Hi, I have searched all over the Internet and backwards through the postings in these forums but I can''t find something that helps me actually implement a terrain engine in DirectX. I have trouble with the academic style "papers" and most of the other material is for OpenGL. I am currently waiting for this book Real Time 3D Terrain Engines Using C++ and DirectX by Gregg Snook but it doesn''t come out until July. What''s the best resources you have used? I have seen those articles on Gamasutra too

Isn't that an OpenGL implementation? I was under the impression it was. You're talking about the book by Trent Bollack right?

Yeah, Pollack's book is OpenGL. It's a good introduction to the basic concepts, though, and it's not hard to port the code as long as you understand how to render vertices in DirectX. I haven't been able to find an all-encompassing example that covers the various direct3d topics in-depth. I've had to port and pillage various opengl examples from all over to get my terrain working.

Mine is a Rottger quadtree terrain in DirectX. It includes a heightmap, quadtree, LOD based on distance and error, frustum culling, directinput(immediate for now), MD2 loading (with animation), very ugly camera work, and a skydome (no texture yet). It's very much a work in progress but you're welcome to take a gander at my code.

The plan is to go back and start from scratch implementing all the things I've learned in a much more well-organized engine. My journal of the evolution is here
