I am trying to do a simple landscape renderer using a mesh (like this)

| \ | / |

| / | \ |

repeated many times to create a neatly curving landscape. At the moment I am using triangle fans to draw them, but I have been told there is a more efficient triangle strip. I can’t find it (does anyone know what it is).

For a simple landscape renderer the trifans seem to be efficient…

But, how does the mesh look when width and height are greater?

triangle strips will “crack” when you start adding height. try it alternate a sin function and a cosin for each other strip. You need to define your own algorithms to create a real mesh (well I couln’t find any). email me at and I’ll send you what I developed. Probably not great but works regardless of height displacement.
