Hi,
We started using processing as a learning tool in one of our classes. http://fr.flossmanuals.net/processing/ch007_les-formes  is use as one of the support material.
The issue we have is when trying to render some basic 3d object with the sphere() or box() functions (see below):
  - processing logs says that "smooth level 2 is not available. Using 1 instead"
  - the resulting image has glitches (see attached image)



We're running processing on Windows XP with a fairly recent Intel HD 2500 graphics card and the latest intel drivers.
Would you please help us workaround this issue :-) ?

Thanks !
