Hi Sushi,

I think the off-axis slice/projection plot will meet your requirement best, where the camera orientation is determined by the normal vector:

http://yt-project.org/doc/visualizing/plots.html#off-axis-slices
http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots

And of course, if you’re interested in the features provided by volume rendering, it’s also worth a try. This cookbook gives an example of moving a camera; specifically you might want to use the camera.rotation:

http://yt-project.org/doc/cookbook/complex_plots.html#moving-a-volume-rendering-camera

Dear yt:

I would like to change/customize/rotate my camera angle for my slice plots without rotating the axis.

What options do I have using yt if I want to move my camera angle by say 45 degrees?

Can I use the following link or can you suggest me something else

Thanks in advance
