Description of the problem: Topic title says it all. Is there an engine for drawing Gabor gratings on the fly in PsychoJS?

Hi @pgerhard, see PsychoJS is not creating my Gratings. Looks like they’re not yet implemented.

Thanks I’ll figure out how to use images in my staircase

depending what you are using your staircase for here is a demo that uses orientation https://gitlab.pavlovia.org/lpxrh6/staircase-demo

It just uses picture stimuli. Without luminance calibration the grating stim won’t be a true Gabor.

Thanks! I am seeking to do a contrast test - I will try to do this using Matlab & PTB or the code you have posted to generate full images
