Hi, I have just attempted to install VPython 6.0.2 on a Intel Core I7 MacBoook Pro running Mac OS 10.8.2 and get a message shown below: --------------------------------------------------------- Python 2.7.3 (v2.7.3:70274d53c1dd, Apr 9 2012, 20:52:43) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "copyright", "credits" or "license()" for more information. >>> ================================ RESTART ================================ >>> Traceback (most recent call last): File "Untitled", line 1 from visual import * File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/visual/__init__.py", line 1 from .visual_all import * File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/visual/visual_all.py", line 1 from vis import version File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/vis/__init__.py", line 3 from .cvisual import (vector, dot, mag, mag2, norm, cross, rotate, ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/vis/cvisual.so, 2): no suitable image found.

Thus, the "visual" help item on VIDLE'S help menu also fails. Finally, I also use Enthought's Python distribution for scientific computing. Could these interfere with each other? Can Visual Python be installed within Enthought's distribution? I think Enthought uses a Numpy 1.6x. Regards and thanks for all your work! Adam Hausknecht Professor Adam O.

Message-ID: <93C...@sa...> Content-Type: text/plain; charset=iso-2022-jp Hi, I have been using Vpython on Windows 7 and XP machines, either with EPD(enthght python disribution) and Pythonxy distribution. It is amazing. Then I installed Vpython(Ver 5.74 for win32 on python2.73) on an windows-8 tablet (ASUS ME400c, Atom Z2760, 2GByte memory). However, it does not work. The "Vypthon" window opens but it hangs up. Does anyone know how to do with it? I keenly would like to show the physical simulation to students on my physics lecture. Thanks in advance. ---------------------------------------------- Shin-ichiro Tanaka "?????"

Because there are no torques acting on the book, the (vector) angular momentum does not change, but the (vector) angular velocity does change, and the visual effect is that the book tumbles in an unexpected way. You can see this effect in the real world. Try flipping a book or a tennis racket in the air. You'll find that if the object rotates around its long axis or the axis perpendicular to the largest side, the rotation is stable. If however you flip it around the third axis, no matter how carefully you try to flip it exactly around that axis, you'll see that the object tumbles. Bruce Sherwood P.S. Steve Spicklemire and I believe that we're very close to the next release of the wxPython-based VPython 6. All that remains is some documentation and some cleanups of keyboard issues. -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 3 Date: Wed, 6 Feb 2013 15:48:46 -0800 (PST) From: Joel Kahn <jj...@ya...> Subject: [Visualpython-users] (no subject) To: "ari...@su..." <ari...@su...>, "do...@do..." <do...@do...>, "vis...@li..." <vis...@li...>, "con...@gl..." <con...@gl...>, "sta...@op..." <sta...@op...>, "dr...@us..." <dr...@us...>, "ca...@us..." <ca...@us...>, "us...@ip..." <us...@ip...> Message-ID: <136...@we...> Content-Type: text/plain; charset="us-ascii" http://trainer.com.pa/wck/yvylzm -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 4 Date: Sat, 9 Feb 2013 23:24:42 -0700 From: Bruce Sherwood <Bru...@nc...> Subject: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities To: vpusers <vis...@li...> Message-ID: <CAFDG03jfZib4CRw2_-yXZc3K_wvLyq0ii3s=Nmh...@ma...> Content-Type: text/plain; charset="utf-8" Now available on the download pages at vpython.org is VPython 6.02, the product of a collaboration between Steve Spicklemire and me. This version is based on the cross-platform library wxPython. It has two powerful new features: (1) You can put a VPython 3D display in a window that also has wxPython buttons, sliders, etc. that have a native look and feel on all platforms. See the new example program widgets.py. (We haven't experimented with automatic layout mechanisms provided by wxPython, which may require some revision of the new VPython.) (2) In addition to the existing ways to handle mouse and keyboard events, there are powerful new "callback" mechanisms for handling events. Among much else, this provides a way to catch keyboard release events, which some users have wanted for a long time. Our experience so far is that existing programs will run with VPython 6.02, unless there is an animation loop that does not contain a rate() statement (which is now obligatory), and if you import graph or controls or filedialog you must first import visual or vis. We encourage you to try your programs and provide test cases that do not run properly even after making these two adaptations. There is one known bug with old programs, which is that materials.rough and materials.marble do not display correctly on a Macintosh, and the cause is currently unknown. There is one known bug with new programs, which is that pull-down menus (a new feature made possible thanks to wxPython) do not work on a Macintosh. This problem is partly understood, but there isn't yet a fix for the problem. There is a likely bug on Linux, in that wxPython does not currently report window metrics such as the height of a menu bar. For that reason, at the moment these metrics are hard-coded and are likely to be wrong for some Linux or some window manager on some Linux. Please let us know about your experience in this regard. Bruce Sherwood P.S. At the start of every semester there is a big spike in VPython installer downloads due to the start of classes in which VPython is used. Last month there were about 10,000 downloads, and there were considerable charges for excess data transfer from the vpython.org web site. For that reason, the installers have been moved to sourceforge.net, which provides free downloads for open-source projects like VPython. -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 5 Date: Sat, 9 Feb 2013 23:29:31 -0700 From: Bruce Sherwood <Bru...@nc...> Subject: Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities To: vpusers <vis...@li...> Message-ID: <CAF...@ma...> Content-Type: text/plain; charset="utf-8" I should add that VPython 6.02 works with 64-bit versions of Python on all platforms.

The wxPython developers are actively working on a version for Python 3.x, but I don't know when it will be available. -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 7 Date: Sun, 10 Feb 2013 23:59:58 -0700 From: Bruce Sherwood <Bru...@nc...> Subject: Re: [Visualpython-users] VPython 6.02 with buttons, sliders, and new event handling capabilities To: vpusers <vis...@li...> Message-ID: <CAF...@ma...> Content-Type: text/plain; charset="utf-8" My mistake. I had misunderstood the status of the "Phoenix" project, a rewrite of wxPython that can be used with Python 3. I just now tried using the Phoenix version, and after some very minor changes just about everything but labels worked (and that's probably easy to fix).
