[Visualpython-users] success on OS X!

[<hea...@ct...>]

Goo Morning.

I am finally able to compile, install, and use VPython from OS X. My systems are 
running OS 10.2.6, Fink 0.5.3, Safari 1.0, Apple's X11 Beta 3, VPython installer 
version 2.1.102--30709, and the December 2002 Apple Dev Tools. There is a 
note on the Fink home page regarding the recent update to the Dec. 2002 Dev 
Tools. Apparently there are problems with gcc 3.3. Here are some additional 
instructions that I feel should be placed on the OS X page at VPython.org.

- After installing Fink, Gtk+, and Python22, make sure the Fink packages 
autoconf2.5, automake, automake1.6, numeric, and pkgconfig are installed 
too. 

- Before issuing the "./configure --prefix=/sw" command, place the following 
lines in your ~/.cshrc file:

  setenv CFLAGS -I/sw/include
  setenv LDFLAGS -L/sw/include
  setenv CXXFLAGS $CFLAGS
  setenv CPPFLAGS $CXXFLAGS
  setenv BROWSER open

The first four are needed so that the compiler can find Fink's gtk and OpenGL 
libraries. The last environment variable is needed so that invoking help (by 
pressing F1) from inside IDLE_fork will work.

- Note that enabling the "root" account really isn't necessary. You can just use 
"sudo make install" and give your default admin password. Of course, if there 
are multiple users on your Mac then the first user's password should suffice 
since the first user created under OS X automatically has admin privileges.

Thanks for everyone's help!

Hi, it probably isn't possible like he said, but here is how I combined 
pygame and wxpython if it is of help:  WxPython has methods for 
communicating safely between threads, wxPostEvent and wxCallAfter.  I'm 
using them to combine PyGame and wxPython.  I start up PyGame in its own 
thread (similar to the 2nd example here: 
http://wiki.wxpython.org/index.cgi/IntegratingPyGame and the 1st example 
here: http://wiki.wxpython.org/index.cgi/LongRunningTasks ).  When my 
pygame drawing code needs to read or set the value of a wxPython 
control, it uses wxCallAfter (actually, I have my own InvokeLater and 
InvokeAndWait methods like Java: 
http://java.sun.com/products/jfc/tsc/articles/threads/threads1.html ).

Example, instead of win.inputField.SetValue("text")
something like wxCallAfter(win.inputField.SetValue, ["text"])

[Visualpython-users] WxPython + vpython

[Bruce P. <bap...@te...>]

Another approach (that I've not tried) is possibly to set up the VPython 
program as a server and control it from another process running wxPython. 
I've written a server that uses VPython and also a VBA (from Excel) routine 
that controls the VPython display. As they are running in separate 
processes, they don't interfere with each other. (I also made the server 
routine multi-threaded to allow it to continue updating the display while 
responding to calls from VB). I've been thinking of moving the UI from 
Excel VBA (which is a great rapid prototype platform) to wxPython -- I'd be 
interested to hear if anyone knows of problems with (or has tried) the 
multi-process approach.

Re: [Visualpython-users] working visualpython + wxPython program?

[Patrick B. <pat...@sp...>]

Jonathan, thanks for the reply.

For the kinds of simple things I'd like to do, visual's 3D window 
wouldn't need to be embedded within the wxPython app, it would simply 
need to be controlled by it. Preferably in a direct manner, but it 
sounds from your answer like that wouldn't be possible either. Maybe I 
could start the visual part in its own process and communicate with it 
via a socket; maybe even just sending the visual "commands" (e.g. 
"cylinder(axis=(5,0,0), pos=(3,2,1))" etc.) through the socket and 
having the receiving end just exec() them. Of course that would mean I'd 
have to learn how to use sockets ;) ...

Re: [Visualpython-users] working visualpython + wxPython program?

[Jonathan B. <jbr...@ea...>]

The short answer is "That's not possible," at least not with any
assurance of safety.  The long answer is that visual uses its own event
loop to asynchronously cache and process things like keyboard presses
and mouse clicks & drags.  Changing this behavior to say, embed a
vpython window within some larger python GUI program (using pyGTK or
wxPython or tkinter for examples) will require a mechanism to provide a
widget to visual that gives visual the necessary functionality.

That ability to write a new toolkit-specific widget in python and pass
it to visual is not possible right now.  However, it is top on my list
of things to do with the new Boost-based interface that is cooking in
CVS.

[Visualpython-users] working visualpython + wxPython program?

