[Radiance-general] Interpolate BSDFs

[CHI-German Molina]

Hi Lars, Thanks a lot for the quick answer, but I think my question was not
really clear.

What I want to achieve is to get the directional transmitance from" any"
angle. Interpolating  would allow me getting a continuous (although not
really exact) value. This is mainly for visualization purposes, not really
for getting exact values. By increasing the number of patches I would have
a better resolution, but still I would have "bins" and not a continuous
value.

I hope is clear. If it is too hard (i.e. there is not any program that does
it for me), I can just increase the number of bins, and just smooth the
final image.

Thanks a lot!

Germán
