Re: [Visualpython-users] problem with slider

[Laney M. <mi...@co...>]

Hi Bruce,  Gary has helped me with a couple of Python questions.  Since 
you use VPython a lot, do you know how to adjust the dot size for 
vpython 2d plots.  I want to make the Mandelbrot set, which needs the 
highest resolution I can get, one pixel per dot if possible.  I think 
the control of dot size is done deep down in some library function 
called by vpython.  I was just hoping you had seen how to make that 
happen.  From within vpython, the minium dot size is much larger than 
one pixel.  Otherwise, vpython is perfect for the job.

Thanks,

Thanks very much for the clear report. It turned out that the controls 
module never had treated a nonzero minimum correctly. I sent a corrected 
version of controls.py to Leau. I will of course update VPython to 
incorporate the corrections.

[Visualpython-users] problem with slider

[leau2001 <lea...@fr...>]

Hi all,

I hve a problem with slider.
When i used one, the slider value init=0  and why not the mini i chose... ?

Program :

from visual.controls import *

c = controls() # Create controls window

def calcul (d,e):
   
    #result=int(d/e)
    print d, e
    print txt

b = slider( pos=(-20,20), width=6, height=20, min=10000, max=100000, 
action=lambda: calcul(60000,txt)) # Create a slider in the controls window:


while 1:
       
    c.interact() # Check for mouse events and drive specified actions
   
    txt=b.value
    txt=int(txt)
    print txt
    #result=60000/txt
    #print result

When you run this program like this, you see the slider value are on 
0... and the when you touch the slider a little, slider value come's to 
10000 as the min value.
But why this slider value is 0 at the beginning and not the min value ?

thx for help

Re: [Visualpython-users] VPython errors on a laptop

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

I haven't seen this before, but it would seem to be a problem with the 
video driver on that laptop. The problem is probably not in VPython but 
in OpenGL, which is reporting the error. Older laptops sometimes had 
lousy video drivers. It would make sense to try to update the video 
drivers and see whether that cures the problem.

Another thing you can try is changing the graphics acceleration setting. 
Right-click the desktop background, choose Properties, then Settings, 
then Advanced, then Troubleshoot.

[Visualpython-users] VPython errors on a laptop

[Jody E. <jod...@ho...>]

Greetings,

I'm a fairly new user to VPython, but somewhat experienced with general 
graphics & 3d related things.

Here's an issue that's just cropped up for me when using the graphing module 
of VPython:

***VPYTHON RENDERING ERROR*** ../../vpython/src/gldevice.cpp:940 invalid 
enumera
nt when rendering OpenGL display list number 520
***VPYTHON RENDERING ERROR*** ../../vpython/src/gldevice.cpp:940 invalid 
enumera
nt when rendering OpenGL display list number 521
***VPYTHON RENDERING ERROR*** ../../vpython/src/gldevice.cpp:940 invalid 
enumera
nt when rendering OpenGL display list number 522


and so on until infinity, repeating that exact same line.   It is only doing 
it on a laptop (sorry, not my laptop - so I don't have specifics) ... the 
program has been run on several desktop machines with no issues.

However, the graphs display just fine on the laptop -- it just keeps 
cranking out that error message.


We do have a small 3d graphing module in the pipeline as well, and while 
this error is harmless (but very annoying) right now, I'm somewhat worried 
that it will become a show-stopper with the 3d module.

Has anyone seen anything of this sort before, or know what might be going 
on?   The version of VPython being used is the one on the vpython.org 
website, downloaded in the last couple of weeks.

My first guess is that the laptop doesn't have a 3d accelerator.   It's 
undoubtedly just a stock card with no bells & whistles, but shouldn't that 
just all get shunted over to software rendering by OpenGL anyways?

The laptop is running Windows XP, and Python 2.4.2.   The various desktop 
machines are mixed Windows & Linux, with no apparent problems.


Thanks in advance for any help/advice/suggestions!

Version 3.2.6 for Windows and Linux: Corrects an error in the plotting 
of the last portion of a many-point curve (introduced in version 3.2.4). 
Curves with more than 1024 data points are now rendered by 1024

Re: [Visualpython-users] Strange curve behavior

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

It's my fault. I was trying to fix a problem with curve plotting and 
introduced a different bug, which is sometimes worse than the old bug.

