Hello Pygame users and developers ! Is there a way I can speed up the transfert from a surface to an OpenGL texture ? Right now, I use the pygame.image.tostring function, but it seems like converting the pixels to a Python str creates a serious bottle neck in my stop motion application...
I think that it should either be implemented directly in Pygame, (best option) or done using something like ctypes in my application. If none of these option is not easy enough, I am thinking about switching to Gstreamer+GTK with the GdkPixBuf, instead of Pygame surfaces. An other option would be to rewrite the whole application in C++... Any suggestion to fix this in a way that is not too long ? My frame rate drops to 4 FPS when there are more than a few surfaces in my list. Please try Toonloop to test this out. It works well on Linux. If someone get it to work on Mac or Windows, I would need hints for packaging it for those OS too. I convert the surfaces to OpenGL texture in texture_from_image from the file http://bitbucket.org/aalex/toonloop1/src/tip/toon/draw.py on what is currently the line 42. -- Alexandre Quessy http://alexandre.quessy.net/
