JOY-STICK LIKE GRAPHICAL USER INTERFACE TO ADJUST 3D CROSS SECTIONAL PLANE IN 3D VOLUME

摘要

Methods for a joy-stick graphical control in 3D space are disclosed. 3D data are rendered with a certain orientation in a 3D rendering space within a region of a 2D screen. One or more cross sectional views of the 3D data are rendered in the 3D rendering space where the cross sectional views are derived based on corresponding one or more 3D planes cutting through the 3D data at a 3D location. On one 3D plane, a joy-stick control is rendered in the 3D space at a pose determined based on the joy stick.