The problem I was trying to fix was that when you drew a very long trail 
following an object you might see a sizable gap between the last point 
of the curve and the position of the object. This was due to not 
rendering the last point of a curve when displaying every Nth point 
(only 1024 points are rendered). Alas there are now cases of which you 
found one where the cure is worse than the disease. I'll either retreat 
to the earlier version or do a better algorithm which I've worked out 
but not coded in C++, which is to not skip a constant N points every 
time but step N-1, or N, or N+1 along the way to spread out the missing 
points, and end on the endpoint.

[Visualpython-users] Strange curve behavior

[Matthew K. <mko...@ma...>]

I know that "curve" has a history of behaving strangely when too many 
points get appended, but I've encountered a weird behavior I don't think 
I've seen before.

A trail is being appended that tracks a moving object.  After a short 
time, the trail stops appending, and a straight line segment is drawn 
from the last appended point to the current position of the moving 
object.  This continues for a while, then the curve is suddenly updated 
to include all previously undrawn points, and the weird "connecting line 
segment" behavior starts again.

This is hard to describe in words, so I've posted a movie of it.  The 
movie file is 1.3 MB and is in Windows Media format.  Download the file at:

http://www4.ncsu.edu/~makohlmy/curve_bug.wmv

The code that generated this output is attached.  Note the behavior 
starts after about 1000 iterations. (In this program, deltat is one day, 
loop stops after 6 years, behavior starts about halfway in, or 
3*365=1095 iterations.)  So I don't think this is a case of too many 
locations appended.  I've certainly seen past student programs that have 
much larger trails than this that display perfectly.

System specs:
Windows XP SP2
AMD Athlon 64 3200+, 2.0 GHz, 1.0 GB RAM
Video:  GeForce 6200 TurboCache, PCI Express x16, 256 MB
ForceWare version: 81.98

Video drivers are up to date.  Turning off hardware acceleration does 
not fix the problem.

Any ideas? (Apologies if this has already been reported.)

Reading between your lines I think you already know this, but:
Quantian ( http://www.quantian.org ) has it.   I tried VPython from 
Quantian once, and there were problems.  YMMV.

You might be able to figure something out using VMWare Player.  I really 
don't know what would be possible in your case; you'd have to dig around 
yourself.   VMWare Player runs virtual machines on Windows and linux 
hosts.  You can have a linux VM on a Windows machine, or vice versa.  I 
run Ubuntu on a WinXP machine.  I can tell you that it works perfectly.  
It's really amazing.  I have yet to find a limitation.  Running full 
screen, it  behaves *exactly* like a native Ubuntu.

VMWare Player is free.  They sell software that *makes* VMs, but the 
*player* is free ... like Adobe Acrobat / Acrobat Reader.   But VMWare 
maintains a collection of pre-built virtual machines, including a Ubuntu 
machine.  Installation is sickeningly easy.  Python comes 
pre-installed;  VPython was a snap to add.  It works perfectly.

You might have to install VMWare player on WinXP as Administrator, which 
may be a problem for you.  But the Ubuntu VM can live on a USB drive.  
That's how I do it.

http://www.vmware.com

Ubuntu itself can live on and be booted from USB drive.  See 
http://ubuntuforums.org/showthread.php?t=75439 Some work required.

I bought a 20 GB laptop drive on eBay for $30, and an enclosure for 
$10.   The whole thing is just slightly larger than the drive itself.

How about Knoppix, and install the additions you need on a USB stick?  
I've thought about this option, but never tried it.

RE: [Visualpython-users] vpython with knoppix/slax/etc

[Arthur <ajs...@op...>]

There is a Knoppix distribution called LiveZope that includes Vpython

ftp://math.cgu.edu.tw/pub/KNOPPIX/

I have not tired it.

[Visualpython-users] vpython with knoppix/slax/etc

[Eric A. <Ay...@ma...>]

Does anyone know of a linux-on-CD distro that runs vpython? If so,  
which one? How well (if at all) does it work?

It  would be very helpful to me if I could run linux with vpython off  
a bootable USB thumb-drive, due to the nature of the "smart  
classrooms" that are being forced upon us by the campus. I haven't  
built my own Knoppix variant before, though, and would prefer not to  
duplicate the effort if it's been done already.

Thanks,
-EA

No - scene.exit was fixed.  We believe that having idle exit after the
vpython program exited was an artifact of the way that the user starts
up idle.  See Bruce's mesg "Re: [Visualpython-users] Re: horror story"
in the archives, on 07 Dec, 2005.

VPython (or any other program, for that matter) cannot ever kill the
calling process by accident.  ipython is choosing to exit after the
VPython script is done.

