Lightbeam Sensor
The Lightbeam sensor in Omniverse Isaac Sim uses PhysX based raycasts to determine if a beam has been hit by an object.
Users can specify number of rays and height to create a light “curtain” of lightbeam sensors.
See the Isaac Sim Conventions documentation for a complete list of Omniverse Isaac Sim conventions.
Isaac Example
Lightbeam Sensor Example: Isaac Examples > Sensors > Lightbeam
To run the example:
Go to the top menu bar and click Isaac Examples > Sensors > Lightbeam.
You should now see a window containing empty data for each lightbeam, which will be populated with data once you press play. It will show if each beam was hit, the linear depth of the hit, and the exact hit position in xyz.
Press the
PLAY
button to begin simulating.Press
SHIFT + LEFT_CLICK
to drag the cube or sensor around and see changes in the readings.
