Hey gang. I've just started putting together some visual aids in understanding what happens in a scenery build process. That's well and good, but I'm having an issue with terrafit. I've recently discovered that my understanding of how terrafit works is wrong. I'd always assumed it took a grid of elevations, calculated "planes of best fit", using the max error threshold, then adjusted all the heights in the grid. It turns out that it actually leaves the heights unchanged, but deletes any that aren't deemed significant. I've been reading through terrafit.cc, but I can't figure out anything about what it does to determine significance.
Could anyone explain to me how terragear uses the error threshold to determine what the list of points to be included is? The very beginnings of my site for this have been slapped together (like, 20 minutes ago), so what's there is VERY MUCH still being written, expanded, and edited. But you can get an idea of what I'm trying to do at www.cullam.com/flightgear.htm. If you have Google Sketchup, you can actually see the 3D models I've built, as some of the pictures aren't very useful in two dimensions. My models of terrafit's process are obviously wrong, as I made them to model my understanding at the time. But if somebody can better explain it to me, I'll do more accurate models. With any luck, this guide will eventually be useful for people who want to get into the scenery game. -cullam __________________________________________________________________ Make your browsing faster, safer, and easier with the new Internet Explorer® 8.
