{ "item_title" : "Introduction to Area-Based Anti-Aliasing for CGI", "item_author" : [" Michel a Rohner "], "item_description" : "Computer Generated Imagery (CGI) consists of computer applications for creating images in art, video games and 3D animation. These images consist of 2 dimensional arrays of pixels (picture elements), such as 1kx1k pixels for example. 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.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.This book has three versions and this is the introductory version.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/888/775/9798887759746_b.jpg", "price_data" : { "retail_price" : "38.99", "online_price" : "38.99", "our_price" : "38.99", "club_price" : "38.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
