objective c - ARKit : how to find all planes hit by a hitTest? -

-

i have array of planes (non infinite planes => finite dimensions) in array:

plane *plane = [[plane alloc] initwithanchor: (arplaneanchor *)anchor]; [self.planes setobject:plane forkey:anchor.identifier];

(plane object heritates scnnode , has arplaneanchor *anchor , scnplane *planegeometry properties)

how find planes of array planes hit hittest @ point of screen ?

thanks !

i use categorybitmask , set example 3 (=11b). set categorybitmask option in hit test 2 (=10b). way nodes second bit of categroy 1 returned.

batch file - filebot superstrict script: need tiny video sample or other solution -

-
seeing how filebot can make massive mistakes (even in strict mode) when renaming videos created script make sure there's no mistakes , lets me check suspicious ones manually. it uses dummy 0-size copy of video in dedicated folder figure out new name renamed , doesn't tagged video , audio info since it's not real video. it simpler , more accurate have variable tags in place need tiny part of video (with tracks) instead of 0-size dummy. what's easy way this? all unknown variables see extrapolated video filename in other script, should not relevant here ask away if need be. @echo off /f "tokens=*" %%f in ("%full%") ( set "fullpath=%%~dpf" set "file=%%~nxf" ) :: prep fake temp file set tempdir=%temp%\%date:~3,2%%date:~6,2%%date:~11,2%%time:~1,1%%time:~3,2%%time:~6,2% mkdir "%tempdir%" && copy /y nul "%tempdir%\%file%" >nul :: filebot string (to shorten lines) if "%type%"...
