glSOAR is ObjectPascal implementation of SOAR terrain rendering algorithm using OpenGL. It can be compiled using FPC or Delphi compiler and works in Windows and Linux (only benchmarking mode). No fancy OpenGL extensions are required, it should work with any OpenGL 1.2 and newer drivers.

SOAR algorithm was published by Peter Lindstrom and Valerio Pascucci in 2001. Papers and original C implementation can be found at SOAR starts with coarse terrain mesh each frame and uses view-dependent refinement (standard longest edge bisection) to calculate mesh to be rendered - stress is on the CPU.

    You need to be a registered user to download this file.

    But where can i register

  2. a nice work. but here is a link for original C implementation. on clicking it results in URL not found. Please send me the link for original C implementation.


    • Looks like directory structure of their server has changed, I fixed URL in the article to point to the new location.

  3. It looks that the link for original C implementation of SOAR is broken again… Could you please send me the link for the original C implementation?
