        <div>it is for simulation, i have a moving entity and a terrain
          (with buildings etc). Now I am not after triangle level
          intersection, but after Entity BBox collision with the terrain
          (enough is true false). I was thinking to do it really very
          simple by having LOS rays from the entity center to the
          corners of the BBox. The entity can move in any direction</div>
      </div>

    May the standard manipulators are a good start. Some of them perform
    collsion detection. A number of LOS-intersectors will do the job,
    too ;-)<br>
    <br>
    Cheers<br>
    Sebastian <br>

              <br>
              basically this is not an easy task. What exactly do you
              expect as a collision result? <br>
              I've implemented a triangle-box collision with MTD
              (minimal transform distance = vector describing how to
              push the box to get it exactly away from the colliding
              triangle). OSG has all the math facilities to do this, but
              I guess you'll save a lot of headache using pyhsics etc.
              for dynamics. So maybe try to explain the problem you're
              trying to solve a bit more in detail.<br>
              <br>
              Cheers<br>
