Dear ng, first of all thanks for the support for my last questions!
I try to get a scene snapshot into a numpy array. In pure OpenGL I used a QT or glut context and glReadPixels and converted that to a numpy array using scipy. My problem on osg is that the context seems to be deactivated after a viewer.frame() call - glReadPixels returns only zeros. So I guess either I need to keep the context active, reactivate it, or register a callback somehow in a post render phase (?). Furthermore, if I want to use the osg method with a camera-attached osg.Image, I'll need to convert the Image.data() to numpy format. Has sb got an idea (or even a code snippet) that would work in osgswig? Thanks a lot! Mathias _______________________________________________________________________ Jetzt 1 Monat kostenlos!
