<br>
It looks to me like the adaptive healpix volume renderer has bitrot.<br>
My guess is that this dates back to the threading changeover. I am<br>
the original author of this functionality.<br>
<br>
If someone else is able to look at it and update it, it would be<br>
greatly appreciated. Unfortunately, I cannot take on this<br>
responsibility at this time. Please fill out a bug so that it does<br>
not get lost.<br>
