MARTINI: Real-Time RTIN Terrain Mesh To render terrain in 3D, you need a triangular mesh — a set of 3D triangles representing the surface. The easiest way to get one from height data is a uniform grid (two triangles per pixel), but that's a lot of triangles. For fast rendering, we want to reduce this amount by adapting the mesh to the surface — using bigger triangles in relatively smooth areas, and smaller ones where there's a lot of detail. One such approach, proposed by W...
