i used the ffmpeg command to extract sequential .png image files from the original depth perception (depth map) video, used the AppleScript to generate black & white wall-eyed stereogram .png image files automatically, and used the ffmpeg command to create an Apple ProRes 422 HQ video from seque...

random color image frames cannot be encoded in high quality due to the bandwidth limitation. and it doesn't look so nice visually either. i recommend using black and white patterns for stereogram animation. in JavaScript/AppleScript: // drop generate SIRDS AppleScript/JavaScript droplet for Sirds //...

this AppleScript script will repeat -180 to 180 degree phase sweep three times. set lp to -180 -- the lowest phase in degree set hp to 180 -- the highest phase in degree set rv to 0 -- set to 1 for reverse (hp to lp) set rp to 3 -- repeat 3 times if hp is less than lp then set tmp to lp set lp to hp...

Use "memmove()/bzero()" on both Intel and ARM since that's the only measurement available on ARM Mac at this point. EDIT: added temporal/non-temporal read/write tests for ARM Mac. you can now compare temporal/non-temporal read/write between Intel and ARM Macs. ../img/amm/20201210-memmove-b...

unfortunately, this is one of most frequently asked questions. starting from macOS Mojave 10.14, apps no longer have access to the microphone or other audio input devices unless you specifically "allow" each app to use the microphone or other audio input devices. when the app gets launched...
