Sorry if it bothers anyone, but I was not sure that this question made it to the list... so here goes again: Hi, I've been using picking in order to retrieve the coordinates of individual quads in an indexedQuadArray. Below are the results of 2 different "picks", showing the VWorld coordinates and local coordinates of the intersection using pickIntersection.getPointCoordinates() and PickIntersection.getPointCoordinatesVW(). Also shown are the coordinates of the quad's vertices. The vertices have been checked and are correct. The VWorld coordinates are also correct, but the local intersection coordinates are a bit out to lunch. As you can see, the coordinates don't even fall within the boundaries of the quads that were picked. Further, once the calculated local x coordinate falls outside the coordinates of the shape, the shape is not pickable. This leaves about 3/4 of the quads in the Shape3D unpickable. Has anyone used this, or can anyone offer any advice as to what might be happening? I think clearly there is a bit of a mismatch between local and world coordinate systems, but what can I look into to find the root of the problem.
