3D volumetric state/UI #16
Description
Currently, the image viewer has very little UI - no way of switching to volumetric rendering when available.
Will need appropriate adaptation of view control to use different camera etc - as well as looking into making sure other elements work etc.
Preferably should have a viv extension to make it possible to write depth values from the volume shader (with appropriate associated props/controls).
Need to establish a good example dataset to use for testing this.
