Quote from: latego on November 18, 2007, 07:10:19 amI don't see the point for planet wide erosion. Erosion is a very local process so, as soon as you are considering areas larger than, let's say, 100km, what you see is the general structure of the terrain and not the erosion effects. Just have a look at pictures taken from astronauts in low earth orbit.As Cajomi wrote, modelling planet wide erosion would be a dreadfully complex task and then you would not be able to see the effects from long distances.The scale factor is fundamental in computer graphics: if you are modelling the whole Enterprise, can easily omit to create Kirk's coffee cup...Bye!!!
