hello, I tried the same program on another system today, which should be faster than the system I used yesterday (faster processor, Intel instead of AMD, faster (external) graphics card), but it seems to be about twice as slow as my yesterday system. On that theoretical faster but in practice slower system, indeed the performances are about equal for VP3 and VP5 ??? cheers, Stef Stef Mientki wrote: > hello, > > sorry for reacting so late, > but the core of my VPython wrapper was under construction. > > Strange, but despite all the positive sound about speed of VPython-5, > I've the opposite experience, Vpython-5 is often 30% slower than Vpython-3, > I wonder why I seems to be the only guy experiencing that ? > > I limit the fps at 50 fps. > and here are the measurements (all programs found on the web): > > VP3 VP5 Program > 50 30 Cherry tree > 50 30 Clock > 15 10 Fountain > 15 10 Alfabet > 50 35 Pipes > 50 50 Multi-Pendulum > 48 48 ODE > 48 48 Double-Pendulum > 50 35 Mandelbrot Visual Part takes 12Sec/VP3 15Sec/VP5 > > cheers, > Stef > > Gary Pajer wrote: > >> I've finally upgraded to 5.0 on my XP machine. >> >> I have a subjective sense that it might be slower than 3.0.

hello, sorry for reacting so late, but the core of my VPython wrapper was under construction. Strange, but despite all the positive sound about speed of VPython-5, I've the opposite experience, Vpython-5 is often 30% slower than Vpython-3, I wonder why I seems to be the only guy experiencing that ? I limit the fps at 50 fps. and here are the measurements (all programs found on the web): VP3 VP5 Program 50 30 Cherry tree 50 30 Clock 15 10 Fountain 15 10 Alfabet 50 35 Pipes 50 50 Multi-Pendulum 48 48 ODE 48 48 Double-Pendulum 50 35 Mandelbrot Visual Part takes 12Sec/VP3 15Sec/VP5 cheers, Stef Gary Pajer wrote: > I've finally upgraded to 5.0 on my XP machine. > > I have a subjective sense that it might be slower than 3.0.

Here is (hopefully) the final update to the symChess program. A couple of bugs fixed but decided not to include sound effects, too distracting. Source code for Symion Chess v1.03 symchess.py <http://home.primusonline.com.au/knoware/python/symchess.py> Symion |

Following a suggestion from Bruce Sherwood I changed the line class display( visual.ui.display): to class display( visual.display): in the file vpyframe.py which can be found in the pygeo folder. Now my pingpong project works again. Depending on your computer you might want to change the time step parameter dt (increase the value of dt to speed up the ball). Poul Riis |

Hi, I have downloaded the new version of vpython and have the recommended python release. When I run Symion's chess I am now getting a runtime error from M/soft Visual C++ runtime library. Runtime error! Program: C:\Python25\pythonw.exe. This application has requested the Runtime to terminate in an unusual way...... I am running python / vpython on Windows XP Any ideas? Thanks, Tim |

A quick somewhat uninformed guess is that it should just be class display(visual.display) but I'm not sure. I'm a bit surprised to see something like visual.ui.display in a user program. Certainly not documented. Bruce Sherwood Poul Riis wrote: > I just tried to rerun an old (rather crazy) project of mine (attached - > I'm sorry that names and comments are in Danish).

I just tried to rerun an old (rather crazy) project of mine (attached -
I'm sorry that names and comments are in Danish). Even if it used to run
it now gives an error message:
Traceback (most recent call last):
File "C:/Python25/Lib/site-packages/visual/examples/pingpong.py", line
6, in <module>
from pygeo import *
File "C:\Python25\Lib\site-packages\pygeo\__init__.py", line 3, in
<module>
from pygeo.vpyframe import display
File "C:\Python25\Lib\site-packages\pygeo\vpyframe.py", line 38, in
<module>
class display( visual.ui.display):
AttributeError: 'module' object has no attribute 'ui'
My guess is that there is a compatibility problem with Visual 5 and PyGeo.
Can someone confirm that?
If yes, is there a workaround or shoudl I just reinstall Visual 3?
If no, what else could be the problem?
And btw, Symion, this file includes a small example of the use of winsound.

