smoother terrain

Raloth · 2003-10-10T06:29:06

I was thinking of something like a bunch of bezier curves, with the center of each tile being a control point. This would let you get a very smooth terrain instead of being restricted to triangles. It also gives a perfect setup for level of detail. Just use a lower tesselation count for objects farther away. Is this practical? It seems like it would be a lot of work for the cpu, but then again there is no need to worry about a more complex level of detail system. The GPU would also be rendering more than it would with a standard triangle mesh, and texture coordinates could be a pain. Opinions?

i would use bicubic interpolation. its very smooth, passes through all your heightmap nodes, doesnt require additional controlpoints, and not too cpu expensive.
