Hello, I have implemented a terrain generation application in OpenGL for my university dissertation project. The terrain is generated using functions such as those containing sine or cosine. For example, z = sin x + cosy would give an egg box type shape. By using more complex functions and combining height maps made from different fuctions, all kinds of terrain can be simulated. To see how effective it can be check out my web site: Terrain Generation My Homepage Edited by - RandomHippo on 5/9/00 5:13:00 PM Edited by - RandomHippo on 5/9/00 5:18:26 PM Edited by - RandomHippo on 5/9/00 5:19:31 PM
