Fine so far. > 3. Pull the resulting list of normals from the GPU. Good lord, why? You're going to USE them on-GPU aren't you? Pulling them back across the bus could be very slow and expensive. You should be able to do what you're looking for on-GPU. There are some cache and read/write issues when you need to write to a data store and then immediately read it back and use it for drawing. Others can comment on that. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging. OpenGL. Scene Graphs. GIS. GPS. Training. Consulting.
