gratings

Functions

sinewave([visual_size, ppd, shape, frequency, n_bars, ...])	Linear (horizontal, vertical, oblique) sine-wave grating, with some phase(s) as target(s)
squarewave([visual_size, ppd, shape, frequency, ...])	Linear (horizontal, vertical, oblique) square-wave grating (set of bars), with some bar(s) as target(s)
on_uniform([visual_size, ppd, shape, grating_size, ...])	Spatial square-wave grating (set of bars), on a uniform background
on_grating_masked(small_grating_params, ...[, ...])	Small grating, with a parallelogram-like shape, on a larger grating
on_grating(small_grating_params, large_grating_params)	Small grating on a larger grating
phase_shifted([visual_size, ppd, shape, frequency, ...])
grating_induction([visual_size, ppd, shape, ...])	Grating induction illusion using a sinewave grating
grating_induction_blur([visual_size, ppd, shape, ...])	Grating induction illusion using a blurred square-wave grating
