Projector
The Projector corresponds to the mirrors and the PGU. Mirrors are numbered following the light propagation (so they are numbered from the Picture Generation Unit (PGU) to the Eyebox).

Projector Parameters
Mirror Type
Freeform mirror type created for the optimization.
Fold mirror type used to reduce the volume of the projector.
Distance
The distance applied to a mirror or PGU corresponds to the distance separating it from the previous elements.
Horizontal Angle / Vertical Angle
the horizontal and vertical angles corresponding to the orientation of the element in the global axis system.

Multimirror Freeform Case
You can create HUD systems with two freeform mirrors. Using multifreeform definition allows you to gain space and obtain a higher quality of results.
The combination of the freeform mirrors helps fold the system and improve the quality of the virtual image by progressively deviating the light.
