In my display there is a rotating grid of crosses (created and controlled with ElementArrayStim) and two static objects.
I would need the grid to be perceived in front of the objects (and yet without occluding them). Is there a way to a achieve this?
Thank you so much for any advice you can provide.
Do you wish to have the grid to appear nearer than the objects with stereoscopy or with some other depth cue conflict?
I would need a “trick” that does not require to wear special glasses
Chromostereopsis requires nothing other than careful stimulus colouring but can be remarkably effective.

Thank you Michael for this excellent idea. So clever! I’m working on it and it seems to work quite well.
Be aware that the direction of the effect isn’t universal - i.e. while most people perceive red objects to be in front of blue, apparently others perceive the opposite. Not sure how much of an issue that actually is, but you might need to check each individual and be prepared to switch the stimulus colours on a per-subject basis?
But would be interested to see if it works for you.
