Use the coordinate system the data was given to you in.Top
If you need to enlarge or shrink the data, scale the viewer not the data in order to keep the data of constant value.
"Scaling the viewer" can be done easily by scaling the viewing location and movements before setting or changing parameters on a standard or head-tracked camera. (See Java 3D's "Platform" concept which is also used in GLUE via the "ROOM_TO_WORLD" transform.)Top
The $G stuff is that same idea as what you used for cs237 and with the particlevis stuff. Docs are in $G/shared/man. So, you should be pretty cool with that. The data idea is that there will always be a link to visualization data at $G/data/. Within that directory, we're still trying to figure the organization out. One thing is for sure, whatever the organization is, it needs to be clear and documented and we need to stick to it. Leor is in the process of putting some MRI data into that directory and this might help determine the structure, you 2 should meet and talk more about it for sure..
I suggest something like this:
this is where the this is the format of the data data came from nektar, would mean .rea, .rst files | pathlines is after it has been converted | to pathlines, pathlines-with-data is asf's | new format that dbk is using, and you | might want to use too, etc.. | | V V
$G/data/nektar/bat/dataset-name/pathlines $G/data/nektar/bat/dataset-name/pathlines-with-data $G/data/nektar/bat/dataset-name/etc..
For the MRI stuff, it would be:
$G/data/dti/susumo1/hair-volume-256x256 $G/data/dti/susumo1/hair-nvidia-compressed-volume-256x256 $G/data/dti/susumo1/etc..
Much of the data is a processed version of the original. In each directory where this is the case (pathlines derived from .rea .rst files for example) there should be a Makefile that will remake the dataset if anything should ever happen to it or we get a new one and want to use it as an example. So when you get jason's programs working to generate pathlines, put a command in a makefile to call it automatically with the correct settings for regenerating the dataset.Top
raw -- what came from an outside source orig - what it was converted to in our local data formats
