Class: vrfigure

(To be removed) Check validity of vrfigure object handles

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


valid_handles = isvalid(vrfigure_vector)


valid_handles = isvalid(vrfigure_vector) detects whether the vrfigure handles are valid.

Input Arguments

expand all

Virtual reality figure vector, specified as a vrfigure object.

Output Arguments

expand all

Virtual reality figure image, captured as a logical array. The array that contains a 1 where the vrfigure handles are valid and returns a 0 where they are not.

Check whether the figure handles of the vrfigure object are valid. The first check shows that the figure handle is valid, but the second check shows that the handle is invalid because the figure is closed.

myworld = vrview('vrpend');
f = vrfigure(myworld);
firstCheck = isvalid(f)
firstCheck = logical


secondCheck = isvalid(f)
secondCheck = logical

R2023b: To be removed

The isvalid will be removed in a future release. Instead, use sim3d classes and Simulation 3D blocks to interface MATLAB® and Simulink® with the Unreal Engine® 3D simulation environment. To get started, see Create 3D Simulations in Unreal Engine Environment.
