"The Bullet Physics Playground" is a Qt5 app, that allows you to simulate physics objects in an OpenGL GUI with Lua scripting. You can create OpenSCAD STL meshes on the fly, see this "Hello World!" demo * https://www.youtube.com/watch?v=WbElbcZ6Sa0 You can create gears, motors and hinges * https://www.youtube.com/watch?v=xy7qDgStMXk * https://www.youtube.com/watch?v=1sVbZWYuCGE Or simulate cars * https://www.youtube.com/watch?v=rUSo1e9c9Bg * https://www.youtube.com/watch?v=QnBYP4LF7Ww * https://www.youtube.com/watch?v=60CBUTiH1pQ Create marble runs * https://www.youtube.com/watch?v=IwdbtfiEo0A * https://www.youtube.com/watch?v=1sVbZWYuCGE There's a POV-Ray export, so you can render animations derived from your physics experiments * https://www.youtube.com/watch?v=TUtLOcbtcZk * https://www.youtube.com/watch?v=yjTmB9_mbzY * https://www.youtube.com/watch?v=LyO2PMlbjAc * https://www.youtube.com/watch?v=ckqvFCUczd0 G+ community * https://plus.google.com/communities/118046861018657351607 Gitter chat * https://gitter.im/bullet-physics-playground/bpp GitHub page * https://github.com/bullet-physics-playground/bpp The Bullet Physics Playground was tested to run on Ubuntu 14.04 and 16.04, a Windows and Mac port would be nice, feel free to contribute and give it a try. -- View this message in context: http://forum.openscad.org/The-Bullet-Physics-Playground-tp17342.html Sent from the OpenSCAD mailing list archive at Nabble.com.
