Visualization Layer Properties

The Visualization Layer contains the data space and, for three-dimensional objects, the lights, associated with a visualization.

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, along with the property identifier and allowed values for use by the iTools Procedural Interface. For a description of how a particular control is used, refer to Property Controls.

Allowed 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)

COLOR

3D integer array of the form:

[R, G, B]

Each color value may range from 0 to 255.

Transparent

Boolean: Make visualization layer transparent? Choose True or False. Default = True

TRANSPARENT

0 (Do not make visualization layer transparent)

1 (Make visualization layer transparent)

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

_PROJECTION

0 (Orthogonal--default)

1 (Perspective)

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.

DEPTHCUE_BRIGHT

Floating point

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.

DEPTHCUE_DIM

Floating point
