Direction, Tilt and Roll Angles
TerraExplorer Pro provides six degrees of freedom in the 3D World by enabling you to control the location of the camera (x, y and altitude) and the viewing angles (direction, tilt and roll).
Direction, Tilt and Roll Angles
Direction values:
Range from 0 to 360 where 0=North, 90=East, 180=South and 270=West. TerraExplorer Pro adjusts illegal values to this range by modulating the illegal number.
Direction Angle
Tilt values:
Range from -90 to +90 where 0 = Horizon, +90 = straight up and -90 = straight down. TerraExplorer Pro adjusts illegal values to this range by modulating the illegal number.
Tilt Angles
Roll values:
Range from -180 to +180 where 0 means the plane is aligned with the horizon, +180 = Full roll right and -180 = Full roll left.
In both cases, when the roll is 180 and -180, the plane is flipped on its back. TerraExplorer Pro adjusts illegal values to this range by modulating the illegal number.
