(To be removed) Convert viewpoint direction to orientation

vrdir2ori will be removed in a future release. For more information, see Version History.




vrdir2ori(d) converts the viewpoint direction, specified by a vector of three elements, to an appropriate orientation (virtual world rotation vector).

vrdir2ori(d,options) converts the viewpoint direction with the default algorithm parameters replaced by values defined in options.

The options structure contains the parameter epsilon that represents the value below which a number will be treated as zero (default value is 1e-12).

R2023b: To be removed

The vrdir2ori will be removed in a future release. Instead, use sim3d classes and Simulation 3D blocks in Unreal Engine Scenario Applications to interface MATLAB® and Simulink® with the Unreal Engine® 3D simulation environment. To get started, see Get Started Creating Virtual World with Actors.
