..well..what im trying to do is basically build 3D terrain based on scanned terrain from sattelite...so I have numerical data in simple form, X,Y,Z where actual distance between closest points is 20 meters, while height vary depending on terrain config...so I have about 30x30 km scanned area /1500x1500 points, 20 meters distance between points/..I already make it work by creating specific area chunks and then move their vertexes, whats working nice..but I am not satisfied with performance since its generated output about 4.5 million polys, so I manage to get about 25 fps based on visible area of 9x9 km where user have to choose specific chunk to see...customer is very very happy, but I want it to be more optimized so I can somehow manage whole chunk /30x30km/ at one with at least 20 fps...any suggestions, appart from approach i did already??
