Data files interpolation

Hello!

I know that radiance do interpolate data files linearly.

Is it possible to let it interpolete them in other ways?

Same about light distribution data files.. beeing in the end data files, I assume they are linerly interpolated as well, are they? Is it possible to change their interpolation as well ?

Hi Lucio,

You have the source code, so you are free to do what you like with it. The linear interpolation routines are in src/rt/data.c. You should be careful that whatever interpolant you use does not go outside the limits of the input data. Bicubic interpolation is notorious for producing negative values on all-positive input data, something that can be problematic in a lighting simulation....

Cheers,
-Greg
