public class Gnomon
extends SoAnnotation

(Preview Feature) Shape node to display a medical gnomon (compass) on the screen.

Preview Feature means this class is fully supported and can be used in Open Inventor applications. Being tagged as a Preview Feature just means that the implementation is still subject to API changes and adjustments based on feedback from early adopters. Please be also aware that source compatibility might be broken regardless of the Open Inventor compatibility changes policy due to our commitment to bring needed changes to be sure the specifications of this Preview Feature match the expectations of our customers.

This node displays a medical specific "gnomon" (compass) on the screen that shows the user the current orientation of the volume in 3D space. Visibility of the gnomon is controlled by the isDisplayed field. Position and size of the gnomon are specified in pixels using the position, width and height fields.

File format/default:

Gnomon {

isDisplayed	TRUE
position	0 0
width	100
height	100

}
