[Visualpython-users] Progress with VPython-wx

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

It occurs to me that a note I posted to the wxPython forum might be of some
interest to the VPython community:

You might like to see how far we've gotten, with lots of help from this
wxPython community. Below is a screen shot of the wxPython-based VPython
(the image of this demo came from Windows and also displays correctly on
Linux; everything but the menus works on a Mac). In the past, the 3D canvas
had to fill the window; there couldn't be other widgets in the window. In
the program, the 3D cube rotates, and the controls let you change the
color, the rotation speed, and the rotation direction, and you can also
type into the text control.

The 3D portion of the code is pretty trivial. The first statement creates a
window and the second places an OpenGL canvas in the left half of the
window. You'll note that some adjustment is made so that the canvas is L*L
but the window is larger.

w = window(width=2*(L+window.get_dw()), height=L+window.get_dh(),
title='Widgets')
display(window=w, y = 0, width=L, height=L, forward=-vector(0,1,2))
cube = box(color=color.red)

... wxPython code to make widgets for setting color, and rotation speed and
direction

while True:
    rate(100)
    cube.rotate(axis=(0,1,0), angle=cube.dir*cube.dtheta)

Of equal importance to widgets is the fact that it was possible to
eliminate very nearly all platform-dependent C++ code (there are small
instances of platform-dependent Python code, but that's trivial). The only
remaining platform-dependent C++ code is GetProcAddress. Of critical
importance is that the new VPython works on 64-bit Cocoa-based Macs,
something that was impossible with the old VPython, which was Carbon-based.

I've also run up against a significant platform-dependent display issue
which I've "solved" temporarily on one particular Linux with hard-coded
integers. The VPython API has always had the user specify the width and
height of a window as the outer bounds, so that one can easily place (say)
two windows adjacent to each other or one below the other, with the canvas
being smaller than that. I need to know the dimensions of the writable
area, but unfortunately only for Windows will wxWidgets give me the
dimensions of borders, title bar, and menu bar. For Mac and Linux, the
values are all -1. For both Windows and Mac, these values are probably
extremely stable (I use hard-coded integers for the Mac), but on different
distributions of Linux, or for different window managers on the same Linux,
I don't know how to get the dimension information I need.

Note that my problems are somewhat different from those using wxPython to
create apps. VPython is middleware; people use VPython to create apps. This
puts an additional burden on VPython to be universally cross-platform, not
just cross-platform for a particular app.

Availability note: At vpython.org one can get an experimental version of
the wxPython-based VPython, but the support for widgets isn't yet included
even in that experimental package. However, the up-to-date source code is
available at

https://github.com/BruceSherwood/vpython-wx.

The program widgets.py that generated the image is at the repository in
site-packages/visual/examples.

I'd like to try to track down those problems with 6. Can you send me an example that exhibits the trouble? Sorry for the difficulty! I recognize that it's frustrating.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Sebastian S. <sch...@go...>]

Thank you very much for providing me the binaries.

Unfortunaly, it was not compatible (I remember a libboost-x.<49 not 
found, tried to make symlinks, no luck, it doesn't start)

So I compiled wxPython and VPython6 from source.

Now my project has some view problems and the mouse-object-picking. The 
3d modell is a kind of sphere, only composed of cylinders, vectors: 
(0,0,0)-->surface of sphere

I think I have to switch back to vpython 5

Not necessarily. You're adding "Categories" to each entry, which consist
of key-value pairs. One of these categories is "Development Status",
which you can just declare to be "Alpha" or "Beta". Here's a link of one
of my projects that's in alpha to show what I mean:

http://pypi.python.org/pypi/matanui

That is certainly a problem for a fully automated process. However, I
think a bit of documentation on the PyPI entry goes a long way in
explaining that. However, you can put a dependency into the meta-data of
setup.py, which declares that as well. I can see that there's also a
2.9.x wxPython in PyPI, so it can also be pip installed *automatically*
when installing wxVisual through pip.

http://pypi.python.org/pypi/wxPython/2.9.1.1

Maybe that requires first installing the native 2.9.x wx widgets, but as
I said, a bit of documentation ...

> If I'm wrong, I think it's a great idea!

Go for it. I'd be keen to see it this way. It would open up a whole
different population of users. Additionally, the setup.py provided
meta-data can also be very useful for package maintainers of
distribution packages. Talking about distro packages: with stdeb, one
can also retrieve PyPI packages, have them automatically rolled into a
.deb package and installed, keeping the package management nice and
clean ...

Hi Guy,

That is the ultimate idea when things settle down...  I was thinking that we needed to get some more input from testers before putting anything on pypi, but I've never actually released anything there, so I'm not certain of the exact protocol. Is it not expected that most of the packages there are stable releases? The other issue is our dependency on wxPython 2.9.4. Even the wxPython folks don't have binary releases yet, and the package managers (that I've seen) are still on 2.8.x. If I'm wrong, I think it's a great idea!

