Fast Computation of Terrain Shadow Maps
A tutorial on the lighting and shadowing aspects of terrain rendering. It presents a simple and elegant solution for terrain self shadowing.
Terrain Generation Tutorial
Playing around with the circles algorithm, presented in Lighthouse3D terrain tutorial, Bob Nystrom has come up with very interesting variations including valleys and islands. All packed in a cleanly presented tutorial.
An algorithm to create a realistic looking planet is presented by Paul Bourke in this tutorial, together with source code.
Continuous LOD Terrain Meshing Using Adaptive Quadtrees
Reviews the problem of terrain rendering namely the memory problem of storing a height field. An algorithm using an adaptive quadtree is then presented. Thatcher Ulrich. Gamasutra.
Generating Random Fractal Terrain
An easy to follow tutorial presenting some of the basic techniques of terrain generation using fractal algorithms. Source code is provided. Paul Martz.
An easy to follow tutorial on both terrain generation and texturing. It shows you how to combine two textures using the terrain slope to get an adequate terrain texturing. Pseudo-code is provided.
