Public ReadOnly Property ForwardDirection As Vector3

Property Value

Vector3 Vector3

float3

The forward direction unit vector.

Remarks

[!NOTE] On most Windows Mixed Reality devices, the forward direction vector is parallel to the ground when the user's head is in a neutral position looking forward. However, earlier versions of HoloLens 2 aligned the vector to be perpendicular to the display panels instead, which is tilted downward a few degrees relative to the ideal orientation. Newer versions of HoloLens 2 have corrected this to ensure semantic consistency across form factors.
