15639	RFE: depth testing for volumes	Zach Pearson	Zach Pearson	"Currently it looks like opaque models are always drawn over volumes, even though opaque models are drawn first. The effect is pretty subtle and hard to notice when working with mostly transparent volumes, but becomes much more pronounced when we use a transfer function that makes the volume look opaque too. It would be good if fragments of the volume that are in front of fragments of the opaque model occluded the opaque model.

I'm not suggesting slow transparency effects for multi volume rendering, just enabling depth testing for volumes so that segmentations in volumes look correct. "	enhancement	assigned	moderate		Graphics				Tom Goddard Greg Couch				all	ChimeraX
