To build and run:

make
./PRT_demo


Example scene (500k verts) and visibility coefficients are located in dragon_floats.
This version uses buffer textures to store the precomputed visibility SH.
If this is not supported by your graphics card, or if fewer SH orders are necessary, 
a possible alternative is to store them in vertex attributes. See our mobile phone
demo or contact the authors.
