PyOpenGL plugin
For my custom-node learning exercise I hacked out a plugin for writing custom nodes in Python with PyOpenGL. Not too pretty, but it hardly ever crashes Vizard anymore. :rolleyes:
In case anyone's interested... |
Sweet!
Does the custom node call a specified Python function from inside the draw method? If so, you will need to make sure the plugin acquires the Python global interpreter lock before triggering the Python code. This might be the cause of the crashes you mention. Example: Code:
PyGILState_STATE pyGILState = PyGILState_Ensure(); |
Yes, I've got all the Python calls properly wrapped in GIL Ensure()/Release() calls. I'm somewhat familiar with the Python C API (I did most of the work on the Python bindings for Syzygy, with SWIG and more recently SIP), but I find it so verbose and tedious that there's a strong temptation to be sloppy about validating the results...I think I've got it fixed up now...
