= Flyby Version 0.8
= Written by Joshua Anderson

This is the latest (read first) release of Flyby! A little demo I wrote that shows off my terrain engine with one of the best views of a terrain one can get; a flyby.

Hopefully the lines below will answer some people's questions before they ask (but don't hesitate to ask any questions you do have)

The terrain was pre-generated by a program that I wrote (based on Musgrave's algorithm)

The shading and shadows were generated by a simple raytracer (one specifically designed for height fields, it is quite simple).

The placement of "grass" and "snow" were also generated from the terrain dataset. (although the algorithm allows for more than two types of terrain).

The actual grass texture was tiled into the texture by Paint Shop Pro (I'm hoping I can make this automatic too (if I find the time))

The terrain rendering system is a based on the paper on quadtree terrain rendering by Rottger, Heidrich, et all.
Oh, and credit for the model goes to some unamed person who submitted it to the free section at

What the next version may or may not hold:
  • If you pay attention, you will notice terrain "popping". Writing geomorphing code is the next thing on my list.
  • It really needs a sky
  • BIGGER areas (memory is the current limitation, I'm working on a caching system)
  • more/better textures
  • memory consumption (I'm currently using 3 or 4 bytes a vertex that I don't need to be).
  • maybe a cockpit view? hmmmmmmmm....... I'll have to write it and see what it looks like to fly between mountain peaks that fast
