Hi all, I'd like to include a key/legend in a plot generated by vpython. What's the easiest way to set this up? I realize that one can specify a few comments in the title='some title text' gdisplay argument, but I'm trying to illustrate a figure with 6 lines, comments about which won't fit in the title bar.

I'm sure that would work... however, I've had serious trouble with fink in the past where I didn't *realize* it was being used to resolve various dependencies and then someone without fink could not run an app I had built due to shared libraries being linked in without my knowledge! I guess I know just enough to be dangerous.. ;-). Anyway.. I guess I'd say we might use fink to sort out how to build something (e.g., boost) but it would be best, in the interest of building a truly stand-alone library, to avoid building with fink enabled (i.e., after running /sw/bin/init.sh). Of course.. all IMVHO. ;-) -steve On May 6, 2008, at 12:10 PM, Bruce Sherwood wrote: > We can use fink to get packages we need for BUILDING Visual, as > long as we can incorporate static libraries so that a user doesn't > need fink. > > Bruce Sherwood > > Sent via BlackBerry by AT&T > > -----Original Message----- > From: Steve Spicklemire <st...@sp...> > > Date: Tue, 6 May 2008 11:13:03 > To:Martin Costabel <cos...@wa...> > Cc:Steve Spicklemire <st...@sp...>, Bruce Sherwood > <Bru...@nc...>, Hugh Fisher > <hug...@an...>, visualpython- > us...@li... > Subject: Re: [Visualpython-users] Help with Boost on Mac OS > > > Hi Martin, Hugh, Bruce, etc... > > Forgive me if I'm not thinking about this right... but for a new > native/carbon build I'd think we'd want to steer clear of fink as > much as possible.

You can always repeat manually what Fink does. Most of a Fink package description is just a short documentation of the steps necessary to get the sources, patch them and build and install the package. You can use the experience and information contained in the package description to build things yourself. Of course, this goes both ways: Once you manage to create an aqua version of vpython, I will probably try to make a Fink package of it, because I consider Fink also as a convenient all-purpose package manager. I consider typing a single command "fink install visual-py25" simpler than reading and following any instructions to download and install a package, even if it exists in the form of a dmg with precompiled binaries in it. -- Martin |

Hi Martin, Hugh, Bruce, etc... Forgive me if I'm not thinking about this right... but for a new native/carbon build I'd think we'd want to steer clear of fink as much as possible. I got the impression we were trying to make a completely stand-alone vpython that doesn't require any fink, not even for libraries/etc... I got boost to build OK in /usr/local/ with fink "turned off". I guess the next step is to try to get some of vpython to compile and link against those header files and libraries? -steve On May 6, 2008, at 10:47 AM, Martin Costabel wrote: > Bruce Sherwood wrote: >> Note in the CVS file MAC-OSX.txt (which is somewhat out of date) >> these >> comments, which may or may not be relevant to your problem: >> >> Before making a change to src/Makefile.in, I got a message about >> possible mismatch of versions, >> as though when I build against /sw/bin/python2.5 and then run >> /sw/bin/python2.5 the system thinks >> these are different pythons.

In the meantime, I found the right flags. The current Fink boost1.34 (or 1.35) libraries work for me with vpython (3.2.9 or also 4beta24), using the dynamic library. -- Martin |

Note in the CVS file MAC-OSX.txt (which is somewhat out of date) these comments, which may or may not be relevant to your problem: Before making a change to src/Makefile.in, I got a message about possible mismatch of versions, as though when I build against /sw/bin/python2.5 and then run /sw/bin/python2.5 the system thinks these are different pythons. Martin Costabel commented: "I am getting this, too, when using the dynamic boost-python library, but not with the static libboost_python-mt.a. This is certainly a bug with the libboost_python-mt.dylib, but I haven't yet found a combination of build flags to build it correctly, in particular in a way that would also work on OSX 10.5." Following his suggestion, I put Mac-specific code into src/Makefile.in to link to these other libraries. But then I got this error message in the link phase of the make: /usr/bin/ld: table of contents for archive: /sw/lib/libboost_python-mt.a is out of date; rerun ranlib(1) (can't load from it) So I executed ranlib /sw/lib/libboost_python-mt.a, redid the make, executed make install, and it worked.

You can install boost (versions between 1.32 to 1.35) via Fink. Boost1.34 is used for building vpython (the released X11 version) with Fink. -- Martin |

Hi Hugh, I haven't had a chance yet to work on the vpython/boost stuff, but I did get boost to build on Mac OS. Finals are almost over, so I hope to jump in with you soon! Can you compile the example program here: http://www.boost.org/doc/libs/1_35_0/more/getting_started/unix- variants.html It worked for me with the following command line: c++ -I /usr/local/include/boost-1_34_1 example.cpp -o example good luck! -steve On May 6, 2008, at 4:49 AM, Hugh Fisher wrote: > > I'm just starting to fill in the stubs for my native Mac > OS Carbon version of VPython, which in turn seems to be > triggering previously hidden Boost errors.

I'm just starting to fill in the stubs for my native Mac OS Carbon version of VPython, which in turn seems to be triggering previously hidden Boost errors. Things like bool check() const; in boost/python/extract.hpp are being reported as errors by Xcode 'doesn't declare anything' I downloaded the Boost 1_34_1 sources and bjam, did a bjam build and then bjam install. If that wasn't enough, I have absolutely no idea how to proceed. Can anybody point me to either a nice prebuilt installer for Boost on MacOS, or at least some detailed instructions on pitfalls and how to avoid them? -- Hugh Fisher DCS, ANU |

I've never used py2exe, but I'll note that you have "from numpy import
*" in your program, and you specify "numarray" as a needed package,
whereas the production version of VPython depends on Numeric, not numpy
nor numarray (it's supposed to work with either Numeric or numarray, but
I think it doesn't actually work with numarray).

Does anyone could help me generate an executable program that functions for the bounce.py with py2exe?
Thank you
bounce.py:
from visual import *
from numpy import *
ball = sphere(pos=(0,4,0), color=color.red)
example = zeros((10,10),dtype=float)
print (example)
setup.py:
from distutils.core import setup
import py2exe
opts = {
'py2exe': {'packages':['numarray']
}
}
setup(windows=[{"script" : "bounce.py"}], options=opts)

Hi Martin, Have you seen the paper by Noah Finkelstein and colleagues, "When learning about the real world is better done virtually..." ? In case you have not, you can find it in volume 1 of Physical Review Special Topics - Physics Education Research. It's the third article at: <http://prst-per.aps.org/toc/PRSTPER/v1/i1> The paper looks at students setting up electric circuits, in which the group who used the Phet simulation Circuit Construction Kit subsequently does better at setting up real circuits than another group who had previous experience with the real components. By the way, I would also be very interested in seeing a list of other papers on the topic of the effectiveness of computer modeling - thanks! cheers, Andrew Duffy Department of Physics Boston University |

Hi Folks, I have been having students use Vpython for about 7 years or so in my intro engineering physics courses. The course is structured around several major projects which contain a computational modeling and visualization component. I am giving a workshop on Project Based Learning in Physics featuring VPython from an implementors perspective. (For more info see http://www.physicsworkshops.org/PBP/index.htm) Basically, when you leave the workshop you should have the tools to implement computational modeling projects in your classroom. I am looking for papers/studies that address the effectiveness of computational modeling/visualization in enhancing student learning. While I have pre and post tested my population with the FCI for five of the past eight years, my course is too non-traditional to say anything specific about computational modeling. Looking through the TPT archives doesn't seem to turn up anything. I know Bruce and Ruth put out an article in the AJP this month. (In fact this months issue is all about Computation) Can anyone point me to other sources? Thanks! mmason ------ Martin S. Mason Professor of Physics and Engineering Mt.

Pretty slick! And a very nice way to give an overview of the capabilities (in MandiPy, uncomment the long sequence at the end of the file and then run it). I don't understand the Retardation program. Why isn't there electric field everywhere, not just in the forward direction? Was the proton supposed to be in uniform motion and we just start looking as it's passing the origin? Why don't I see a "pancaked" electric field distribution?

Good afternoon. I've been working on a toolbox of helpful snippets that I eventually (next year) plan to introduce to my introductory physics students. I've used this toolbox to make what I intended to be a simulation of the electric and magnetic fields of a moving charged particle, accounting for retardation. The toolbox is called MandiPy and I'm attaching it to this message. I'm also attaching the actual simulation, Retardation.py. I've scoured the Internet for examples of such a simulation in source form and have found exactly nothing! The closest thing I've found is a Java implementation in An Introduction to Computer Simulation Methods, 3rd edition by Gould, Tobochnik, and Christian (Pearson/Addison-Wesley, 2007). It's a fine book but Java and I don't get along well at all. I'd appreciate feedback! Joe |

It looks like your problem might be a simple typo. There should be TWO minus signs before prefix: .... --prefix=/usr/local. That this might be your problem is suggested by the fact that in the output you show, there is a reference to /usr/lib/libgtkgl.so instead of /usr/local/lib/libgtkgl.so, despite the fact that you were aiming at /usr/local.

I wrote the script for a student, a few years ago. I admit there are a lot of stuff in it, not directly related to your problem (the annoying thing is to program the different trajectories and camera positions with a good timing to get a smooth movie). In fact, you only need to use povexport() function to export a VPython scene to a pov script, then run povray on it. If you do this for several pictures, then you just display them at 15-20 fps, and you have your movie ;) I will try to extract a little example from the big script... ------------------------------ Message: 5 Date: Fri, 18 Apr 2008 16:46:34 +0930 From: Symion Subject: [Visualpython-users] new web page To: vis...@li...

The information, though, is almost two years old. If we dig a little deeper, I see that this method required patching ffmpeg to create an X11 grabber. Now, as you might expect, grabbing from X11 is a native part of the latest releases, so just go straight to the documentation for how you might pull it off: http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC4 Is this useful?

Jaap, I'm not sure what you mean by "out of date"...the link opens fine for me again today when I retried it... The information, though, is almost two years old. If we dig a little deeper, I see that this method required patching ffmpeg to create an X11 grabber. Now, as you might expect, grabbing from X11 is a native part of the latest releases, so just go straight to the documentation for how you might pull it off: http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC4 Is this useful? (I have just started to work with ffmpeg for other purposes, but I'm not a frequent Linux user, so my insights are limited). Bill > William C.