[Patrick B. <pat...@sp...>]

Hello,

I've been playing with the visual module for a couple weeks now--first 
off, let me just say, great work! It's great to have a way to cook up 
simple 3D displays without worrying about the low-level details. I would 
even recommend it to colleagues who are starting to learn Python (makes 
for more interesting "hello, world" programs).

My question (request, really) is, could someone post a simple example 
program that uses both visual and wxPython? Searching the archives I 
found some references to this being possible, but my own initial 
attempts always seem to result in some kind of clashing of the main 
loops of wxPython and visual; things like:

GLib-WARNING **: g_main_iterate(): main loop already active in another 
thread

Now, I'm really just starting with wxPython so perhaps the answer is 
really simple; if so just a pointer in the right direction would be fine...

Thanks,

Okay this finally worked. I added these env variables to my .cshrc file as described 
on the Fink site. Now visual will build for me without hard coding the locations of 
the headers.

BTW, the OS X install instructions on vpython.org should reflect the fact that there 
are a few other libs needed other than those that come with Gtk+ and Python22 
installed by Fink. There should also be mention of these env variables that need to 
be set on OS X. As soon as we figure out the web browser thing that should be 
added too.

Re: [Visualpython-users] finally success...but...

[Jonathan B. <jdb...@un...>]

Sorry, I was thinking bash shell rather than C-shell.  This worked fine
under tcsh:
setenv CPPFLAGS -I/sw/include
./configure --prefix=/sw
make
without having to explicitly change the header files.

Just changing CFLAGS doesn't neccesarily help you here, since this is a C++
program and is not really all that sensitive to CFLAGS.  CXXFLAGS ( C++
flags) and CPPFLAGS (C pre-processor flags) are the real keys for this
package.

Regarding the help browser, there is a trigger that we can change in our
idle_VPython for the
webbrowser documentation.  Try changing the value of help_url in
idle_VPython/EditorWindow.py to
/sw/lib/python2.2/site-packages/visual/docs/index.py.  But, that will
probably not be enough.  idle_VPython opens a webbrowser using the built-in
module "webbrowser".   In webbrowser.py there is a list of available
browsers listed under the section commented as "Platform support for Unix"
and you can probably add support for the new browser that way.
The Python-MAC SIG might have some better advice though.

...this didn't work. The shell interpreted CPPFLAGS=-I/sw/include as a

[Visualpython-users] Re: [VPython] config.log and others

[Jonathan B. <jbr...@ea...>]

Now that I think about it, I think that we did something non-standard to
install our copy of gtkglarea, and it ended up under /usr/local instead
of /sw.

Try running configure like this: "CPPFLAGS=-I/sw/include ./configure
--prefix=/sw"

If that works, we will either change the documentation or the
configuration scripts.

[Visualpython-users] make can't find header files

[Joe H. <hea...@vn...>]

Hi All.

Mac OS X, 10.2.6, December 2002 dev tools.

After discovering some problems with my Fink installation, I 
reinstalled Fink 0.5.3 from scratch. I also installed Python22, Gtk+, 
and all of the other packages I had previously installed, including 
gtkglarea. I'm using the very latest Mac OS X installer dated 9 July. 
The problem is that make is complains about the absence of certain 
header files that ARE there. I can see them. As per the instructions, I 
did "./configure --prefix=/sw" followed by "make". Configure "sees" the 
header files as far as I can tell. I'm at a complete loss here. Anyone?

[Visualpython-users] still can't compile under Mac OS X

[<hea...@ct...>]

Hi.
I'm trying to compile Visual 2.1.1 under OS 10.2.6 with Fink 0.5.3. Doing "./
configure --prefix=/sw" produces no errors. When I issue "make" the process 
bombs with the following:

[Joe-Heafners-iBook:~/visual-2.1.1] joeheafner% make

The gtkglarea.h file IS present in /sw/include/gtkgl/ so I just tried hardcoding 
that path but make then complained about the absence of another header file, 
which is also present. It's like my header files can't be seen by make or something. 
I'm thinking about trashing my current Fink installation and starting over. I 
originally installed 0.5.1 and upgraded (without any visible errors) to 0.5.2 and 
then to 0.5.3 but apparently some things didn't get updated properly. Any 
suggestions?

[Visualpython-users] Stereo

[Bruce S. <bas...@un...>]

New installers for Windows and Unix/Linux/MacOSX at http://vpython.org.

Thanks to Hugh Fisher, there is now support for true stereo video by 
setting scene.stereo = 1 on machines with suitable hardware. Hugh has 
tested this on Windows but not on Linux, and I don't have appropriate 
equipment yet (but I intend to get an appropriate graphics card and 
shutter glasses to see this for myself).

