(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.
Simulink 3D Animation
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.
Output 1 — Output signal
real scalar | real vector
Output signal returned as unspecified, that drives the virtual reality visualization.
Output width — Length of vector
Length of the vector containing placeholder signal values.
