[yt-users] camera and boolean object

I have a question about volume rendering. I'd like to run camera.allsky_projection on a data object with a particular shape, in this case a sphere with a cylindrical hole in the center. I was able to define such an object using the boolean operator "NOT". But feeding it to camera.allsky_projection leads to an error, with the traceback below.
Traceback (most recent call last):
File "sky_maps.py", line 70, in <module>
inner_radius = rr, rotation = rotation)
File "/Users/mkjoung/work/yt/yt-i386/src/yt-hg/yt/visualization/volume_rendering/camera.py", line 1526, in allsky_projection
dx = min(g.dds.min() for g in pf.h.find_point(center))
AttributeError: 'AMRBooleanRegion' object has no attribute 'h'
(allsky_projection runs successfully when I input 'pf' as an argument.) Is there a workaround so that allsky_projection will accept the boolean object as pf-like?
