Quaternion

Overview

Quaternion is a class in Aspose.3d for Typescript. Inherits from: Quaternion.

Quaternion.constructor creates a quaternion with default components (0,0,0,0).

Properties

Name	Type	Access	Description
`w`	`number`	Read	Is the scalar component of the quaternion
`x`	`number`	Read	Is the first vector component of the quaternion
`y`	`number`	Read	Is the second vector component of the quaternion
`z`	`number`	Read	Is the third vector component of the quaternion
`length`	`number`	Read	Returns the magnitude of the quaternion

Methods

Signature	Description
`constructor()`	Initializes a quaternion with the given w, x, y, and z components
`constructor(w: number, x: number, y: number, z: number)`
`constructor(w: number, x: number, y: number, z: number)`
`IDENTITY()` → `Quaternion`	Returns a quaternion representing no rotation (identity quaternion)
`normalize()` → `Quaternion`	Returns a unit-length quaternion equivalent to the original
`conjugate()` → `Quaternion`	Returns the conjugate of the quaternion, negating the vector part
`inverse()` → `Quaternion`	Returns the multiplicative inverse of the quaternion
`dot(q: Quaternion)` → `number`	Computes the dot product between this quaternion and another
`concat(rhs: Quaternion)` → `Quaternion`	Multiplies this quaternion by another (rhs) and returns the result
`eulerAngles()` → `Vector3`	Converts the quaternion to Euler angles and returns them as a Vector3
`fromEulerAngle(pitch: number, yaw: number, roll: number)` → `Quaternion`	Overload creates a quaternion from either a Vector3 or separate pitch, yaw, roll numbers
`fromEulerAngle(vec: Vector3)` → `Quaternion`
`fromEulerAngle(pitch: Vector3 \| number, yaw: number, roll: number)` → `Quaternion`
`fromAngleAxis(a: number, axis: Vector3)` → `Quaternion`	Builds a quaternion representing rotation of angle a around the given axis
`fromRotation(orig: Vector3, dest: Vector3)` → `Quaternion`	Creates a quaternion that rotates vector orig to align with dest
`interpolate(t: number, fromQ: Quaternion, toQ: Quaternion)` → `Quaternion`	Linearly interpolates between fromQ and toQ by factor t
`slerp(t: number, v1: Quaternion, v2: Quaternion)` → `Quaternion`	Performs spherical linear interpolation between v1 and v2 by factor t
`toString()` → `string`	Returns a string representation of the quaternion components
`equals(other: Quaternion)` → `boolean`	Checks whether another quaternion has the same component values
`toMatrix()` → `Matrix4`	Converts the quaternion into a 4x4 rotation matrix
