnostic of something that you have these problems with 
both Python 2.5 and 2.6, since one would expect differences.

Re: [Visualpython-users] Weird error importing visual

[Davidmh <dav...@gm...>]

First: I have had the same problem with the new version. Plus, I need
some libraries that are only available to 2.5.

Respect to the installing, no, I haven't installed anything in both
computers recently. But, rethinking in it, it may be caused by an
update of any program. Do you have any ideas of how could I trace it?
Do you know how they knew what was the problem?

This is not familiar. The only prior case I know of that seems a bit 
similar is that a group using VPython for research visualization had 
strange failures until they discovered that the problems were somehow 
caused by their having installed a particular video program, completely 
unrelated to Python. Do you recall recently installing a new program on

Although I know of no reason why it should matter, you might upgrade to

[Visualpython-users] Weird error importing visual

[Davidmh <dav...@gm...>]

Hello.

Recently, when I tried to execute a working program depending on
VPython, it raised an error importing the library. That was not fixed
reinstalling the whole Python interpreter and libraries.

It happened suddenly in my fixed computer, I cannot relate it to any
change in it, but in my laptop was still operative. Some weeks later,
I run a trivial program (just creating the scene and plotting an
sphere) in my laptop, worked; I ran it again just before and there was
the error I could not get rid of.


I use Python 2.5.4 and VPython 5.11 over WXP, Professional (fixed) and
Home (laptop),  both with antivirus NOD32 4.0, and the error are:

The first time I run the program in the Python IDLE:

>>> import visual
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import visual
  File "F:\Archivos de
programa\Clasificados\Programación\Python\2.5\lib\site-packages\visual\__init__.py",
line 83, in <module>
    cvisual._set_dataroot( _os_path.split( __file__ )[0] + _os_path.sep)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xf3 in position
47: ordinal not in range(128)


And if I try it again, I get:

>>> import visual
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import visual
  File "F:\Archivos de
programa\Clasificados\Programación\Python\2.5\lib\site-packages\visual\__init__.py",
line 70, in <module>
    del ui, crayola, primitives
NameError: name 'ui' is not defined


Any ideas of what is happening and how to solve it? Thank you very much.

Regards.

David Menéndez.

[Visualpython-users] VPython 5.31

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

VPython 5.31 released for all platforms. Kadir Haldenbilen made further 
corrections to the ttfquery and FontTools modules, which fixed a variety 
of errors in rendering 3D text. I fixed an error in updating various 
positions such as text.lower_right when you changed text.height.

If a relatively ordinary font gives an error in a text object, please 
report it. Thanks.

Re: [Visualpython-users] Two different displays showind the very same objects ?

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

No, there isn't a way to do that. However, in the documentation under 
"Work with 3D objects" choose "Additional options" to read about copying 
objects from one display to another. After copying you would need to 
update both sets of objects yourself.

I would like to have two or more different synced views of the same

[Visualpython-users] Path to success with {K}Ubuntu Lucid?

[Luke <haz...@gm...>]

Has anybody successfully installed Visual Python on the new Ubuntu 10.04 LTS
beta1?  If so, it would be great to hear about what the steps were; from my
understanding, the default packages in the repositories don't work out of
the box.

I'm looking at upgrading in the coming weeks and it would be great if Visual
Python would just work, like it used to.  What needs to happen in order for
the neccessary fixes / patches to make it into 10.04?

[Visualpython-users] VPython 5.3

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

VPython 5.3 is now available for all platforms. It offers the following 
enhancements.

*New 3D text object*

Thanks to great work by Kadir Haldenbilen, there is a new "text" object 
that from any True Type (.ttf) font produces extruded 3D text. This 
supercedes the very limited old visual.text machinery (which however is 
being left in place for upward compatibility). Kadir had to identify and 
exploit various font-related modules to find a font, identify its 
contours, and split the solid portions of characters into triangles to 
be used in a faces object. These additional font-related modules are 
bundled into the Windows and Mac versions. As usual, until and unless 
someone makes a distribution package, Linux users will have to install 
them manually: they are FontTools, ttfquery, and Polygon.

See the detailed documentation on the new text object in the help that 
is installed with VPython.

You may find some minor glitches. For example, the "&" is filled in on 
the sans-serif font Verdana, other fonts show o's and other such letters 
filled in, and some fonts give execution errors due to being ill-formed. 
You are invited to report problems with fonts or specific characters of 
fonts.

Polygon is being distributed in the Windows and Mac installers subject 
to the following conditions: "This distribution contains code from the 
GPC Library, and/or code resulting from the use of the GPC Library. This 
usage has been authorized by The University of Manchester, on the 
understanding that the GPC-related features are used only in the context 
of this distribution. It is not permitted to extract the GPC code from 
the distribution as the basis for commercial exploitation, unless a GPC 
Commercial Use Licence is obtained from The University of Manchester, 
contact: http://www.cs.man.ac.uk/~toby/gpc/".

*Enhancements to faces object*

You can now create a faces object f, specifying only the positions of 
the vertices, then use f.make_normals() to create normals that are 
perpendicular to all the faces. You can also use f.make_twosided() to 
convert a one-sided faces object into a two-sided one. You can now say 
f.append(pos=(x,y,z)), whereas formerly you also had to give a normal 
when appending a vertex.

You can use the previously announced f.smooth() to average similar 
normals in adjacent triangles to make the object look smoother, and with 
VPython 5.3 you can specify the smoothing criterion: f.smooth(0.7) means 
that normals whose directions differ by an angle whose cosine is greater 
than 0.7 (about 45 degrees) will be averaged. The simple form f.smooth() 
corresponds to f.smooth(0.95), in which case normals within 18 degrees 
of each other will be averaged.

