Re: [osg-users] Collision Detection and getting intersection point between two object
Hi, I really want to use Bullet library but before proceeding forward I have some question so that I don't face problem in future :- 1.Can OsgBullet integrate with my current application ? 2.Does OsgBullet give me list of intersection point where two object node meet ? I need Intersection point for generating texture coordinate of composite model(by joining two basic model), then Parameterization of Triangulated Surface Meshes(Composite model) and then texture mapping . I have never use bullet engine so please help me . ... Thank you!

Re: [osg-users] Collision Detection and getting intersection point between two object
1.Can OsgBullet integrate with my current application ? I don't know about the specifics of your application but I for one am using osgBullet in it's current form to compute collisions in several of my programs. 2.Does OsgBullet give me list of intersection point where two object node meet ? Yes. Regards, Kim.

The Bullet API already provides one or more contact points when two collision shapes meet. You'd have to study the Bullet API to determine if this meets your requirements, but it sounds like what you want. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Collision Detection and getting intersection point between two object
Hi, I'm working on problem in which user develop composite shape like building , hut , table etc. by arranging basic shape like cylinder,cube,hemisphere etc. using picking operation. Right now basic shape overlap each other , which is not required in my application . Therefore I need collision technique to avoid these overlap . I also need corresponding set of intersection point where two object intersect during collision. So here are my questions : 1. How to perform collision in OSG ? any tutorial 2. How to get Intersection point where two object meet ? Can somebody please help me regarding this ... Thank you!

Hi, Osg dont have this features, you should use another libraries for this (like physics simulation libraries).

Try osgBullet: http://code.google.com/p/osgbullet/ I'm using it for collisions.

I am planning to do some significant work on this project later in the year, including breaking out the dependency on the collision and dynamics libraries so that osgBullet can be used for collision-only. This should be done by the end of the year (sorry -- lots of other work in the queue ahead of this). -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
