Thanks for all the inquiries regarding pythonCascade. I could spend a little bit more time with testing recently and examined more than 10 packages. Pythonizer successfully built the following packages that contains near 300 Python modules. AlenImage: all the 19 modules Aspect: all the 69 modules gp: all the 35 modules Graphic3d: all the 73 modules Image: all the 24 modules MFT: all the 8 modules OSD: 4 modules Quantity: all the 11 modules Standard: 3 modules TCollection: all 11 modules TColQuantity: 1 module TColStd: 5 modules TShort: 1 modules WNT: all the 24 modules This is a huge project so this doesn’t mean that each and every method in each and every class from the picked packages was tested. But the picked methods seem to work fine. I will try to release the first beta as soon as I can, hopefully still in August or September.
