poIImagePlane GetCullAngle

Gets the culling angle setting for the image plane.

Syntax

Imageplane_handle GetCullAngle

Application

HyperView Tcl Query

Description

When the image plane mode is 3D, HyperView compares the camera view angle to the image plane’s surface normal. When the difference is greater than the cull angle, HyperView applies transparency to the image plane. The greater the angle difference, the more transparent it becomes. The transparency effect is also multiplied by the Alpha property of the image plane. This command returns the current cull angle value.

Example

To create two image planes, and then query one of them for its basic properties and settings:
