VR Placeholder

(To be removed) Send unspecified value to Simulink 3D Animation block

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

Libraries:
Simulink 3D Animation

Description

The VR Placeholder block sends out a special value that is interpreted as “unspecified” by the VR Sink block. When this value appears on the VR Sink input, whether as a single value or as an element of a vector, the appropriate value in the virtual world stays unchanged. Use this block to change only one value from a larger vector. For example, use this block to change just one coordinate from a 3-D position.

The value output by the VR Placeholder block should not be modified before being used in other VR blocks.

To open the Block Parameters dialog box, double-click the block.

R2023b: To be removed

The VR Placeholder 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.
