Thanks Suoqing. I have actually seen those scripts. But I am still struggling to figure out how to do a movie like this,

What I want was to fly through the box, identify the largest halo and rotate it. I can zoom in, move the camera to the most dense region using the sample script in the cookbook, but the rotation was not satisfactory. it must be related to the north vector and the focus point I guess, but I haven't figured out how to tune it. So I am wondering whether anyone has done the same visualization using yt? Any advice helps.

Hi all,

I am trying to create a fly-through movie for my ENZO data (similar to those millennium simulation movies). Has anyone does this using yt? I understand that this probably can be done by tweaking the parameters for the camera, but am not sure how to do it exactly.

Many thanks in advance,
