Abstract
A model controller includes a trackball having a spherical surface with one of latitudinal or longitudinal data tracks formed thereon. The model controller includes a base unit including a first image sensor adjacent to the trackball to capture images of the data tracks, wherein the captured images of the data tracks include orientation information to determine an absolute orientation of the trackball.
Claims15
A model controller, comprising:
- a trackball having a spherical surface with one of latitudinal or longitudinal data tracks formed thereon;
- and
- a base unit including a first image sensor adjacent to the trackball to capture images of the data tracks, wherein the captured images of the data tracks include orientation information to determine an absolute orientation of the trackball.
A method for manipulating a three-dimensional (3D) model, the method comprising:
- capturing an image of a trackball having one of latitudinal or longitudinal data tracks formed thereon;
- identifying orientation information contained in the data tracks in the captured image;
- determining an absolute orientation of the trackball based on the identified orientation information;
- and
- manipulating a display of the 3D model based on the determined absolute orientation of the trackball.
