Figure 12: The "Display Style" interface can be used to set display options for individual objects. Setting attributes such as single-sided display, and faceted shading, are useful for VR
The "Display Style" interface has the following selections:
Draw Style
This option sets the drawing style of the selected object. This is different from the "Draw Style" specified in the viewer's pop-up menu in that it changes the intrinsic style for a particular object, rather than the overal style for a particular viewer. This draw style is recorded as part of the scene and is written out to the 3D file.
Shaded
In this mode, the (selected) objects appear filled.
Wireframe
In this mode, the (selected) objects are drawn as non-filled lines. Objects are drawn at a faster rate than in "Shaded" mode.
Points
In this mode, the (selected) objects are drawn as points representing the vertices of the objects. In this display mode, objects are drawn at a faster rate than in "Wireframe" display mode.
Bounding Box
In this mode, the (selected) objects are represented as simple boxes. This display mode is the fastest of all modes and is useful to have for objects that you are not currently editing.
Shading
This option is used to set the type of shading to be used while displaying the objects in "Shaded" draw style mode. This menu is not active when the "Draw Style" option is set to "Wireframe" or "Points" or "Bounding Box", or if the object is not polygonal (of type "Primitive", "3D Text" and so on).
Smooth
When this option is selected, Ez3d displays the object smoothly shaded. One normal is used for each vertex of the object.
Faceted
When this option is selected, Ez3d displays the object as facets by using a different normal for each face of the object, so the overall object looks faceted.
Hint: For VR, the "Faceted" option will be much faster, even though the smoothness may be less acceptable.
Show Sides
Outside
Only the outside of the object is lit.
Inside
Only the inside of the object is lit.
Both Sides
Both sides of the object are lit. This option can be twice as slow as the other two.
Hint: In VR, it is almost a norm to either use "Outside" or "Inside" - the navigation typically happens on the inside of an object (such as a room), or outside (such as table). At the end of your scene composition, it may be a good idea to select all objects that show off only their outside, and set the "Outside" option, then do the same for all "Inside" objects.
Line Width
This slider sets line width of objects in "Wireframe" or "Bounding Box" display mode. The default line width value is 1.
Create Angle
This slider sets the crease angle to be used for displaying the object. The crease angle is the minimum angle between two adjacent face normals required to form a sharp crease at the edge when default.
Hint: Use "Crease Angle" to define the sharp edges in the object. A larger crease angle means that the object has fewer sharp edges. This option is also used in conjunction with the "Reduce" tool in "Face Builder".
Use As Default
When you select this option with display options set (such as "Wireframe" and "Line Width"), Ez3d will use these display mode settings for all objects you create thereafter.
