Re: [Pyode-user] Pyode binary distribution

Hello,

First thing you should check:
Do the examples from C:\Python26\pyode-examples run correctly?

tutorial3.py has an example with a GeomPlane some falling boxes and spheres.
Does it run correctly?

I have just tested it with a fresh install of Python 2.6, PyOpenGL 3.0.1 and
PyODE-snapshot-2010-03-22.win32-py2.6.exe.
It worked from the first try.

Which version of ODE do you use on Python 2.5? It seems that different ODE
versions behave slightly differently
with the same scene description.

Do you use PyODE directly from your program or do you have some higher level
library, like cgkit?
In the second case, please check that it uses the same stepping method (step or
quickStep) in both Py25 and 26.

Can you send me a small test program, with the floor and one body, which works
in Py25 and not in 26?

I am also using PyODE in a simulation which involves bodies sitting, and
sometimes falling, on the ground.
When the gravity, body mass or vertical speed were too high, they could break
the floor and fall down.
So you may start debugging with reducing the gravity value.

However, the simulation runs exactly the same in Py25 and 26, with exactly the
same code. I do not use
PyODE directly, but all the rendering and simulation is done using cgkit. I'm
using boxes and trimeshes,
and sometimes spheres for debugging.

The program in which I use PyODE is a robot arm simulator, still in early stages
of development, available here:
http://github.com/alexdu/robot-sandbox . For now, it only runs on Windows out of
the box (unzip and run).
