Grass Experiment

Geplaatst door Reinder Nijhoff op 20 July 2006

This demo uses verlet integration to simulate the physics of grass.
The grass reacts to wind and the movement of the camera. Walk backwards, and watch the bending grass.
Impostors are used to render trees and grass in realtime.

Geplaatst door Reinder Nijhoff op 25 August 2005

After spending most of my free time last year writing a raytracer, I've finally finished another OpenGL demo.

This demo loads a Doom-3 level (using the .proc format) and renders the level using portal-based visibility culling. I use the OpenGL Shading Language (GLSL) to render the levels using the light-data loaded from the .map files.

Geplaatst door Reinder Nijhoff op 25 August 2004

I think that I've figured out how the .cm files in Doom III are used for collision detection.
In the .cm files the nodes discribing a tree are saved in the following format:
( 0 320 )
( 1 -1351.9996337891 )
