I started working on a terrain engine around October 2000. I was deeply moved by screenshots from black and white :)

My intention and main goal was to create something visually stunning. This meant writing a terrain texture-generator, and working hard to find good textures and blending modes.

The outcome is an engine that hold a (supposedly) 1km by 1km piece of terrain with very high accuracy. There is no triangle-cutting algorithm employed, simple brute-force. I use a large terrain texture and a tiling detail texture. There’s a skybox and the terrain reflects on the water.

I used OpenGL for this one, employing the OGLC skeleton to avoid most of the opengl-win32 business.

You can move through this world using descent keys (a,z, keypad). use ‘w’ to switch to wire-frame and ‘d’ to render without the detail texture.

A few screenshots:
