I got texturing to work

For the moment, I scale the base UV of each quad by a merge count in the two posible axes. Setting GL_REPEAT to both texture wraps, this gives the illusion that all the voxels are textured individually. I expect to run into some problems with this solution and texture atlas (They are pretty much incompatible). Maybe instead of texture atlas I can batch all quads with the same texture.

Here are some nifty pics:

Wow, excellent work again... I'm actually suprised your getting such good results and performance using the fixed function pipeline and immediate mode. But well done.

You might find 'SurfaceMesh<VertexType>::extractSubset' to be useful, though I don't know if it works with the cubic mesh. It might be easier to write your own version which works directly with your quads.

I'm using display lists, not immediate mode. Performance wise, they are at the same level that VBOs (Sometimes even faster!). Only two drawbacks that I'm aware of: First, they can't be modified. Second, to create display lists in another thread you have to do some funky rendering context switches, as OpenGL has zero (0) threadsafeness.

I got threading to load/generate/save chunks on demand, but I build the display lists in the main thread because I kind of like my current head and wouldn't like it to explode.
