PhysX SDK Lightbeam Sensor#

The PhysX SDK Lightbeam sensor in NVIDIA Isaac Sim uses PhysX SDK raycasts to determine if an object has intersected a light beam. Users can specify number of rays and height to create a safety light “curtain” of lightbeam sensors.

See the Isaac Sim Conventions documentation for a complete list of NVIDIA Isaac Sim conventions.

Examples#

  • PhysX SDK Lightbeam Sensor Example: Robotics Examples > Sensors > Lightbeam

To run the example:

  1. Activate Robotics Examples tab from Windows > Examples > Robotics Examples.

  2. Click Robotics Examples > Sensors > Lightbeam.

  3. 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.

  4. Press the PLAY button to begin simulating.

  5. Press SHIFT + LEFT_CLICK to drag the cube or sensor around and see changes in the readings.
