IDL Folks,
I am interested in rendering a (sparse) 3D data set to create
a 3D volume, which I can then "slice and dice." My data set is
simply a (256,256,1400) floating point array. The first two
dimensions are x and y, and the third dimension is the z axis.
I tried using shade_volume and polyshade, and either through
my 'user' error of not knowing how these functions worked,
or through the fact that my data set is sparse, these functions
always produced nonsense or else returned an error. I
experienced similar frustration with the voxel_proj function.
Does anyone have a simple example showing how to render a
3D volume, or at least can give some pointers? I followed
the example in the Volume Visualization chapter of the
IDL Basics book just fine, but I couldn't do the same for my
data set :(.
My (temporary) solution was to use the IDL Slicer and make the
cuts through the z plane be fairly transparent. The results
look pretty nice, but it is still not a 3D volume.
See:

to get an idea of what my data set is like and my temporary
solution.
Thanks in advance,
Amara
