POPSImpressive Real-Time Terrain Render
Here's a really impressive-looking terrain rendered with a custom engine by Simon Jacoby. It gives a good perspective on what a difference the right tool (World Machine) along with normal mapping and proper lighting can make. Here's an explanation by Jacoby: Here's how I do it: "1. Load the heightmap (512x512, greyscale, generated in WorldMachine) 2. Create a normalmap with corresponding per-pixel AO with D3DXComputeNormalMap() 3. Downsample the 512x512 heightmap to a 64x64 map 4. Generate the terrain mesh with the 64x64 texture 5. Compute the tangent-space transforms with NVidias MeshMender 6. Raycast a shadowmap to a shadowtexture, on the CPU Rendering is then regular normalmapping, and the result of each pass (ambient + two directional lights, of which the key light is modulated by the shadow map) is modulated by the AO factor stored in the alpha channel of the normal map texture. As I said earlier there's also a few more passes for color and fog, and there's noise mix
