Name	Description
ENU = 0	ENU (East-North-Up) coordinate system. X - right, Y - front, Z - up, default in Unigine. Rotation order: Z -> X -> Y (Yaw-Roll-Pitch)
NED = 1	NED (North-East-Down) coordinate system. X - front, Y - right, Z - down, default in Unigine. Rotation order: Z -> Y -> X (Yaw-Pitch-Roll)
