[Pharo-users] OpenGL project

Hi, I would like to do a bit of OpenGL in Pharo, but it does not seem to work at the moment. Tried NBOpenGL with a spur image (50560): _ fails at installation from configuration browser (need to click again on installing to get all classes) _ demo "GLTTRenderingDemo new openInWorld" fails at NBGLContextDriver with error "No suitable implementation found for initializing OpenGL context for your platform" (running on a Mac) Tried with a pre-spur image (50496): _ same weirdness at installation _ demo fails at NBGLCurveRenderer with "MessageNotUnderstood: receiver of on: is nil" Is there a working demo available out there? I have worked a lot with OpenGL ES 2.0 and could definitely provide work on the topic. Cheers, Thibault
