How heavily reduce geometry for Orthophoto?
« on: May 02, 2013, 10:15:59 AM »
Hello everybody,

I am still working on my first test with PS and I have created a 38Mio Face geometry of a 85*170 m urban area an now want to create an orthophoto. Are there any rules on how to decide on the number of faces I should have in my model to get a good orthophoto, with the full 38 Mio points it seems to take 120 Hours? Is there a general rule about the number of faces I need dependend on the complexity of terrain and size of the area?

thank you very much,

Ludwig
