quat: Create a quaternion

In MrMallIronmaker/dddr: Three-Dimensional Spatial Operations in R

Create a quaternion

Description

Creates a quaternion, a four-dimensional number that represents 3D rotation well. The values underneath the quaternions are not interpretable for the naive user; however, one can learn how to read these values. See the vignette [TODO: link vignette] for an explanation.

Usage

quat(w, x, y, z)

axis_angle(axis, angle)

Arguments

w, x, y, z	Numeric vectors of the quaternion values. It is rare to need to access these fields.
axis, angle	Define a quaternion using axis-angle convention
