Oh, we don’t have any ready tools for that, I’m afraid. Andy McNeil hacked it for the related paper. You can use Shirley-Chiu instead at whatever resolution you like. (Tensor tree with -t -1 turns culling off.) The number of patches per hemisphere is 2 to the power of the -g value times 2. For example, -g 4 would be 2^(4*2) or 256 patches per hemisphere. Isotropic tensor trees (-t3 rather than -t4) means you only have one hemisphere times 2^(g-1) incident angles.
I should add that WINDOW doesn’t support any non-standard Klems subdivisions as far as I know.
