Joe Baldwin

Title: Joe Baldwin and Graphics Display Innovation.

Introduction

Joe Baldwin is an inventor associated with Fort Collins, Colorado, and Hewlett-Packard Company. His patent work addresses a method for displaying polygon edges, or decals, in computer graphics.

Latest Patents

Baldwin is credited with 1 patent: “Method for Displaying Edging or Decaling of an Object in a Graphics.” The invention describes a three-pass rendering process. First, the system renders a polygon’s fill while setting an edging-plane bit for each pixel written to the frame buffer and z-buffer. Next, it renders the polygon’s edges using that bit as a virgin bit. Finally, it re-renders the fill to reset the edging-plane bit for each pixel. The system can also use a virgin bit in the z-buffer as the edging-plane bit.

Career Highlights

Baldwin’s documented patent contribution focuses on graphics rendering, particularly the display of polygon edges alongside filled shapes. The method uses z-buffer operations and per-pixel state to manage the rendering process.

Collaborations

Baldwin’s listed coworkers include Russ William Herrell and Christopher G. Wilcox. His patent is associated with Hewlett-Packard Company.

Conclusion

Joe Baldwin’s patent describes a multi-pass approach to polygon edging that combines frame-buffer and z-buffer operations to support graphics display.
