Hi Dave, i don't understand what you are doing. Do you like to get a surface point back? Do you like to get a line intersected point back. Do you like a point inside the model back. So one technique is the line intersection. You define a line segment by a starting point and a ending point, then let intersect this with the scene As result you get back all intersections, and then you can decide wether the point is on the line and has intersected with the models surface or not.
may this short answer help you, may not. /adegli 2007/8/15, Dave Pugmire <[EMAIL PROTECTED]>: > > Hi, > I need to determine the following. Given a 3D point, which models > contain the point.
