"Steppy" landscapes
Posted: Sun Dec 10, 2006 3:26 pm
I'm a member of a team working on a project, and somehow I've become the "senior heightmap tweaker"
Anyway, downloaded SE and played around with that, amazing results.
We eventually worked out the scale required, which basically meant a 33km x 24km map. That's also when I realised that I'll have to get pro, so while I'm waiting for my eval license details to come through, I thought I'd take a small section of the map, enlarge it to a more accurate scale, smoothed it a bit, and imported it.
On the original map, the Horz Scale was 16.1, since the image was at the max of 2048 (makes 32972.8 meters).
I decided then that the whole map should be done at a size of 8192, which allows a Horz Scale of 4.02, allowing finer detail to be worked out (although, it would be great to go even smaller on the Horz scale).
When I look in the viewer though, it's all a series of steps/ledges, no gradual change in height.
You can just about see this in the below picture.
Same landscape at Horz 16.1 for comparison.
How can I solve this and smooth the map better? Will this happen to me in Pro?
I'm assuming that because the max alt is 1000 (min 0), each pixel shade represents 3.9 meters.
Thanks, this is a great, easy to use tool!
