Yes. In fact all that is done with the new_region() routine. (set step with the ijk_step argument, eg. ijk_step = (2,2,2). Set plane number by setting ijk_min, ijk_max to show one plane).

thx

is volume.py where I would find how to change step size, plane number & depth?

Here’s the Python declaration in chimera/share/VolumeViewer/volume.py where the Volume class is defined.

I am trying to modify the region bounds of the volume viewer using python. What module should I be looking at to determine the api calls?
