Set Scene Show Filters
Activate the desired scene (click on any of its 3D view windows).
Use the toolbar Show to change the appearance filters for the entire active scene.
Note, the filters of the toolbar Show are working together with (after) the filters of the toolbar Color.
The button "
F" works together with the settings of the "far" attributes of the toolbar Location.
The Scene Show filters
The filters of the toolbar Show are working together with (after) the filters of the toolbar Color.
The three-level system of the appearance filters
All filters of the toolbars Color and Show constitute the entire system with three levels:
Some of the appearance properties can be set on several levels, some other correspond to only one level.
The filters of different levels are working in a sequence, one after another. The level of a particular group of faces has the highest precedence. The level of the entire scene has the lowest precedence.
The toolbar Color deals with individual objects, while the toolbar Show deals with the entire scene. The toolbar Show does not change the object attributes, it only filters which of them to show. Therefore, if any appearance property/option of a particular object or of its face group is switched off in the toolbar Color, it cannot appear in the 3D view window at any state of the toolbar Show filters. In other words, the toolbar Show deal with those properties, which passed through the filters of the toolbar Color.
On two screen shots below, you can see an example how the filters of both toolbars Color and Show are working together.
On the first screen shot, the button "p" of the toolbar Show is unchecked, and the button "h" of the toolbar Color is unchecked, while the line "faces" is selected in the combo box COLOR for the cylinder that is selected in the combo box SCENE. It means that the toolbar Show hides points (vertices) of all the scene objects, and the toolbar Color allows to show the cylinder faces (with the specular reflectivity and the smooth shading) together with their shadows (the buttons "r", "sm", "sr" of the toolbar Color are checked). However, the button "r" of the toolbar Show is unchecked. Thus, the toolbar Show disallows to show the specular reflectivity of any object. Because of these settings, you see the cylinder side faces like a smooth (but not specular) surface on the first screen shot.
On the second screen shot, the button "p" of the Show toolbar is checked, and the button "h" of the toolbar Color is checked. The toolbar Show allows all the points, edges, and faces of all objects to be visible (the buttons "p", "e", "f" of the toolbar Show are checked). However, you see only the cylinder points (the vertices of its top and bottom polygons), because the toolbar Color hides all the faces of the cylinder.
The Filter buttons
Use the button "p" to show/hide points (vertices) of all objects
To show/hide points, check or uncheck the button "p".
You cannot hide points on the level of an individual object, but you can hide all points of all objects on the scene level by the button "p" of the toolbar Show.
Usually, points are shown with the 1-pixel width. However, when both items "edges" and "faces" of the particular object are hidden, the points of that object are shown with the 3-pixel width (see the second screen shot above).
This option helps you to find the object position when you hide the object edges and faces. Usually you do not need to see points (vertices) together with edges and faces. Therefore, in the default state (when you open a new blank scene) the button "p" is unchecked.
Use the button "e" to show/hide edges of all objects
To show/hide edges, check or uncheck the button "e".
Use the button "f" to show/hide faces of all objects
To show/hide faces, check or uncheck the button "f".
Use the button "r" to show/ignore the specular reflectivity for all objects
To show/ignore the specular reflectivity, check or uncheck the button "r".
Use the button "sh" to show/hide shadows of all objects
To show/hide shadows, check or uncheck the button "sh".
In addition, you can show/hide shadows that are provided by individual objects, using the button "sr" of the toolbar Color.
Note, the shadow calculations take much time. These calculations can slow down the rendering (updating) of 3D view windows when you use the spin controls or the keyboard arrow keys to manage a complex scene with many object faces. In such cases, you can hide shadows for a moment, adjust objects as you like, and then show shadows again.
You can see how complex is your scene in the rightmost indicator of the status bar that shows the total number of all object faces. Where is the boundary between "simple" and "complex" scenes depends on the PC hardware.
Use the button "oC" to show/hide the own coordinate system of the object selected in the combo box SCENE
To show or hide the own coordinate system of the selected object, check/uncheck the button "oC".
If the "sh" button is checked but no object is selected (when the combo box SCENE displays its title line "SCENE"), then the 3D view window shows axes of the scene coordinate system.
Use the button "pC" to show/hide the parent coordinate system selected in the combo box REF CS
To show or hide the parent coordinate system, check/uncheck the button "pC" of the toolbar Show.
If the line "scene" is selected in the combo box REF CS, then the 3D view window shows axes of the scene coordinate system.
Use the button "PJ" to show the scene in the perspective or orthographic projection
To show the scene in the perspective projection, check the button "PJ".
To show the scene in the orthographic projection, uncheck the button "PJ".
Use the button "
F" to switch on/off the mechanism that distinguishes "far" and "near" objects
To distinguish "far" and "near" objects, check the button "
To ignore the "far" attributes, uncheck the button "
The Filters in action
You can see on the screen shot below, how a model of an airplane looks when only the button "e" (edges) is checked in the toolbar Show.
Such a wire frame view is useful for some operations. Together with the button "##" ("Object Numbers") of the toolbar 3D View, it makes easy to find an object of a complex scene (to change the object dimensions/location or to attach it to another object).
Finally, you can see on the screen shot below how the airplane model looks in the perspective projection, when all faces with their specular reflectivity and all shadows are visible.
