Detailed Description

VSG extension (Preview feature) [Medical] Shape node to display a medical gnomon (compass) on the screen.

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
    }
