[Radiance-general] Removing black areas in imagemapping

[Per Haugaard]

Dear users,

I am mapping a falsecolor image on a working in a room but there is still some black parts left in the image.  I have FTINY as a guard against rounding errors but it does not remove everything.

As written i Axel J. tutorial I have build a .cal file with a nonzero function:

nonzero(r,g,b) = if(max(r,max(g,b))-FTINY, 1, 0);
fc_u = -(Py-16.6)/12.8;
fc_v = (Px-0.2)/12.8;

Any idea of how to remove the remaining black spots in the image?

The images can be seen at:

Happy new year