If you've created the setup.py with all its magic already, wouldn't it
be worth putting that up onto PyPI [http://pypi.python.org]? This way
anybody could just install it using pip without the need to download,
etc. You can also have custom build/compile steps in the setup.py, so
that the C/C++ parts can be compiled on the target machine upon install
via pip. The PyMongo project for example has this solved really nicely,
where the pip install works smoothly, and even defaults back to a pure
Python driver in case build tools (GCC, etc.) are not available.
Obviously that fallback won't be an option here, but the pip install
magic via PyPI would step VisualPython up another notch.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[John Z. <joh...@wa...>]

Hi All,

I love all the work going on in the Wx version of VPython. I can't wait until I have some time to try it out. Just for the record, I want to point out that Sebastian's test program runs fine (no seg fault) on my 64 bit Ubuntu 12.04 that just uses the standard Ubuntu python-visual package (with the libgl-mea fix reported on the VPython download page). I am wondering if the downgrade of the libgl might also fix the problem on 12.10, but I have not yet had a chance to try it, as all my machines are on 12.04 at the moment.

--John

ps. Thanks Bruce and Steve for the rapid progress on the new VPython. This should be a real boon for the VPython community.

Subject: Re: [Visualpython-users] Seg Fault if using control-field and a box    in a scene

Hi Sebastian,

First.. everything below assumes you're working with Python-2.7.

We have also experienced trouble on Ubuntu 12.10. If you don't want to build the experimental vpython-wx from source I've built a linux .egg file and posted it here: https://dl.dropbox.com/u/20562746/VPython-6.01-py2.7-linux-x86_64.egg

You can install it using the setuptools "easy_install" command line program:

sudo easy_install https://dl.dropbox.com/u/20562746/VPython-6.01-py2.7-linux-x86_64.egg

The good news is that this will get you the latest experimental version of visual python, (which I've tested with your program on Ubuntu 12.04 anyway, and it appears not to crash) without having to build from source.

The bad news is that it depends on having wxPython 2.9.4 installed, and that probably requires building from source (see INSTALL.txt here for instructions <https://github.com/BruceSherwood/vpython-wx/blob/master/INSTALL.txt skip the part about building vpython, and go straight to the wxPython part.)

In case that's not possible, I've also posted a tarball of my wxPython libraries but there's no guarantee they will work on your system:

https://dl.dropbox.com/u/20562746/wxPython-2.9.4-linux_ull.tgz

You can install them manually if you like:

sudo tar -C / -xzvf wxPython-2.9.4-linux_ull.tgz

Of course you'll still need Polygon, TTFQuery and FontTools installed for text, etc. I'm guessing you have those around from the older vpython?

Realize that this all circumvents your package manager and may have to be undone manually if you decide you want to "go back".

If you decide to try this.. please let us know how it comes out! Sorry it's not simpler... we're working on that!

thanks,
-steve

Perhaps Steve can post something about the status of his installer.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Steve S. <st...@sp...>]

Also... for what it's worth, I've build and posted .egg files (which are easy_install'able) for Polygon, TTFQuery and FontTools here:

https://dl.dropbox.com/u/20562746/fonttools-2.3-py2.7-linux-x86_64.egg

https://dl.dropbox.com/u/20562746/Polygon-2.0.5-py2.7-linux-x86_64.egg

https://dl.dropbox.com/u/20562746/TTFQuery-1.0.5-py2.7.egg

These are built on/for Ubuntu 12.04 x86_64. They may also work on your 12.10 system.

The good news about these is that they can be uninstalled using the "pip" utility.

Enjoy! Let me know how it goes...

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Steve S. <st...@sp...>]

Hi Sebastian,

First.. everything below assumes you're working with Python-2.7.

We have also experienced trouble on Ubuntu 12.10. If you don't want to build the experimental vpython-wx from source I've built a linux .egg file and posted it here: https://dl.dropbox.com/u/20562746/VPython-6.01-py2.7-linux-x86_64.egg

You can install it using the setuptools "easy_install" command line program:

sudo easy_install https://dl.dropbox.com/u/20562746/VPython-6.01-py2.7-linux-x86_64.egg

The good news is that this will get you the latest experimental version of visual python, (which I've tested with your program on Ubuntu 12.04 anyway, and it appears not to crash) without having to build from source.

The bad news is that it depends on having wxPython 2.9.4 installed, and that probably requires building from source (see INSTALL.txt here for instructions <https://github.com/BruceSherwood/vpython-wx/blob/master/INSTALL.txt skip the part about building vpython, and go straight to the wxPython part.)

In case that's not possible, I've also posted a tarball of my wxPython libraries but there's no guarantee they will work on your system:

https://dl.dropbox.com/u/20562746/wxPython-2.9.4-linux_ull.tgz

You can install them manually if you like:

sudo tar -C / -xzvf wxPython-2.9.4-linux_ull.tgz

Of course you'll still need Polygon, TTFQuery and FontTools installed for text, etc. I'm guessing you have those around from the older vpython?

Realize that this all circumvents your package manager and may have to be undone manually if you decide you want to "go back".

