javascript - Dynamically Change Three.js texture in externally loaded Collada file -

-

i using three.js collada loader import .dae file texture (.png) image applied. need overwrite .png file new texture, , creating texture using canvas element exports .png format. if clear cache, change texture (i naming exported "new" .png texture same filename original .png texture referenced in .dae file).

how can ensure new texture recognized/rendered without having user clear cache? example: user creates new texture, , exported on original texture, , collada file re-renders after user clicks button render box.

once have javascript image object in memory, regardless of source, can assign objects' materials' textures via .image attribute. you'll need let thre.js know alter binding. example, if have new image called, say, img , mesh called mesh typical material:

mesh.material.map.image = img; mesh.material.map.needsupdate = true;

should trick. no need send dom elemetn disk .png, use it.

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
