Maps real-world data onto a 3D model.
Use the Sensor Mapping Express VI to wire an array of data values to represent sensors you configure using the dialog box options below.
|Dialog Box Options|
|Block Diagram Inputs|
|Block Diagram Outputs|
|Load Model||Displays a file dialog box you can use to navigate to a file of a 3D model you create using a CAD program. LabVIEW supports the following file formats for three-dimensional object models:
|Model Path||Specifies the path to the 3D model you want to load.|
|Sensor Canvas||Displays the 3D model. Right-click the 3D model on the sensor canvas to place free sensors. You can configure sensors to represent NI-DAQmx channels or create free sensors to represent data you wire to the Express VI.|
|Draw Style||Determines how LabVIEW draws the 3D model. Use this option to ensure accurate placement of the sensors. Select from the following options:
|Sensor Size||Determines the size of the sensors you place on the 3D model. Use this option to ensure accurate placement of the sensors.|
|DAQmx Task Name||Lists all NI-DAQmx tasks you create and save. Selecting a NI-DAQmx task from the pull-down menu populates the Channels List with the channels for the task. |
|Channels List||Lists DAQ channels and free sensors. Select a DAQmx task from the pull-down menu. LabVIEW populates the Channels List with the channels for the DAQmx task. Drag and drop DAQmx task channels from the list to place sensors on the 3D model. You also can right-click the 3D model to place free sensors on the model.|
|Delete Sensor||Removes a sensor from the 3D model. Select a sensor in the Channels List and click the Delete Sensor button to remove the sensor from the list. Deleting a sensor from the 3D model does not delete the channel from the DAQmx task.|
|Color Ramp||Configures the minimum and maximum value ranges for the incoming data. For example, if you change the color ramp minimum to 100 and the maximum to 200, the data values should range from 100–200. After you set the value range, click the top and bottom out-of-range colors to configure the colors to indicate if a value is outside of the value range you set.|
Right-click the Color Ramp control and use the shortcut menu items to customize the appearance, size, colors, and number of colors.
|Sensor Values||Contains the sensor values. Wire a 1D array of double-precision, floating-point numbers whose positions correspond to the order you configure the sensors in the Configure Sensors dialog box.|
|error in||Describes error conditions that occur before this node runs.|
|Scene Ref Out||Returns a reference to a 3D scene object. Wire this output to the 3D picture control to add a 3D picture control to the front panel window and view the 3D model.|
|error out||Contains error information. This output provides standard error out functionality.|
