Introduction to Area-Based Anti-Aliasing for CGI

When images are computed using a single sample per pixel they show aliasing artifacts such as stairsteps on feature edges (jaggies). Aliasing artifacts can be minimized by applying Anti-Aliasing (AA) techniques such as Multi-Sample AA (MSAA). With MSAA several images are computed for a few sample points per pixel followed by images averaging. MSAA is computation intensive slow costly and with mixed results.</span></p><p><br></p><p><span style=background-color: rgba(255 255 255 1); color: rgba(34 34 34 1)>The author has developed a new approach to AA Area-Based AA (ABAA) that is vastly superior to MSAA. ABAA relies on subpixel area-sampling instead of point-sampling. It produces better quality images. It is also much faster simpler low-power and low-cost. With all these advantages ABAA should be widely accepted for future 3D CGI implementations.</span></p><p><br></p><p><span style=background-color: rgba(255 255 255 1); color: rgba(34 34 34 1)>This book has three versions and this is the introductory version.</span></p>
