HexWorld

Hex-based procedural terrain, including an algorithm to create procedural river systems and biomes.  GPU-based shaders used to show rivers, waterfalls, lakes and ocean.

To navigate the terrain:

Left/Right/Up/Down: move

Q/E: rotate

</>: zoom

(It takes significant mathematics to compute the hex-based terrain, so there will be a delay of a few seconds before the 3d world becomes visible).

See my blog for further details on the mathematics:
