Dear pythonOCC users,
Here is a short development status after a couple of days of silence on
this ml.
- the OCAF missing modules (XCAFApp, XCAFDoc etc.) have been wrapped.
The complete OCC Application Framework should now be usable from python.
I attached a very basic sample to show how to use. A few more samples
are planned for the next days,
- I tried to include within pythonOCC a python wrapper for the Salomé
Geometry modules (see http://sourceforge.net/projects/salomegeometry).
This work is still very experimental and for Windows users only (didn't
manage to compile salomeGEOM on Linux platform). The Salomé GEOM API
offers a high-level topology/geometry layer combined with
parametric/associativity feature and could be of interest in pythonOCC.
The complete Salome GEOM API is 9 more modules. It's disabled by default
in the environment.py script (line 34: WRAP_SALOME_GEOM = False ).
- the __hash__() overload feature (also know as list/dict pythonOCC
feature), suggested by Frank Conradie, now works for both
Windows/Linux/MacOSX platforms.
This work is available on the SubVersion repository (svn rev.232). A
prebuilt binary was compiled for Windows-Python25 and can be downloaded
from the URL: http://www.pythonocc.org/Releases/daily/ .
Note that the current development status is close to the upcoming 0.2
release (except the scons script that is not up-to-date with recent
modifs) and should be considered as a "Release Candidate". Please report
any bug or weird behaviour.
Best Regards,
Thomas
