VR Placeholder - Send unspecified value to Virtual Reality Toolbox block

Library

Virtual Reality Toolbox

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.

Data Type Support

A VR Placeholder block outputs signals of type double.
