You don't really need a another library to workout the distance between 2 geodes or points It's a straight forward calculation.
Simple get the positions of the geometries center or collision points distance = sqrt( square( start[0] - end[0] ) + square( start[1] - end[1] ) + square( start[2] - end[2] ) ); Depending on the collision detection you want, simple isector collions works and is quite fast and provide in OSG See the exmaple for various different methods Now if you want geometry to geometry collison detection then you will need to handle that either your self or through some 3rd party code -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mrs. Mister Sent: Monday, May 05, 2008 12:23 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Collision detection and Distance measuring in OSG hello, i want to do collision detection and distance measurung in osg between geodes. can someone advise me to a library which has been prooved with osg. so that i can start up working. i just tried SWIFT++ (http://www.cs.unc.edu/~geom/SWIFT++/) which can handle distances. but the source is very old and a "make" doesnt compile without own chnages of the swift++ source. it compiles, but the program segfaults in the swift library. now im stuck. i did: tesselate geodes and get a array of vertices of triangles. this i fed into the collision/distance library to use their functions. maybe someone has an idea. bye henry _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