If you decide to try this.. please let us know how it comes out! Sorry it's not simpler... we're working on that!

thanks,
-steve

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

[Sebastian S. <sch...@go...>]

The building process of vpython was successfull. Also my project was
running without problems. The only problem was the control window and the
box in the second scene.
If i comment the box-create line and uncomment the controls it works.
If i uncomment the the box and comment the controls line it also works.
Both lines uncomment - seg fault.
(The code is only an excerpt of my project)

Thank you for your patience and sorry for my bad english

I'll try to modify the setuptools script to work on visual 5.7x and post if I can get it to work. That may permit you to build a fresh version in your environment.

Re: [Visualpython-users] Seg Fault if using control-field and a box in a scene

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

I too find that recent versions of Ubuntu offer non-working versions of the
package python-visual, and I don't know why building a new version also
fails. Steve Spicklemire has been doing excellent work in making an easy to
use Linux installer for the new wxPython-based VPython, which is quickly
getting quite mature. Perhaps Steve can post something about the status of
his installer.

[Visualpython-users] Seg Fault if using control-field and a box in a scene

[Sebastian S. <sch...@go...>]

 Hello,
I'm new in Vpython. I have designed a 3D modell in vpython to interact with
them. The mathematics, displaying the 3D modell - all fine.

After this I wanted to make a controls-field with buttons and I always get
a segfault. After some hours I have compiled the newest vpython version
5.74 (+modules) and still the same problem.

Thank you for your help,
Best Regards, Sebastian Schleitzer

[Visualpython-users] Much simpler structure for VPython-wx

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

Steve Spicklemire figured out a much simpler scheme for VPython-wx which
eliminates the strange "double import" structure I had created, in which
you import visual, and visual imports you.

Instead, he uses the "atexit" module to define a function to be called at
the end of a Python program. That end-of-program function enters and
endless while loop containing rate(30), which keeps the graphics window
alive for zoom and spin. There is no double import.

Many thanks, Steve!

Re: [Visualpython-users] How VPython 6 differs from VPython 5

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

>From INSTALL.txt:

You need wxPython (wxpython.org). Currently one needs version 2.9, but
on Linux you need to apply a patch. Here is information about the patch:

https://groups.google.com/forum/?fromgroups=#!topic/wxpython-users/e27JioMs1fs
 In this forum post is a link to the patch, located at

http://sourceforge.net/projects/wxpython/files/wxPython/2.9.4.0/wxPython-src-2.9.4.1.patch/download

 Place the patch file in the wxPython directory, cd to that directory,
and execute this in a terminal:
patch -p0 < wxPython-src-2.9.4.1.patch

The instruction "place the file in the wxPython directory" is a little inscrutable since I didn't know off the bat exactly where that is.

also, it's usually pretty simple IMO to pull down the src packages,
say for wx-widgets, and bump the versions, instead of installing right
from source.

i havent actually used debian/ubuntu regularly in quite some time, but i think:

apt-get source <package>

...was part of the process... debian has like fifty billion helper
commands; im pretty sure the whole rebuild process was only 3-5
commands.

you probably just need the build deps, eg. header files and whatnot
usually included in *-dev packages. try:

apt-get build-dep <whatever-the-wx-widgets-package-is>

...that usually gets you 95% on the way, with the occasional rebuild

Apparently, that has to be built from source as 2.9.x is not in the 
repositories. I can do that, but I get an error message that GStreamer is 
not found. However, according to my package manager, GStreamer is 
installed on the system.

The source you need is wxPython-2.9.4.0 not 2.8. Sorry.

to apply the patch go to the wxPython-src-2.9.4.0 directory (not the 
wxPython directory that it contains) and type:

patch -p0 < path/to/the/patch/file

Let us know if that works!

Re: [Visualpython-users] Experimental Mac Installer on vpython.org, (and linux setup.py ready for testing)

[Marc B. <mbe...@ar...>]

Hi,

I'm new to vPython but I'll be giving this a go.

I've noticed that my vPython app runs much quicker on windows under the 64
python compared to 32 so I'm eager to get the mac 64 bit version to work.

Thanks for the amazing bit of programming.

VPython (5.74 and before) by eliminating nearly all platform-dependent code
and by eliminating the threading associated with rendering. This makes it
possible for the first time to run on 64-bit Python on the Mac and will
simplify maintenance and further development of VPython. It is also likely

Xcode.app, and source downloads of wxPython-2.9.4, boost, and so on. For
linux you can use apt-get (or equivalent) to install dependencies.

This makes it possible for the first time to run on 64-bit Python on the Mac and will simplify maintenance and further development of VPython. It is also likely to make possible adding standard buttons, menus, etc. to a window that contains a VPython scene.

Now, an animation loop MUST contain a rate statement, which limits the number of loop iterations per second as before but also when appropriate (about 30 times per second) updates the 3D scene and handles mouse and keyboard events. Without a rate statement, the scene will not be updated until and unless the loop is completed.
