Methods for Quantifying and Characterizing Errors in Pixel-Based 3D Rendering

July 1, 2008
Author(s)
John G. Hagedorn, Judith E. Terrill, Adele P. Peskin, James J. Filliben
We present methods for measuring errors in the rendering of three-dimensional points, line segments, and polygons in pixel-based computer graphics systems. We present error metrics for each of these three cases. These methods are applied to rendering with

John G. Hagedorn, Steven G. Satterfield, John T. Kelso, W. Austin, Judith E. Terrill, Adele Peskin
We describe a method for calibrating an electromagnetic motion tracking device. Algorithms for correcting both location and orientation are presented. In particular, we use a method for interpolating rotation corrections at scattered data points that has