I'm guessing you're running the program on the older Visual 3, where this did indeed give an error. There's a "singularity" in the up direction. What Visual 5 (the new version) does is that whenever the program tries to set scene.forward and scene.up to be in the same direction, it nudges scene.forward ever so slightly away from scene.up. Since scene.forward only affects a human's view of the scene, this causes no trouble.

I just picked copied the source code for your chess game, but when I ran it, got the error -
Traceback (most recent call last):

Any ideas why this is happening? |

Here is the latest update for The Symchess Game. It now has all the pieces in the right position and I have implemented the End of game exit conditions! i.e take your opponents King! and press Enter to stop the clock! This takes you to the clock statistics page, which is printed into IDLE window. Source code for the latest 3D chess game symchess.py <http://home.primusonline.com.au/knoware/python/symchess.py> Next I think I will go straight into 3D Galaxians. Does anyone know how to make Sound in python? Symion |

I have found the previous version of symchess has become unstable. In the middle of a game, I noticed the processor fan was racing, even though I wasn't doing anything or had any background applications running. Then the game froze and a non-response error appeared in the window title. This happens whenever I run that version of symchess. Here is the source code symchess_bug.py <http://home.primusonline.com.au/knoware/python/symchess_bug.py> The reason seems to be the addition of an extra window for clock output, this seems to have destabilized it. Here is a version that does not open any extra window, it is stable so far, as I have been playing a lot of chess lately it seems to be standing up well. It has the clock displayed in the Same window, with Enter key still used to change player control. It also has a statistics report and Time play analysis at the end of each game. Note: you have to actually take your opponents king and press Enter to activate The End Game routine.

I am trying to build visual python 5.0_candidate, on a linux
Ubuntu 8.0.4 (hard heron) laptop. I corrected an end-of-scope
problem at the end of render_manager.cpp (shown here:
-------------------------------------------------------------
*** src/core/util/render_manager.cpp.ORIG 2008-04-08 11:24:36.000000000 -0700
--- src/core/util/render_manager.cpp 2009-02-12 16:21:56.000000000 -0800
***************
*** 58,61 ****
return interval;
}
! } // namespace cvisual
\ No newline at end of file
--- 58,61 ----
return interval;
}
! } // !namespace cvisual
-------------------------------------------------------------------)
then got a complaint about the mutex_t type not containing a lock:
= - = - = - = - = - = - = - = - = = - = - = - = - = - = - = - = - = = - =
../../visual-5.0_candidate/src/core/util/render_manager.cpp:37: instantiated from here

= - = - = - = - = - = - = - = - = = - = - = - = - = - = - = - = - = = - =
I haven't been doing any development in this environment, so I hope
there is a simple answer to what may be going wrong. I have attached
config.log and build.log, as requested in the make output.
I am using the "threadpool-0_2_5-src" threadpool source; I pulled
that down over a month ago, but I'm not sure whether that is the
right package. There are lock definitions in, e.g., the
/usr/include/boost/thread/detail/lock.hpp file, so there is the
possibility of picking out a lock definition. There was some
discussion in some file about which threadpool version to get for
use with visual python 5.0, and as I recall it wasn't totally
specific. So if this is just the wrong package, that would be an
easy answer.
Thanks for any help.

