The Slide Show feature was first introduced in ParaViewGeo version 1.4.2. The feature was created to help make presentations using ParaViewGeo. The features goal is to provide a means of storing a number of 3D views in a slide show, saving these views in a State File and then providing a means to cycle through each view. This provides the same features as Microsoft's PowerPoint, while still allowing each view to be rotated, zoomed etc.
The views are easily loaded into the View Manager and can be updated, renamed, re-arranged and deleted. The Slide Show feature is comprised of the Slide Show pane and the Slide Show toolbar, both of which are accessible through the View menu. The Slide Show toolbar displays the available slide tools and is used to store the visual representations generated in the View Manager. The slides are not images but a view location and a copy of each object's visibility and properties. Thus, unlike an image, each slide can be rotated, zoomed and objects can be turned on and off. The slides that have been created are visible in the Slide Show pane, and selecting a slide from the pane will display it in the render window. Please note that the slide show feature is only intended for 3D views. Creating, Updating and Deleting SlidesWhen you have created a view in the render window that you'd like to save as a slide, click on the Add Slide icon (or Ctrl+T). You'll be prompted for a slide name (it says SlideShow, but is just for the slide), and the slide will be added to the Slide Show pane. This also works if you have multiple render windows in use; the slide will show all the windows. If you now make additional changes in the render view, you can always revert to the saved view by clicking on the slide in the pane. The other option is to save the new changes you've made. There are two choices, either you can update the current slide to show the new changes by clicking the Update Slide icon (or right-clicking on the slide in the pane and selecting Update), or you can make a new slide with the Add Slide button to keep both views. Another way of creating a new slide is to use the Import File and Create Slide button available since version 1.4.10. You can use this option to import any kind of supported file, such as datasets that are not yet loaded into the pipeline, or even images you want to use on a slide. Whatever file is loaded will become visible in the currently active render view, and you'll be prompted for a slide name. There is no need to Apply the load in the Object Inspector, as this is done automatically.
If you change your mind and decide that one of the slides you've created is no longer required, select that slide and either right click on it or click the Delete Slide button to remove it from the pane. If you accidentally delete a slide, there is no way to bring it back. Neither of the Undo functions can re-create that slide. To delete all the slides, open the Edit menu and choose Delete All Slides.
Reducing the Number of Render ViewsIf you have created one or more slides that use multiple render windows, and now want to create a slide that has less views, you cannot simply close one (or more) of the render views, as this would break the connection with the slides that already exist. A message will appear stating that all linked slides will be deleted if the view is closed. Prior to version 1.4.14, this message did not appear if a view other than a 3D view was removed, but once removed, any slides containing that view could not be re-created. Since Slide Show is designed to work only with the 3D view, starting with version 1.4.14 if you try to save a slide that contains a different view a message will appear indicating that only 3D views are supported and the other view will not be saved as part of the slide. Instead of deleting a view, you can hide one or more of the views so that they are not visible in the View Manager. To hide a render window you have to use one of the inside edges of that view to resize it until it disappears. For instance, in the image below, we want to hide the bottom left view. Move the cursor between the bottom left and middle windows, and when the double-arrow cursor appears (outlined in red in the image), drag the edge of the window all the way to the left side, until the view disappears, leaving a slightly thicker border. The render window is now hidden at the edge, but still exists; to bring it back, move the mouse to the edge until the cursor changes, and drag the window back out. You cannot hide a window that currently sits between two other windows. So if we wanted to hide the bottom middle window only, it cannot be done. Instead, we can switch that window with one of the others (say the bottom left again) by clicking on the menu bar of the middle window and dragging it over the left window. This switches the views, and now the left window can be hidden as explained above. Note: All slides will be affected if a render view is added or hidden, and also if the size of a render view is changed. All slides in the presentation should contain the same number of render views, though it is possible to change the size of the views, including hiding and showing a render view, during a presentation.
Slide PresentationsSlide Show can be used to create presentations that are similar to PowerPoint presentations but still allow interactivity with objects on the slides while the show is presented.
Adding TextPowerPoint presentations usually have pages of bulleted text, or at least a title at the top of the page. ParaViewGeo doesn't really allow bulleted text on the slides, but there are several options that can be used to add text. One way to add text is to use the options from the Sources menu. The two that apply are 3D Text and Text.
You can also import pictures that contain text. For instance, if you want a true theme and bulleted look you can create the slides in PowerPoint, take screenshots, and then use the Import File and Create Slide button to add the slides in Slide Show. Caution!! These 'slides' are now objects and will rotate/zoom in Slide Show, and if changes need to be made to the text, they will have to be made in PowerPoint and the slide will need to be re-added to Slide Show. Hint: Use simple themes, you will probably need to adjust the View Settings for the background and headlight so the slide matches your show.