*Highlighting a curve when making a graph*

When using gcurve to graph a function, there is a problem that you may 
not notice any plotting if the function repeats back on itself. You can 
now highlight the current plotting position in the gcurve by specifying 
a "dot" option: gcurve(dot=True). By default the dot has the same color 
as the gcurve, is round, and has a width of 8 pixels. You can change 
these defaults: gcurve(dot=True, dot_color=color.blue, shape='square', 
size=15).

*Minor bug fixes*

Some bugs were fixed. The helix object didn't have a "visible" 
attribute. If you had more than one points object, some with round 
points and some with square points, you saw only round points. Some 
technical bugs in the faces object were corrected.

[Visualpython-users] Mac problem resolved

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

I feel halfway between being betrayed and being an idiot.

In all my previous uses of PackageMaker to build installers for the Mac, 
the entities placed into site-packages were all folders, for which one 
must give the folder name in the destination as well as in the source, 
so for the visual folder I had to specify "Move stage/visual to 
site-packages/visual".

This time however it was necessary to place a file FontTools.pth into 
site-packages, and I assumed that I had to specify "Move 
stage/FontTools.pth to site-packages/FontTools.pth". Wrong! For a file, 
as opposed to a folder, you have to say "Move stage/FontTools.pth to 
site-packages/". For folders, if you don't repeat the folder name in the 
destination, no folder is created, and all the files in the source 
folder are spilled into site-packages.

I suppose there's some way to view this behavior as "normal", though to 
this bemused person it looks inconsistent.

I expect to be able to post VPython 5.3 today for all platforms.

Re: [Visualpython-users] Mac help?

[Steve S. <st...@sp...>]

Hi Bruce,

I'm not sure why Package Manager is having trouble with your filenames/ 
directories.. I'll try to see if I can figure that out, however I do  
know it's possible to have PackageManager run scripts after the files  
are extracted. Maybe a little python script could just "fix things up"  
afterwards. I'll try to look into that as well.

I'm not working from a command line; I have no experience with that. I'm 
using PackageMaker. So I don't know how to answer your questions.

[Visualpython-users] Mac help?

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

I hope someone with Mac experience can help me. I've prepared an 
installer for a significant update VPython 5.3 but am unable to make an 
installer for the Mac.

Thanks to Kadir Haldenbilen, VPython 5.3 provides extrudable 3D text of 
any True Type font, which is very cool. This requires some extra modules 
beyond numpy, and these should be included in the installer for ease of 
use. Each of these modules has a folder of .py files plus an egg-info 
file that needs to be at the same level as the folder. In PackageMaker I 
list the egg-info files as usual, but alas PackageMaker creates an 
installer which when run places these egg-info files inside folders with 
the same name as the egg-info file, minus  the ".egg-info" extension. 
This doesn't cause problems with numpy, but with one of the other 
modules it causes Python to fail to find modules inside the module folder.

I of course Googled a bit without finding any information on this. It's 
frustrating that in PackageMaker I give a destination like 
.....site-packages/xxx.egg-info but it goes into 
.....site-packages/xxx/xxx.egg-info. Experimentally, if I move the 
egg-info file up one level, VPython 5.3 works fine. I cannot find any 
switches in PackageMaker to prevent this bizarre behavior. I also tried 
chmod-ing the egg-info files to match the permissions on the numpy 
egg-info file, but that didn't help.

AAARRRGGGHHH!!! HELLLLLLLP!

[Visualpython-users] Boost bug not fixed in Ubuntu 10.04 beta1 (Lucid)

[Gary P. <gar...@gm...>]

Vpython installed from repository segfaults, as is does in 9.10.

I've filed a bug report to python-visual and libboost-python, but
perhaps we can be a squeeky wheel and get this fixed before the
scheduled April 29 release of 10.04.

To test this without screwing up my system I installed Kubuntu on a
USB drive and booted from there.

[Visualpython-users] py2exe and vpython

[Greg S. <sw...@la...>]

Dear Stef, and others,

When I explicitly include the tga files as data_files in my setup.py 
module for py2exe, it works ok when one of the py2exe options is
"skip_archive":1
In this case, the library.zip is not created, and the three tga files 
appear in folder ...\dist\visual.

However, just omitting that "skip_archive" option, thus trying to get 
everything into library.zip, makes a MyProgram.exe which fails with 
the following log:
Traceback (most recent call last):
   File "MyProgram.py", line 6, in <module>
   File "visual\__init__.pyc", line 77, in <module>
   File "visual\ui.pyc", line 3, in <module>
   File "visual\materials.pyc", line 151, in <module>
   File "visual\materials.pyc", line 129, in loadTGA
IOError: [Errno 2] No such file or directory: 
'C:\\DOCUME~1\\092710\\MYDOCU~1\\python\\dist\\library.zip\\visual/turbulence3.tga'
In this case, py2exe has put the tga files in dist\visual again, 
instead of in dist\library.zip\visual.
Manually adding the tga files into library.zip\visual does not fix 
this traceback report.

If I explicitly try to have setup.py's data_files put the tga files 
into "library.zip\visual", py2exe complains "could not create 
......\dist\library.zip: cannot create a file when that file already exists.

Any ideas?
Thank you,
Greg

[Visualpython-users] vpython 5 and py2exe

[Greg S. <sw...@la...>]

Has anyone gotten vpython 5 to work with py2exe's library.zip?  The 
three *.tga files are causing trouble.

(I put a more complete description of this on vpython.wikidot a 
couple weeks ago, but thus far no response there.)
