fractals
Back in 1995, I put together a fractal landscape generator. It included support
for a snow-line, the boundaries of which were determined both by altitude and
steepness of the mountain section. The shader was a simple polygon engine with
phong coefficients, z-buffer and back-face removal.
Your basic fractal mountain.
Low resolution mountain, to show how snow is applied.
High resolution mountain with snow.
Very high resolution mountain. About a million polygons
used to create this image.
