Hi! Milton, Ronie and I had a very fun programming session. Here some random screenshots during our programming session. Igor, would it be possible to have in the same window Athens and OpenGL? Maybe the question does not make sense, just I prefer the ask. On some point we would like to some popup in 2D above a 3D scene. All the examples are available on: http://smalltalkhub.com/#!/~ronsaldo/roassal3d You need to download first NBOpenGL to play with Roassal3d Cheers, Ronie, Milton & Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
