Hi,

I did some simple volume rendering with the following script:

volume2 = AMRKDTree(pf, fields=["Dark_Matter_Density"],

no_ghost=False, tree_type="domain",

le=c-0.5*WW, re=c+0.5*WW)

cam = pf.h.camera(c, L, W, N, tf, volume=volume2, no_ghost=False,

north_vector=L, steady_north=True)

cam.snapshot(fn="%s_iso-DMdensity-%3.3d.png" % (filenameTHIS, j))

I got rather strange results in that the pictures look symmetric, which I am pretty

sure can not be true.

I attach the obtained plot.

Note that I am using KD tree and using 32 cores.

Your help at your earliest convenience is appreciated.

Best,

Renyue
