Each newly created presentation is displayed in the VTK 3D Viewer. VTK 3D Viewer is described in details in the documentation on GUI module.
To display an existing presentation, right-click on it in the Object Browser and select Show.
Right mouse-click on the Presentation gives access to the following options:
- Note:
- All parameters are context-sensitive: NOT all types of visualization and NOT all properties can be set for a certain 3D presentation.
- Hide all - allows to hide all objects from the viewer.
- Edit - allows to return to the menu, where the presentation has been created and change its parameters.
- Filter by Scalars - allows showing only the cells with values that fit into the defined Scalar Range.
In the dialog box, check in Filter by scalar range box and input the minimum and the maximum values for the Scalar Range.
- Rename - allows to rename the presentation.
- Copy - allows to create a copy of the presentation in the same subfolder (time stamp) in the Object Browser.
- Values Labeling allows to display values applied to the cells or nodes of a 3D presentation.
- Labeling Parameters allows to change such labeling parameters as font and color.
- Hide - allows to hide the selected presentation from the viewer.
- If selected in the Object Browser, Hide is replaced by Show, which allows to display the selected presentation in the viewer.
- Show Only - allows to display only the selected presentation, hiding all other from the viewer.
- Hide Scalar Bar/Show Scalar Bar - allows to show/hide the scalar bar attached to the 3d presentation.
- Representation - allows to switch among the available representation types.
- Points
- Surface
- Wireframe
- Insideframe - displays the wires lying within the object
- Surfaceframe - displays wires and cells lying on the object surface
- Feature edges - shows the contour of the object
- Shrink
- Shading on - colors the object in a realistic way, revealing its geometry, for example, by applying shadows to the inside regions; used together with Surface.
- Shading off - colors the object basing only on scalar values.
- 2D Quadratic - allows to choose how the quadratic elements are visualized: as straight lines or as arcs of circle.
- Properties
- Opacity - allows to set the value of opacity of the presentation between 0 (transparent) and 100 (opaque).
- Note:
- For a Gauss Points presentation, displayed using Point Sprites or OpenGL Points primitives, this property only allows switching between transparent and opaque modes. The textures are drawn in the opaque mode if the opacity is equal to 100% and in the transparent mode if the opacity is lower that 100% (note that they become invisible when the opacity is equal to 0%).
- Line Width - allows to set the width of lines representing edges of the presentation between 1 (thin) and 100 (thick).
- Shrink Factor - allows to set the shrink factor of the presentation to be used in Shrink mode. Possible values range between 20 and 100, the default value is 80.
- Edge Color - allows to set the color of lines representing the edges of the presentation displayed in SurfaceFrame mode.
- Translate Presentation - allows to translate the presentation along coordinate axes.
- Clipping Planes - allows to create cross-section views of presentations.
- Sweep - allows to display pseudo-animation of the presentation.
- Dump view - exports an object from the viewer in bmp, png, jpg or jpeg image format.
- Change Background - allows to change the properties of the background.
- View Operations checkbox - shows or hides the VTK viewer toolbar. The information about the VTK viewer functionalities is available in the documentation on the GUI module.
- Recording operations checkbox - shows or hides buttons used for Recording.
The following menu items are added when the presentation is selected in the Object Browser.
- Delete - removes the presentation from the study.
- Refresh - updates the presentation in the VTK viewer.
- Find - activates Find Tool described in the documentation on GUI module.
When you create several presentations of the same object, you may wish to see them simultaneously, which might be impossible, because they all are located at the same place. To solve this problem, right-click in the viewer and select Arrange Actors in the pop-up menu.
In Auto mode you specify along which Axis and at which Relative Distance the presentations should be lined up.
In Manual mode you set the coordinates for each presentation separately.
Displaying several presentations at the same time may cause superposition of their scalar bars. To avoid this, check Arrange Scalar Bars radio button in the Preferences -> Post-Pro -> Scalar Bar. A separate scalar bar will be displayed for each presentation.
Alternatively you may wish to merge the scalar bars to have a common scalar bar for all presentations. To do this, select several presentations or fields in the object browser, right-click and from the pop-up menu select Merge Scalar Range.
To restore separate bars and scales for each module select Use Field Range from the same menu.
