Module: rotation
Provides platform rotation and orientation in quaternions on Android and iOS devices.
Functions in this module:
| Functions | Short Description |
|---|---|
| (rotation-x) | Returns x*sin(θ/2) |
| (rotation-y) | Returns y*sin(θ/2) |
| (rotation-z) | Returns z*sin(θ/2) |
| (rotation-w) | Returns cos(θ/2) |
| (rotation-accuracy) | Returns estimated heading accuracy (in radians, only Android) (-1 if unavailable) |
| (rotation-vect) | Returns rotation /quarternions list (list (rotation-x) (rotation-y) (rotation-z) (rotation-w)) |
| (rotation-roll . v) | Returns roll angle in radians (derived from sensors or rotation vect) |
| (rotation-yaw . v) | Returns yaw angle in radians (derived from sensors or rotation vect) |
| (rotation-pitch . v) | Returns pitch angle in radians (derived from sensors or rotation vect) |
| (rotation-orientation . v) | Returns orientation angles as list in degrees (derived from sensors or rotation vect) |
| Support Functions | Short Description |
|---|---|
| (rotation:rad2deg) | Converts single value or list from rad to deg |
| (rotation:deg2rad) | Converts single value or list from deg to rad |
