Hi there,
Once again I must ask for your wisdom and guidance :)
Is there anyway to make NaN values transparent. More specifically I'm using the slice function, and then texture mapping with some images. These images have some NaN values, wich i would like do be transparent. Is that possible?
Thanks in advance!

You can set the AlphaData and AlphaDataMapping associated with the surface plot created by slice()

In particular you could set it to
double(~isnan(TheImage))
which would be 0 exactly where there are nan.
