Hi, I’ve just unsuccessfully trawled the site for example code for rendering terrain and haven’t found anything.
Did I miss something?
Ultimately I’d like to do something with Orthogonal Illumination Maps…

If anyone has any idea on where I can find more detailed information about implementing this stuff with GL, then please point me in the right direction.
Thanks
Matthew
Well, I posted on my site a sequence of code to demonstrate how to make a simple terrain from a very simple to a more advanced manner.

I dont use lightmaps yet, but a good start is there…
Bye.

If you want to generate simple terrain you can load the Texture into the memory, and read the RGB of each pixel… THe color will represent the hight of your terrain … Then just create a grid of vertices and depending on the color their Hight will vary … Ten use GL_TRIANGLES to connect them and you have terrain …
However if you know how to read .raw files, its MUCH easier to generate terrain then with Bitmaps … You can just use Photoshop to save picture as .raw … Then just read each Character of from the file and save it in BYTE array[x][y] … Its very simple and give you Good terrain to start with .
