Connect Sensor Data to 3D Models

Overview

For more than 20 years, NI LabVIEW software has made it easy for engineers and scientists to create user interfaces and

displays using 2D charts and graphs. LabVIEW 8.6 introduces a new concept for data visualization: 3D sensor mapping.

You can now easily incorporate CAD models into the LabVIEW environment to better show how acquired data

corresponds to the device under test.

Visualize DAQ Channel Data on 3D Models

With the LabVIEW 3D Sensor Mapping Express VI, you can import a user-defined CAD model (VRML or STL file) into

Figure 1. LabVIEW 3D Sensor Mapping Express VI

Using the 3D Sensor Mapping Express VI

Navigate to the 3D Sensor Mapping Express VI in the Functions Palette at Functions>>Graphics & Sound>>3D Picture

Control>>Helpers>>Sensor Mapping.

Figure 2. Helpers Palette with Sensor Mapping Express VI

When you place the Express VI on the block diagram, the configuration window appears. Load your model using the

Model Path file dialog at the top, and your model appears in a large 3D picture control. The LabVIEW 3D Sensor Mapping

Channels List dialog box and release your mouse on the location where you want to place that sensor. You can move the

sensor later by either left-clicking on the sensor and dragging it to a new location or by left-clicking on its name in the

Channels List dialog box and dragging it to the new location on the model.
