Title: Innovations by William C Lange
Introduction
William C Lange is an accomplished inventor based in Grass Valley, CA (US). He has made significant contributions to the field of graphics display technology, holding a total of 2 patents. His work focuses on enhancing the user experience in graphics manipulation and display systems.
Latest Patents
Lange's latest patents include the "Reduced viewport for graphics display" and the "Graphics path prediction display." The reduced viewport feature allows operators to observe manipulations on a graphics display of video image planes that are wholly or partially outside a viewing area. This innovation transforms a two-dimensional input image plane into a three-dimensional image plane through manipulation, such as rotation and translation. The resulting three-dimensional image plane is then mapped as a two-dimensional projection onto the graphics display. By multiplying transformation matrix coefficients by a variable reduction coefficient, all points of the image plane converge toward the center of the graphics display, enabling the operator to view previously invisible space on an output video monitor.
The graphics path prediction display features fixed wireframes representing key positions of an image being manipulated. Dots or dashes are generated between these wireframes according to a defined display rate. The in-between wireframes are created by an algorithm selected by the operator and are adjusted in real-time as the operator changes variable parameters. This results in a real-time display of the graphics path defined by the algorithm and parameters.
