Euler

class Euler extends MathArray extends Array

A class to handle Euler rotation. More information on rotation using a Euler vector can be found here. Generally speaking the three components of the Euler object represents the roll, pitch and yaw angles and the rotation is applied according to a specific rotation order.

Usage​

import {Euler} from '@math.gl/core';

Constants​

  • Euler.ZYX

  • Euler.YXZ

  • Euler.XZY

  • Euler.ZXY

  • Euler.YZX

  • Euler.XYZ

  • Euler.RollPitchYaw

  • Euler.DefaultOrder (= Euler.ZYX)

  • Euler.RotationOrders = ['ZYX', 'YXZ', 'XZY', 'ZXY', 'YZX', 'XYZ'];

Members​

x, y z​

x, y, z angle notation (note: only corresponds to axis in XYZ orientation)

roll, pitch, yaw​

roll, pitch, yaw angle notation

alpha, beta, gamma​

alpha, beta, gamma angle notation

phi, theta, psi​

phi, theta, psi angle notation

order​

rotation order in all notations

Methods​

constructor​

(x = 0, y = 0, z = 0, order = Euler.DefaultOrder)

  • Number|Number[], Number, Number, Number

fromRollPitchYaw​

Common ZYX rotation order

euler.fromRollPitchYaw(roll, pitch, yaw)

fromRotationMatrix​

euler.fromRotationMatrix(m, order = Euler.DefaultOrder)

fromQuaternion​

euler.fromQuaternion(q, order)

copy​

If copied array does contain fourth element, preserves currently set order.

euler.copy(array)

set​

Sets the three angles, and optionally sets the rotation order. If order is not specified, preserves currently set order.

euler.set(x = 0, y = 0, z = 0, order)

toArray​

Does not copy the orientation element

euler.toArray(array = [], offset = 0)

toArray4​

Copies the orientation element

euler.toArray4(array = [], offset = 0)

toVector3​

euler.toVector3(optionalResult)

fromVector3​

euler.fromVector3(v, order)

fromArray​

euler.fromArray(array, offset = 0)

getRotationMatrix​

euler.getRotationMatrix(m = new Matrix4())

Returns Matrix4 - a rotation matrix corresponding to rotations per the specified euler angles

getQuaternion​

euler.getQuaternion()