There is one slightly loose screw: On Windows, setting scene.stereo = 1 
on nonstereo hardware is essentially ignored, but on Linux this gives an 
OpenGL error (can't initialize the device). I'm inclined to think that 
it would be better to ignore the setting if the device can't give true 
stereo, since then the program would at least run (in nonstereo mode).

Here is the documentation contributed by Hugh and incorporated into the 
online reference manual:

stereo

Stereoscopic option; scene2.stereo = 1 will render alternating left 
eye/right eye images for viewing through shutter glasses if the graphics 
system supports quad buffered stereo. It not, setting the option has no 
effect. See also eyesep below. This is not a physically accurate 
virtual-reality type display. Some tinkering with the field of view, 
range, and eye separation values is usually needed to get the best 
results. (Quad buffered stereo is only available on specialised graphics 
systems that have the necessary hardware and shutter glass connector, 
such as SGI machines and PCs with nVidia Quadro or 3DLabs Wildcat 
graphics cards. It generates the illusion of depth by rendering each 
frame twice from slightly different viewpoints corresponding to the left 
and right eyes. Special shutter glasses are synchronised with the 
alternating images so that each eye sees only the matching frame, and 
our brains do the rest. It's called 'quad buffered' because there is an 
OpenGL buffer per eye, both double-buffered for smooth updating.)

eyesep

The eye separation distance in meters for stereoscopic display, ignored 
if scene.stereo = 0. The default is eyesep = 0.01, increase or decrease 
as necessary for your particular scene and camera settings.

No, he told me he's not quite ready to have his points object installed. 
It is somewhat similar to the curve object, but instead of connecting 
the points it just plots a point at each vertex. These points are 
essentially one pixel, always the same size no matter how you zoom, and 
with uniform lighting.

Has Shaun made all of his source available?

I happen to be interested in at least understanding his "Point" object. It
may be a good alternative for the sphere object - assumedly with
considerably less overhead - for some of what I am doing.

That is if I understand correctly that he did implement such an object.

For the moment, `apt-get install g++-3.0 gcc-3.0` and re-run configure
like this: `CC=gcc-3.0 CXX=g++-3.0 ./configure`

It seems that I broke gcc-2.95 support in a new way.  It will be
returned soon.

[Visualpython-users] Debian installation: gtkglarea is required on Unix-like systems

[<Ole...@ga...>]

Hello there and thanks to those who helped me get past=20
the first hurdle encountered when installing VPython under debian Linux.

The magic bullet was the installation of

  xlibmesa-dev (in addition to the other mesa stuff already installed)

Then ./configure completed.
However, make now complains as shown below. It has to do with g++,
But I have g++-2.95 installed and functional.
Any further ideas, please?

Cheers and thanks
Ole Nielsen

Subject: Re: [Visualpython-users] Debian installation: gtkglarea is
required
 on Unix-like systems

Hi,

I am not sure if I am the right person to say something here - first I
had basically no problems installing Vpython
on a debian testing box. Let's see -

For dpkg -l | grep gtkgl   I get

ii  gtkglarea5     1.2.3-2        Gimp Toolkit OpenGL area widget shared
libra
ii  gtkglarea5-dev 1.2.3-2        Gimp Toolkit OpenGL area widget
include
file

But I would be surprised if the difference in version number is
the origin of the problem.

Hmm, so a closer look at the configure output on my machine, which reads
 checking GTHREAD_LIBS... -lgthread -lpthread -lglib
 checking GL... yes
 checking GtkGLArea... yes
suggests in comparison with your output below, that maybe some GL stuff
is missing...
(For example I have
/usr/lib/libGL.a
/usr/lib/libGLU.a
)

These  are from xlibmesa-dev/xlibmesa-glu-dev and on my machine I have
dpkg -l | grep xlibmesa
ii  xlibmesa-dev   4.2.1-6        XFree86 Mesa development libraries
pseudopac
ii  xlibmesa-gl-de 4.2.1-6        Mesa 3D graphics library development
files [
ii  xlibmesa-glu-d 4.2.1-6        Mesa OpenGL utility library
development
file
ii  xlibmesa3      4.2.1-6        XFree86 Mesa libraries pseudopackage
ii  xlibmesa3-gl   4.2.1-6        Mesa 3D graphics library [XFree86]
ii  xlibmesa3-glu  4.2.1-6        Mesa OpenGL utility library [XFree86]

So maybe you have to install xlibmesa-gl-dev
as well  ? ((maybe you don't need the xlibmesa-glu-dev))
(hmm, and what the heck is that xlibmesa*3 stuff good for then ?? ;-)

Good, luck,

Arnd
