Quaternion QML Type

Factory functions for constructing quaternion values. More...

• List of all members, including inherited members

Methods

• quaternion fromEulerAngles(vector3d eulerAngles)
• quaternion fromQuaternion(QQuaternion q)
• quaternion fromRpy(vector3 rpy)

Detailed Description

A singleton helper (mirroring QtQuick3D's Quaternion type) that exposes the quaternion factory functions to QML. For example: Quaternion.fromEulerAngles(0, 90, 0).

Method Documentation

quaternion fromEulerAngles(vector3d eulerAngles)

Construct a quaternion from Euler angles in degrees.

Components of eulerAngles are (x = roll about X, y = pitch about Y, z = yaw about Z), ROS axis convention. An overload taking three real arguments (x, y, z) is also available.

quaternion fromQuaternion(QQuaternion q)

Construct a quaternion from a quaternion.

Takes the components of q in ROS order.

quaternion fromRpy(vector3 rpy)

Construct a quaternion from roll/pitch/yaw in radians.

Equivalent to fromEulerAngles, but rpy is in radians.
