Re: [osg-users] How to grasp an object in virtual scene by using a CyberGlove and OSG?

Hi Junjie, I don't think there is anything related to physics and collision detection in OSG, you might want to look at physics engines like ODE or Bullet and integrate them in your application. There are things like osgODE and osgbullet out there, but I don't know about their status or if

Yes, osgBullet does have a collision-only library. I just wanted to provide additional information, as the O.P. seemed unaware of osgBullet and what had already been done there. On Sat, Aug 3, 2013 at 3:35 AM, Jan Ciger jan.ci...@gmail.com wrote: I think that what Robert meant was to simply

Hi Junjie, The OSG doesn't have general collision support, it only provides line segment and polytope intersectors that probably aren't what you are looking for. You are problably best looking at a dedicate collision detection and perhaps physics library to handle this side of things. For

There was some development in osgBullet for grappling with a data glove and hand model. Without haptics, the user had no feedback over how tightly the objects were grasped, and Bullet had difficulty resolving the constraints in this situation. We found a better approach was to detect gestures

Hi, I am working on a virtual assembly demo by using OSG and CyberGlove together. Currently i have sucessfully connect and drive the virtual hand in the scene using realtime data sent from the glove. Now i want to add collision detection between the hand and a part in the scene. when the
