I’m using a circular aperture to produce a window through a larger circular gratingstim.
I’d like to apply the same raised cosine mask to the inner circumference of the gratingstim (aka the outer circumference of the aperture) as I have to the outer circumference of the gratingstim. I’ve attached a screenshot - the red radialstim denotes where I’m trying to put the rasied cosine mask. Is there an easy way to do this with the built-in stimuli generation functions - or would I be better off writing my own code to accomplish this? I’m using Psychopy 3.
