Detailed Description

(Preview feature) [Medical] Shape node to display a magnified view of a region of the screen.

This node displays a circular magnified (zoomed in) view of the screen region under the center of the circle. The magnifier is an SoTranslate2Dragger so the user can click and drag to move it around the screen.

Limitations:

• Can only be used in a "2D" viewing environment using an SoOrthographicCamera.
  For example viewing a single slice of a medical volume.
• Can only be used with the default camera orientation (looking toward -Z).

FILE FORMAT/DEFAULT

Magnifier {

sceneToMagnify	NULL
magnifierColor	0 0.6 0
magnifierFactor	50
