We have separate geometries for both LINE and FILL (Each one can be dynamically turned off and both can be on at the same time). So, we need not to switch between these modes. We are using polygon primitives because we need to support object selection in the application (using LineSegmentIntersector). Is there any way, I can select polygons drawn as Line loop primitive.

But, it is producible with other nvidia cards like Quadro 5000 or GF 310M. I have tried using the same driver version on nvidia machines. Do you need to dynamically switch between PolygonMode LINE and FILL, or are you always doing LINEs? Because you could try using a Line Loop primitive instead of polygons. > Has anybody faced similar issue? Any help in this regard will be grateful. I have no experience with this. I know the Quadros have different line-drawing code in their driver, because line-drawing performance is one place where all the money you pay for a Quadro actually makes a big performance difference. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
