Hi Robert, I was just trying the PolytopeIntersector using the WINDOW CoordinateFrame. Reading the comments in the header file, window coordinates are to be specified as a clip space cube. I've seen different conventions/definitions for clip space coordinates, which ones do you mean? I'm basically performing box-selection by rubberbanding a 2d rectangle on the screen which returns pixel coordinates.
Regards, Chris I've looked at the following for reference: http://www.cs.fit.edu/~wds/classes/graphics/PTOC/ptoc/ptoc.html On 11/8/06, Robert Osfield <[EMAIL PROTECTED]> wrote:

There is an new osgUtil::PolytopeIntersector that support intersections with points. I have extended it to support intersections to triangles and lines yet but this will probably come, albiet later in the month.
