TemporalGrating.m
Description
This script displays a circular sinusoidal monochrome grating and varies its contrast sinusoidally with respect to time between -100% and +100%. It is the same as LuminanceGrating.m except that in that demo the contrast is varied manually by the user via the keyboard.
Features Illustrated by this Demo
- The drawing of gratings.
- The use of the T-Lock system to vary the Bits++'s CLUT and thereby change the contrast of a stimulus.
- The way in which palette animation techniques can be used to quickly change the appearance of the whole screen.
- The ability of the Bits++ to display very low contrast gratings due to its enhanced dynamic range.
