Quaternions represent 3D rotation without gimbal lock. Multiplying each of the 8 local vertices by the rotation quaternion and adding world origin generates exact 3D corners.

Projecting the 8 corners with WorldToScreen and connecting 12 edges creates an authentic 3D box that tilts with slopes and stairs.
