   * Management of 3D masking by far away objects : Does not manage masking by objects farther than ~5 meters. (but to be tested further).
-  * Still tracking in low light ? Good enough for displaying UAPs at rather far distance (>20m)
+  * Still tracking in low light ?
     * Tested in office : can track in rather low light. But not in the complete dark.
     * some city lights around are enough for getting a stable tracking in orientation. The HL2 struggles with the stable placement of nearby holograms. North direction remains stable.

   * Very bad color rendition. Even worse on the sides of the field of view
+  * Good enough for displaying UAPs at rather far distance (>20m)
