Hi, Everybody-- I have a dumb question about getting fixed resolution buffers working in yt3.0. I'm trying the following:
slice = ds.slice(0,[0.5]*3) frb = slice.to_frb((1.0,'unitary'),[512,512])
frb['density'] yt : [INFO ] 2014-09-16 09:29:47,060 Making a fixed resolution buffer of (density) 512 by 512 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/visualization/fixed_resolution.py",
but accessing data in the frb is causing things to choke. Any idea what I might be doing wrong? Thanks! line 127, in __getitem__ int(self.antialias)) File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/geometry/cartesian_coordinates.py", line 54, in pixelize antialias, dimension, periodic) File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/geometry/cartesian_coordinates.py", line 67, in _ortho_pixelize buff = _MPL.Pixelize(data_source['px'], data_source['py'], File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/data_objects/data_containers.py", line 237, in __getitem__ self.ds.arr(self._generate_container_field(f)) File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/data_objects/selection_data_containers.py", line 231, in _generate_container_field self.index._identify_base_chunk(self) File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/geometry/grid_geometry_handler.py", line 280, in _identify_base_chunk gi = dobj.selector.select_grids(self.grid_left_edge, File "/home/dcollins4096/local-yt-2014-08-27/src/yt-hg/yt/data_objects/data_containers.py", line 546, in selector self._selector = sclass(self) File "selection_routines.pyx", line 974, in yt.geometry.selection_routines.SliceSelector.__init__ (yt/geometry/selection_routines.c:22578) TypeError: a float is required

I think you only need to specify 0.5, the coordinate at which you take the slice, not [0.5, 0.5, 0.5].
Thanks!

Thanks, Matt. I had somehow thought the slice took the center position. Thanks! d. d.
Thanks!
