These properties control the visualization of the data space. For each property, the type of control and the values that can be assigned are listed. For a description of how a particular control is used, refer to Property Controls.

Table D-39: Visualization Layer Properties 
Property
Control Type: Values
Background Color
Color: Visualization layer background color. Transparent must be set to False. Click to choose from the default color palette, or specify RGB values. Default = [255, 255, 255] (white)
Transparent
Boolean: Make visualization layer transparent? Choose True or False. Default = True
Projection
String List: Projection method for displaying the visualization layer. Select a method from the list. Choose from these values:
  • Orthogonal: Orthographic projection (objects are projected onto the visualization layer along lines perpendicular to the view plane)
  •  

  • Perspective: Objects are projected onto the visualization layer along perspective lines that converge in the distance.
Default = Orthogonal
Stretch to Fit
Boolean: Stretch visualization layer to fit window? Choose True or False. Default = False
Depth cue bright
Number: The distance of the near Z plane used for depth cueing. Objects closer than this distance will be painted in their normal color. Objects further than this distance will fade into the background.
Depth cue dim
Number: The distance of the far Z plane used for depth cueing. Objects further than this distance will be painted in the background color. Setting Depth cue bright and Depth cue dim to the same value will disable depth cueing.
