Dear Leo, You might find this useful, http://www.lfd.uci.edu/~gohlke/code/transformations.py.html It's transformation mathematics using numpy with compilable C extensions for additional speed.

The code is open source, so feel free to use whatever portion of it you find useful. However, since the utility functions are integrated into a larger package you would probably find it more useful to look specifically for a 3D utility package.

I've been having trouble installing on a rocks linux cluster. Is there a way to compile *only* the utility functions? e.g. rotate, projection, etc. All I need are the 3D transformation functions, I don't need the graphical functions. |

Hi Bruce , I see the web page http://antarktikos.wordpress.com/2010/05/15/how-to-compile-vpython-5-on-fedora/ and I have no idea what dependencies is missing . I'll keep trying.

Since the build fails in the link phase, presumably some dependencies have not been installed.

I had a similar problem.

There are two different issues. If you see a display with incorrect colors, that usually means that it is necessary to update the graphics driver. If you have trouble in a 64-bit environment but not in a 32-bit environment, that indicates a problem with building the application for 64-bit environments. If you installed the standard python-visual package that comes with Ubuntu, that could mean that the package was not built correctly for 64-bit Ubuntu. If you built from source, there are in the mailing list archives notes by people who have successfully built for 64-bit Ubuntu.

it turns out it also works on by 64bit, but the colors are different, to the point that the settings make it impossible to see the ball (and an gyro display thing i'm trying out) on the 64bit, but you get it nice and clear and colorful on the 32 bit...

Hi, i'm having some problems with python-visual. i've attached two example codes i found on the web. pyCube works ok, but ball appears for a moment and then only a black window is shown. i tried it on two other ubuntu computers, both 32 bit, and it worked ok... the cube worked ok on my 64bit ubuntu 10.10. any clues? thanks! -- Rodrigo. |

Due to some major restructuring that's going on, the example of a JavaScript+WebGL version of the VPython demo program doublependulum is no longer working at http://tinyurl.com/684xldd. Instead, use this link: http://tinyurl.com/633acxv Bruce Sherwood |

Occasionally users of VPython have expressed interest in displaying
VPython animations in a browser. Unfortunately, Python doesn't run
in a browser, but something related is in the works.
David Scherer, the creator of VPython, and I are working on making it
possible for VPython-ish programs to run in a browser window. Recently
many browsers (all the major ones other than Internet Explorer)
include WebGL, a graphics library similar to the OpenGL library used
by VPython. JavaScript programs can drive WebGL, in a browser.
Here is an example of a JavaScript+WebGL version of the VPython demo
program doublependulum:
http://tinyurl.com/684xldd
This JavaScript program looks very similar to the original program and
would look even more similar were it not for the fact that among the
features not yet implemented is the frame object. If the frame object
were implemented, this JavaScript program could have been created
almost entirely by using an automatic converter program I've just
written (in Python). In the absence of this project, the
doublependulum program would include a ton of extremely arcane
JavaScript code, just as VPython is supported by a ton of arcane C++
code.
What's the point of this? Well, for example, you may know
there's an ebook version of the intro physics textbook "Matter &
Interactions" written by Ruth Chabay and me. Both Wiley and we want
eventually to add interactive features such as animations, and it
seems likely that would/should take place in a browser, in particular
because (as you'll see in the demo mentioned above) one of the
strengths of this approach is that there can be text and other
standard browser elements on the web page in which the animation is
embedded. Ruth and I would like to be able to use our suite of demo
programs, and write additional ones, without killing ourselves in
minutiae.
We do NOT think that this is a replacement for VPython, and for
student use in intro physics. Python is a much more mature and cleaner
language than JavaScript, and Python has the blessing of computer
scientists, so for both technical and political reasons Python is a
far better choice for introducing computational physics than is
JavaScript.
Scherer solved two unsolvable problems to get to the point we've
reached after a few weeks of work. Unlike Python, JavaScript does not
support "operator overloading", in which you can for example change
the meaning of the operator "+" so that 2+3 is 5 but vectors v1+v2
have their individual components added. Nevertheless, by a clever
approach Scherer has made it possible to add and subtract vectors, and
multiply by scalars: v+v, v-v, s*v, v*s.
The second unsolvable problem is that a JavaScript+WebGL program has
to be "event-driven", with the program divided into pieces to be
called by the web page manager. This requirement means that a
straight-forward orbit program will run through an entire loop before
the web page ever gets updated, so you only see the final state, not
the animation, and if the loop is an infinite loop you never will see
anything. Scherer found a tool named "streamline" that will take a
non-event-driven JavaScript program and automatically convert it to an
event-driven JavaScript program. The only burden on the programmer is
that instead of including, say, rate(100) in a loop (to iterate only
100 times per second), you have to include rate(100,_), where the "_"
is a signal to the streamline engine where it can break the loop
contents into a separate routine that is called 100 times per second.
(We intend to change the signal "_" to something meaningful, like
"wait").
You can also in this environment write true event-driven programs, but
we feel strongly that this style of programming is not where the
novice should start.
Stay tuned!

P.S. At the moment, the tinyurl above will work on Chrome on Windows
and Mac and Linux, and on the WebKit version of Safari on the Mac (a free
download that enhances Safari). It should also work on Firefox but
doesn't at the moment, though it has in various past versions of the
project so I expect it will eventually work again.
P.P.S. The attentive reader will have noticed that I didn't reveal the
name of this project. That's because we haven't yet thought up one
that David, Ruth, and I are happy with. Suggestions welcome!

I don't understand "If you just try to install visual, it will try to install its own numpy". On Linux, visual doesn't install numpy, you have to install numpy as a dependency before building visual.

A few years ago, I built the visual module on top of the enthought distribution I had downloaded. I did this so students in the class I was teaching could just download one distribution plus one patch from me in order to have everything we needed.

As you said, I tried cube's origin in pyramid's rotation. The issue is
solved, thank you very much.

------------------------------------
Objects other than curve, convex, faces, and points can be rotated
about a specified origin (to rotate these other objects, put them in a
frame and rotate the frame).
obj.rotate(angle=pi/4, axis=axis, origin=pos)
The rotate function applies a transformation to the specified object
(sphere, box, etc.). The transformation is a rotation of angle
radians, counterclockwise around the line defined by origin and
origin+axis. By default, rotations are around the object's own pos and
axis. There are no defaults for the extrusion object, and one must
specify all parameters: angle, axis, and origin.

Hai,
I'm new to vpython. I've two objects, a cube and a pyramid. After
changing the position of pyramid from its origin, could you tell me how
to rotate both objects combined? I tried
cube.rotate(angle=45, axis=(0,1,0))
pyr.rotate(angle=45, axis=(0,1,0))
But it's rotating on two different axis of its on. I would like to have
something like two objects sticked together and having rotation.
Could you please help me to do so?
Thanks in advance.
Kind regards,
Ershad K
