Ruler Class

Shape node to display an interactive distance measuring tool.

Preview Feature: 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.

Remarks

This node displays an interactive distance measuring tool on top of an SoOrthoSlice. The user can click and drag to display a line and the physical distance between the clicked point and the current cursor position.

This node is only intended to be used in a "2D" viewing environment using an SoOrthographicCamera, for example viewing a single slice of a medical volume.

This node requires that the application handles mouse press, release and move events. Mouse move events must be forwarded to the node using the ManageMouseMove() method. See MedicalRuler example.
