[yt-users] Mirroring Cartesian data about a plane for volume rendering

[Suoqing Ji]

Hi Dan,

I don’t think there’s a direct option of mirroring in volume rendering, however this is definitely doable via other ways.

One way I can come up with is, you could specify the region above/below z=0 plane and extract fix resolution data from it (see http://yt-project.org/docs/dev/cookbook/constructing_data_objects.html#extracting-fixed-resolution-data <http://yt-project.org/docs/dev/cookbook/constructing_data_objects.html#extracting-fixed-resolution-data>), then mirror the data and pass it to volume rendering.

Best wishes,

My guess is that I'd have to perhaps make a new array representing the data and do the mirroring by appropriately copying the elements. However, I'm unsure how to go about this--especially for AMR data. Does anyone know of any built-in functionality that might be useful for this?
