Opengl Question

[The-Guy]

How do you create a terrain in opengl ?

[parksie]

The same way you make any other object

Easiest way is to use a heightfield, say 10x10 nodes. Each of these nodes has a value from (say) 1 to 100, giving its height. Then, the hard part is generating a triangle strip across these values.......

Google should help you if you search for things like this.

Also, anything on www.gamedev.net might be useful.

Would a textured quad be good for a flat terrain ?

[Zaei]

Depends on where you plan to go with it. Lighting and Fog look REALLY BAD when applied to a very large quad, and you dont get very much flexibility. A better way would be to create several quads, and map a texture over all of them.

It's still best to decompose a single large object, since OpenGL only calculates lighting, etc., at the vertices, so the more vertices you have the closer you get to specular lighting (Phong shading, per-pixel shading, etc.) - there's a discussion on this at www.opengl.org.
