How could I get this 3d grid to translate to this 3d space. what is want is for me to be able to move this box around this room, and anywhere I move it, the dimensions will be correct relative to the room (vanishing point should be that black dot). I've just began messing around with 3d so I don't fully understand all of the variables yet, but I've been messing around looking for results.
use WASD to move the box around and check results I'm using this project to make a show where pen lasers are projected into this 3d space
