Use 3D models to display data as coloring or as deformation on a 3D model of the test object. For example, 3D models display the temperatures in a vehicle as color shading on a dummy or display strain as deformation of a bridge support.
If you select Display Type»3D Model from the shortcut menu, DIAdem displays a model area and opens the Dialog box for the selection of a 3D model. Select the 3D model of the test object in this dialog box. Double-click the empty model area to open the selection dialog box or select Select 3D Model from the shortcut menu. You can use 3D models in VRML2 (Visual Reality Modeling Language) format and in STL (StereoLithography) format. DIAdem does not support the VRML1 format. When DIAdem loads the model file, DIAdem can exchange the y-axis and the z-axis to adjust the alignment of the 3D model.
After loading the model file you connect your Channels with the model points to project your data onto the 3D model. The channels contain the measurement values that a sensor that is connected to the surface of the test object recorded.
Select channels in the Data Portal and drag and drop these channels onto a point on the 3D model to assign data to the 3D model. Specify in the shortcut menu of the model point whether DIAdem displays the data as coloring or as deformation of the model surface.
Use the Coloring display, for example, to display temperature changes on the 3D model as color shading. Use the Deformation display to display movements of the model surface. You can combine several display types in one model. For example, you can display temperature simultaneously as color shading and as deformation. To do so, assign the same data channel twice to one model point, with a different display type each time. The tooltip of a model point shows which display type and which data channel you used to define the point.
The model points that you assign data to become sensor points. DIAdem identifies these points on the 3D model with points. If you assign a data channel to the incorrect model point, press <Shift> and drag and drop the definition to the correct model point. Use <Ctrl-Shift> to copy a definition. Select Delete Sensor, Delete All Sensors, or Delete Invalid Sensors from the shortcut menu of the 3D model to remove one or more sensor points.
Select Display from the shortcut menu of the 3D model to configure the projection of the data onto the 3D model. On the Sensor List tab you specify which data DIAdem projects onto the 3D model and how DIAdem displays the data. Select the Display tab to specify the display of the basic model and also the settings for the surface coloring and the deformation. DIAdem can display the base model as points, as lines, as surfaces, as color surfaces, or as a combination of these options. This also applies for the deformation model which DIAdem only displays when you assign the Deformation display mode to a channel. Specify the value range to which DIAdem applies the color shading. DIAdem can display the coloring you specify on the base model and on the deformation model.
If you select Deformation, DIAdem displays a copy of the 3D model set in the offset directions. During an evaluation you can compare this deformation model directly with the unchanged basic model.
If you select Coloring, a color legend automatically appears in the bottom area. The default color palette that DIAdem uses, comprises the colors blue>green>yellow>red. Select User-defined coloring in the Projection onto 3D Model - Display » Display dialog box to define your own Color Palette.
You can move and zoom the 3D model to view it from all sides. To rotate the 3D model, click and drag the mouse. To resize the 3D model, right-click and drag vertically. You also can use the mouse wheel to resize the 3D model. To move the 3D model along a coordinate axis, right-click and press <x>, <y>, or <z> at the same time to choose a coordinate axis. At the bottom right in the model area, you see a small coordinate system that shows the position of the model in space.
Select Alignment from the shortcut menu of the 3D model to view the 3D model on an xy-plane, an xz-plane, or a yz-plane.
To run an animation of the 3D model you can select Play, Repeat Play, Pause, and functions for fast forward or fast reverse, and step-by-step forward or step-by-step reverse, on the toolbar. If your layout contains a 3D model and an axis system, and you move the cursor across the axis system, DIAdem runs the animation of the 3D model synchronously to the cursor. The cursor position specifies which channel values DIAdem projects onto the 3D model.
For model points with no sensor, DIAdem interpolates the values from the data of the neighboring sensor points.
