Curt, I feel strongly that continuous LOD is the 'solution' to dynamic large-scale high-detail scene generation. It is efficient in time and memory, simple to...

Tom, Seams are only an issue if you end the texture at the edge of the polygon. The textures have a small border which is off the edge of the polygon, so when...
