[yt-users] Visualizing clumps in 3D?

[Matthew Turk]

Hi Eve,

You can volume render if you use the 'camera' interface, described here:

http://yt.enzotools.org/doc/visualizing/volume_rendering.html?highlight=camera#volume-rendering-camera

Supply the center to the camera to point it at a particular clump.
You can then add isocontours (using the "sample_colormap" function,
http://yt.enzotools.org/doc/reference/api/generated/yt.visualization.volume_rendering.transfer_functions.ColorTransferFunction.sample_colormap.html
) to a ColorTransferFunction to choose where you want the highlights
placed.  If you place them at the divergent densities, it should draw
out the features you're looking for.

Hope that helps,

Matt
