Three-Dimensional Rotation Matrix

Description

Render a 3-Dimensional projection matrix given positive or negative degree changes in yaw, pitch, and / or roll.

Usage

rotate3D(yaw, pitch, roll)

Arguments

yaw

z-axis change in degrees; look left (+) or right (-). Consider this a rotation on the x-y plane.

pitch

y-axis change in degrees; look up (-) or down (+). Consider this a rotation on the x-z plane.

roll

x-axis change in degrees; this change appears as if you touch head to shoulders: right roll (+) and left roll (-).

Details

When plotting with the package scatterplot3d, the default perspective is such that the pitch action appears as a roll while the roll action appears as a pitch.

This function is used only in data generation of the package vignette. This function is called by rotateScale3D().

Value

A 3 x 3 projection matrix corresponding to the degree changes entered.
