Show and hide 3D objects, slices, contours, dot sets and paths

To show or hide an object right click on it in the Object Explorer and select Show or Hide in the context menu (see also how to display the context menu directly from the 3D scene.) Alternatively, select the object in the Object Explorer and click  that appears on top of the Object Explorer to show the object, or  to hide it (see Figure 2). When an object is shown, all the  dot sets and the path associated to it are also shown automatically.

When trying to show an object whose 3D model has not yet been generated, or it is out of date, a progress dialog box as in Figure 1 appears, while BioVis3D computes the 3D model of the object.

Following a similar procedure, show and hide slices, contours , dot sets and paths. The buttons on top of the Object Explorer to show them are , ,  , and to hide them , , respectively.

Show and hide all the objects in a specific category by right clicking on the category in the Object Explorer and selecting Show All Objects or Hide All Objects from the context menu, too. Alternativelly, select the category in the Object Explorer and click  or , that appear on top of the Object Explorer, to show or hide all the objects of the category respectively.

In the context menu displyed when right clicking on an element in the Object Explorer, there are also options to show and hide several elements in one single operation. For example, Show/Hide Contours and Show/Hide Dot Sets are available options when right clicking on an object. Also the options Show All and Hide All apply in general to all elements (excluding slices) that descend from the right clicked element in the tree of the Object Explorer. For example, Show All applied on object “rele28” of Figure 2, shows the object itself together with all its contours.

The same color / gray pictures used as buttons on top of the Object Explorer to show and hide different elements of the scene, are used as icons in the tree of the Object Explorer to distinguish visible from non visible elements. For example, in Figure 2, the objects “rele28” and “mp3” are visible and so are the slice number 12 and the contour named “NewContour8” of the slice number 11. Other elements in the Object Explorer such as object “rele27” and slice number 11, whose icons are grayed, are not visible in the scene. When the 3D model of an element that is visible in the scene is out of date, its icon in the Object Explorer presents an exclamation mark as object “mp3” in Figure 2. The icons for objects, slices, contours, dot sets and paths that are out of date are , , , ,  respectively. See Update 3D Models for information on how to update them.