[Visualpython-users] vpython 2.3.5 stil crashes calling script

[Flavio C. <fcc...@gm...>]

Hi,

I thought I herad someone sayng that the bug that caused vpython to crash
the calling python application when you close its window was solved for
verision 2.3.5.

I Would like to say that I still have that problem not only in my own app,
which opens a vpython window., but I also observed this behavior when I
opened a vpython window from ipython and when I close the vpython window it
kills ipython.

I am on Linux (gentoo), using python 2.4.2 and vpython 2.3.5

thanks,

[Visualpython-users] VPython crashes with 06_spectrum.py

[Joe H. <hea...@ct...>]

When I try to run the VPython program 06_spectrum.py, which is  
included in the M&I instructor resources, the program crashes. I'm  
including the crash log here in the hopes that someone can at least  
help me decide whether the bug lies in Python 2.4 or in Visual. I've  
built VPython from the latest Fink packages under Mac OS X 10.4.4.  
The same bug appeared under 10.4.3. My apologies for the large amount  
of text.

It is built as an extension module and shipped with a default Python
install.  You might use it to build multiplatform GUI programs with
tcl/tk.  However, based on the atrocious look of Tcl/Tk on my Linux
machine, I would personally develop using PyGTK or WxPython.

The default working directory for IDLE is set in the shortcut properties
(I think).  The shortcut shipped with VPython is set to the examples
directory, but you should be able to change it to whatever you like.

PYTHONPATH (in all caps) is not related to Python files in exactly the
same way as PATH is related to executable files.  PYTHONPATH only
affects module import statements, not the search path for Python
scripts.  In all cases, C:\Python24\python.exe only takes an argument to
the file to be run itself; it does not search a list of directories to
find the file.

[Visualpython-users] re how to set "pythonpath"

[Laney M. <mi...@co...>]

Thanks to several people who responded.  From you responses, I can see 
that I didn't do a very good job of framing my question. 

Here's the situation.

This is windows xp with python 2.4 and visual python installed in 
C:\python24.  The python runs fine.  To run any of the examply *.py 
files that come with vpython, all I have to do is click file open and 
find the example files located in a subdirectory of c:\python24. 

Now I have several previously written *.py files in a directory that is 
located far from (many clicks away inside the python file open dialog 
box)   What I  really want is to have it so that when I click file open, 
I am already in that directory of mine (the one far removed from 
C:\\python24.  In microsoft word and microsoft excel, there is a dialog 
box in which one can make exactly that setting.

Assuming I cannot do that setting in python, my next preference to have 
is the one I was trying to describe earlier.  I want to fix it so that 
if I type myfile.py from the command line and that myfile.py is in my 
remote directory, that the python will open my file withouth a thousand 
clicks.  I assumed from my reading that onee makes an entry to the 
"pythonpath" variable exactly as one used to do under dos.  From the dos 
prompt, type "path" and the contents of the path variable are 
displayed.  Any modifications are made by adding onto the path statement 
in the autoexec.bat file.

Now in windows xp.  I can't even find the autoexec.bat statement (which 
actually is a dos thing).  I can't find any windows equivalent of 
autoexec.bat or of the path statement itself.  The python books and the 
online docs make reference to a "pythonpath" statement.  It is that 
statement I'm trying to find.  If in python idle, I clice file path 
browser, I get a dialog box that makes a list with about 6-8 lines with 
each line clearly describing a search path.  I am assuming that it I 
need to add my distant directory to that list.  Only I can't figure out 
from the documentat where that list resides, where is comes from, or how 
to add to it. 

I know I am missing some major obvious point that is so fundamental that 
it is hard to address, but still I am in the situation of having to go 
though about 8 clicks *every* time I want to open a file in my own 
directory where my *.py files are located.

Thanks to every and sorry about not giving enough information to make my 
question clear.

See the documentation for sys.path.

Environment variables are a feature of your operating system, not Python
itself.

[Visualpython-users] pythonpath question- how to set it

[Laney M. <mi...@co...>]

I need to add to the search path with the IDLE uses so that I can run 
some py programs from a directory of mine.  I can find a display of the 
search path under "file, path browser" but I cannot find in the 
documentation anywhere how one can add to this list.  Searching the doc 
files I easily find a reference to environment variables, but I cannot 
find any descriptin that I can actually understand how one actually sets 
environment variables.  I am supposing that setting or adding to the 
*.py search path is what the term "environment vars" is referring to.

thanks
