orient user to north and other directions

[kfarr]

As a user I'd like to know which direction is north in my scene, and it would be nice to have a hint about which axis is which. (x+ positive is north)

Proposed solution:

• something similar to viewhelper from three.js editor

example:

simpler idea:

• instead of empty (blank) scene, place a stylized compass indicated north and x direction, perhaps incorporating grid or other styles such as semi transparent glass (a la vision pro) or subtle gray radial gradient similar to baked lighting
• ground plane could be a set of preset options in environment such as grid, compass
