Hi, I am trying to get this simulation working where I have 3 walls(in the shape of a room) and a ball which bounces off them. The way I organized my scene is as follows (only considering side walls as of now):
World: leftXform centerXform rightXform each of these has a wallGeode (which is a osg::box) attached to them, and each of these PositionAttitudeTransforms are positioned and aligned accordingly. Now, to do collision detection between the Ball (which I am considering to be a point for now, and thus a line given its velocity) and the World, I'd want a way for the line to be checked against the PAT transformed Bboxes. Any suggestions on how I should approach this (any callback that I should define or what)? Also, as per the API, I can retrieve the bounding box of a Geode and bounding sphere of a Node. Thus, if I were to use the above hierarchy, I would have 3 bounding spheres for left/center/right Transform. What I really want is a bounding box for these 3, since the BS would be a very loose fit for the collision detection. So, do you recommend me organizing the hierarchy in any other way ? I would appreciate any help. ... Thank you!
