I am trying make terrain LOD using glDrawElements and VBO.
I am rendering 4096x4096 terrain using 64x64 blocks (64x64 polys).
LOD1 has 24576 indices
LOD2 has 6906 indices
LOD3 has 2298 indices
LOD4 has 3444 and that’s my problem.
I need to design terrain lod. This image shows LOD3 and LOD4
I am using only triangles. perhaps, u can use triangle fans on borders, but i don’t know, how make them in one buffer, in one element.
do you know about good site ? Do anybody have experience with terrains ? Thank you
