I have an enormous Enzo file that I want to volume render. It takes way too long to render it at full resolution. I have extracted a covering grid and dumped the raw data to a file. Then I read that data into another rendering engine (Boo) and rendered it. What I want to do is volume render the covering grid. I generate the covering grid like this:
lowerleft = [0.,0.,0.]
datasetname = "/work/01197/semeraro/Cooldata"
ds = yt.load(datasetname)
cg = ds.covering_grid(max_level,lowerleft,ds.domain_dimensions*2**max_level)
Then I try to do something like this:
min,max = cg.quantities.extrema('Density')
and I get a stack trace ending in
File "/work/01197/semeraro/maverick/yt-x86_64/src/yt-hg/yt/data_objects/data_containers.py", line 578, in selector
yt.utilities.exceptions.YTDataSelectorNotImplemented: Data selector 'covering_grid' not implemented.
Obviously I cant do that. So what am I doing wrong here?
Oh and I am making a movie for SC15 and if I get this figured out it will run in the TACC booth.
