In these books, Michel A Rohner describes the aliasing problem and the available solutions. Then, he introduces a new approach, Area-Based AA (ABAA), that he invented.
ABAA and MSAA are compared, using analysis and simulation with 4 & 8 subpixels.
The results show that ABAA provides significant improvements over MSAA. ABAA is the best solution to Anti-Aliasing. I produces better images, while being lower cost and lower power.

The MSAA solution has been around for around 40 years. During that time, several approaches
have been proposed, without solving the 3 main problems:
-How to efficiently and accurately detect the covered subpixels.
-How to implement AA without speed (and cost) penalty.
-How to have equal steps as edges move across pixels.
Finally, Michel A Rohner invented the ABAA solution that solves these 3 problems. Because of
its efficiency, simplicity and lower cost, this approach will be widely accepted. With ABAA, the
future video adapters will be better and cheaper.
Instead of sampling Subpixel points inside of a pixel, ABAA computes the area that is partially
covered by polygons within a pixel. It then assigns this area to Subpixel Areas. Unlike MSAA,
ABAA does not require multiple image computations. With ABAA, the covered area can be
evaluated with only one measurement. The ABAA implementation occurs in the last steps of
rendering, where the pixel generation require very fast processing. The ABAA implementation is much faster, less costly and uses less power
An analogic comparison can be used to illustrate the comparison. For example, consider how to move between 2 points A and B in New York city. With MSAA, you use a car and travel through 8 intersections from Point A to Point B. With ABAA, you use the subway and travel non-stop from Point A to Point B.
-Better Image Quality, with less Subpixel samples when compared to MSAA.
-Produce equal steps as edges move cross pixels.
-Edge orientation independent.
-Proposed implementations can be scaled to 4 and 8 Subpixels, and even 16 and 32
subpixels.
-Simpler implementation, lower power and lower system cost.
Michel expects that this new approach will be widely accepted. It should result in improved
image quality and lower cost for future 3D graphics adapters and 3D RT CGI systems.
Michel Alexandre Rohner has many years of experience designing the fastest RT CGI systems with AA. In these books, he reviews the current approaches to AA. Then he introduces a new approach that he invented, Area-Based AA (ABAA). Using analysis and simulation with 4 & 8 subpixels, he shows that ABAA is vastly superior to MSAA, at lower cost. The ABAA implementation described in these books is patent pending, (Provisional Patent Application 63/549,290).
