3D Mountains

"Lorenz hat"

"Lorenz hat" equation is
    y(x,z) ~ 1/(x2 + z2 + 1)
See Hidden Surface Removal Algorithms for a couple of hints.

Controls:
Drag mouse to rotate mountain.
Drag mouse with "Shift" to zoom it.
Press mouse with "Alt"("Ctrl") to increase (decrease) two times number of points.

Controls:
Drag mouse to rotate mountain.
Drag mouse with "Shift" to zoom it.
Press mouse with "Ctrl" to get new terrain!
Press mouse with "Alt"(+"Shift") to increase (decrease) two times number of points (you can see n value in the Status bar).
