Quaternion

Extends:

three~THREE.Quaternion → Quaternion

Represents a Quaternion, a way to describe a spatial rotation that is less susceptible to gimbal lock.

This class extends the one from Three.js, API available here : https://threejs.org/docs/index.html#api/en/math/Quaternion

Method Summary

Public Methods
public	getDirections(): Object
public	setFromGyro(compass: *) Can be used in the transform of a perspective camera to produce a "blind camera" effect : move the screen around to frame a part of the current scene like if you were using a camera.

Private Methods
private	createGyroQuaternion(alpha: Number, beta: Number, gamma: Number, screenOrientation: Object) Creates a Quaternion that matches the device's current orientation. Calculated in radians.

Private Methods

private createGyroQuaternion(alpha: Number, beta: Number, gamma: Number, screenOrientation: Object) source

Creates a Quaternion that matches the device's current orientation. Calculated in radians.

Params:

Name	Type	Attribute	Description
alpha	Number		the angle to use for the quaternion creation
beta	Number		the angle to use for the quaternion creation
gamma	Number		the angle to use for the quaternion creation
screenOrientation	Object		orientation of the screen in degree! Can be very different depending on the plateform...
