I wonder if it would be useful to have instead of single threshold slider in the 3D viewer, to have low and high thresholds, so a range of greyscale values can be rendered as volume.

The effect of a double-sided threshold, as well as much more complex intensity adjustments, can be achieved by 'Edit'->'Adjust transfer functions'.

'Adjust threshold' so far uses accelerated Java 3D functionality, which is only available for a lower threshold. I thought it's better to not mix both functions, and instead leave the threshold as it is for accelerated adjustment, while providing the more flexible thresholding possibilities indirectly with the transfer functions.

Best,
Bene

Seeing as how you can already achieve this effect in the way Bene described -- as well as the fact that you could also do so by writing a macro to modify the pixel values via threshold + "clear outside" before sending it off to the 3D Viewer -- I think it is safe to close this bug as "won't fix."
