I've built a rudimentary terrain builder, and I'm texturing it with a
scanned-in image of a map. The image file (rgb) is in one piece, but I've
implemented a terrain sectioning algorithm that breaks down the geometry
recursively and spatially, eg. 1 section into 4, then each of the 4 breaks
down, etc. I can map the texture vertices correctly on the sub-sections,
but the texture file is getting read for each piece, and fills up texture
memory with a lot of redundant imagery!
I've already tried making one big terrain, then using pfuBreakup on it, but
I need to have different LOD's.
Question is, how do I read only one copy of the texture, then split it up
somehow to cover the individual sub-sections? Only was I can figure so far
is to perform my own "Breakup" of the terrain.
Any help or ideas appreciated!