The following code produces a complete lock out of my system!
from visual import *
scene.fullscreen=True
scene.visible=True
sphere()
while 1:
if scene.mouse.events>0:
m=scene.mouse.getevent()
break
scene.visible=False
wmax=scene.width
hmax=scene.height
scene.fullscreen=False
print wmax,hmax
Run the code, click on the sphere and it should return to IDLE window.
Instead the whole screen stays blank, the sphere controls freeze and esc
does not restore control back to windows.
Also, alt+tab does not work either! So I can not flip to other applications.
For some reason I can recover control by typing (into a blank screen)
scene.visible=1<enter>esc
This is typed into IDLE window, other wise I have to Turn Off my
computer the hard way.
Does anyone else experience this or is it just my old graphics card?
I am running Vista Home Premium

Possible. But I've switched first from spheres to cubes. I needed that as I wanted to give them individual colour to see where in colour space they'd be located (my application computations are 3D to 3D colour adaptation transformations, and that gets quite messy, so position in space were the first 3D coordinates, colour tuples represented the second/target 3D coordinates). But for my own purposes I can get away with rendering points, for publications then I'll have to go and code up a histogrammer that will aggregate voxels to 3D "summary" objects for rendering. > This is a good example of how very specific > applications can be either faster or slower.

Ah. I think it is the case that the Visual 5 spheres are rendered more carefully than those in Visual 3 (whose spheres often looked a bit angular), so I can imagine that with a very large number of spheres there would be a penalty. This is a good example of how very specific applications can be either faster or slower. Bruce Sherwood Guy K.

I'm using VPython to visualise results of numerical simulations and computations with potentially thousands to 100s of thousands objects. So for some I've switched from rendering spheres to points which hugely improved performance again. But I guess my use case is less usual, so it may very well be that for "normal" use cases 5.0 is faster than v 3. Guy -- Guy K.

Lots of tests I've run show the two versions to be about the same speed, but in some cases 5 is faster than 3 (due to subtleties in going from Numeric to numpy for array support). A good way to test is like this: from time import clock t0 = clock() ..... t0 = clock()-t0 print t0 Bruce Sherwood Gary Pajer wrote: > I've finally upgraded to 5.0 on my XP machine. > > I have a subjective sense that it might be slower than 3.0.

I've finally upgraded to 5.0 on my XP machine. I have a subjective sense that it might be slower than 3.0. Before I try to reinstall 3.0 to check, I thought I'd ask ... What's known about the speed of 5.0 vs 3.0 ? -Gary |

Now if you go to vpython.org you're taken directly to the Visual 5 portion of the site (you may have the old home page cached, in which case you'll need to refresh the browser page). The following has been added to the new home page: "If you are new to VPython, it is recommended that you use this new Visual 5 which has enhanced features and improved documentation. If you have been using Visual 3, you should know that this Visual 5 release candidate does not yet support two features available in the older Visual 3: handling right-button and middle-button clicks and drags (other than user rotation and zoom), and scene.cursor.visible. Note too that Visual 5 uses the currently supported numpy array module, whereas the older Visual 3 uses the Numeric array module, which is no longer supported. For further details, see What's new in Visual 5." The switch was prompted by the very low level of bugs reported, and the fact that a large class at NCSU has been using Visual 5 on Macs for several weeks with no problems. Bruce Sherwood |

You can simply assign the sphere object to a variable and reference it
later. e.g.:
from visual import *
ball=[]
for i in [0,1]:
s=sphere(pos=(0,i,0), radius=0.1)
ball.append(s)
while True:
if scene.mouse.events:
m = scene.mouse.getevent()
if m.pick is ball[0]:
ball[0].color = color.red
if m.pick is ball[1]:
ball[1].color = color.blue

I am trying to get around the problem of sphere object being unindexable.
I need to make spheres appear, positioned according to some list, for
example:
for i in [0,1]:
sphere(pos=(0,i,0), radius=0.1)
Is there any way of making these different spheres behave differently
without using indexing?
For example, I would like to be able to make the lower sphere go red
when it is clicked on, using this fragment of code:
while True:
if scene.mouse.events:
m = scene.mouse.getevent()
if m.pick is ball[0]:
ball[0].color = color.red
But obviously it won't work because I haven't named it ball[0]. I can't
figure out a way to name the objects based on their position without
using indexing. Is there any way to do this?
Thank you.
