Hi all, I’m new to MATLAB and Psychtoolbox. I am currently trying to create
concentric rings moving inward (with different contrast) for a task. I’ve seen a specific function with python that creates this (there seems to be none in MATLAB?). Saw a couple of papers that managed to create this using Psychtoolbox but still could not figure out how. Would very much appreciate any help I can get!
Have you looked at ExpandingRingsDemo.m?

Just did, thank you! Though it might not be what i’m looking for, it’s closer to what I want to make. Also found the “Radial Checkerboard Demo” and managed to create a static concentric ring in the middle. Might look into both of them further. Thanks again!
Expanding rings demos is the way to go. My Radial Checkerboard Demo is not really designed to be dynamic in the way you need.
Thank you! I’ll be sure to work based on the ExpandingRingsDemo.
I have some procedural (like ExpandingRingsDemo) grating shaders that do polar + radial + spiral square or sine gratings that can be animated:
Exactly the way I wanted it, thank you!
