<div dir="ltr">Thank you for fixing this! <div><br></div><div>I've been using it successfully on small data sets for the past day or two now and it's working smoothly. When I try to project on a large data set (1024 base grid) it's churning away for hours (8+) before I kill it. This seems like it's slower than it should be; is this true? If this is maybe a particularity of Ramses (or all octree data) I'd be happy to help out and work off-list with whoever the volume rendering guru is to streamline this functionality for these codes.</div>

<p dir="ltr">Okay, so my guess - although I am away from my
laptop/wifi at the moment - is that somehow the origin is being set
to the wrong location. I can think of a few possibilities,
like the width being twice what it should be or the default being
wrong. Can you try manually specifying the center a priori? One
thing that may be getting confused is the origin coordinates. For
off axis slices, the center always gets mapped to 0,0. I don't
think it works like that for off axis projections, though, where it
uses a different method of setting the center that is with respect
to the full domain.</p>

<p dir="ltr">How do the units compare to what's in your sim? Also,
what is your domain extent? My guess is there is an assumption in
the octree floating point coordinate generation that is missing a
domain_left_edge offset.</p>

<div>are off axis projections expected to work for all frontends in
