samples are used. The final result is anti-aliasing with 8X super-sampling quality, for just 2X rendering time on increase (average). Keywords: Rendering, adaptive anti-aliasing, ray-tracing, SIMD, MSAA-patterns. 1. INTRODUCTION . Raster displays use a …
NVIDIA Unveils Adaptive Temporal Anti-Aliasing with Ray-Tracing
https://www.techpowerup.com/246413/nvidia-unveils-adaptive-temporal-anti-aliasing-with-ray-tracing?cp=1
NVIDIA published the first documentation of Adaptive Temporal Anti-Aliasing (ATAA), an evolution of TAA that incorporates real-time ray-tracing, or at least the low light-count method NVIDIA implemented with RTX. Its "adaptive" nature also lets it overcome many of the performance challenges users en...

https://computergraphics.stackexchange.com/questions/4248/how-is-anti-aliasing-implemented-in-ray-tracing
Show activity on this post. After reading a few articles online I can confidently say I am clueless on how Anti-Aliasing works when using Ray Tracing. All I understand is that A Single Pixel/Ray is split into 4 sub-pixels and 4 rays rather than 1.
Anti-aliased and accelerated ray tracing
https://www.cs.utexas.edu/users/fussell/courses/cs384g-fall2011/lectures/lecture10-Aa_and_accel_raytracing.pdf
Antialiasing in a ray tracer We would like to compute the average intensity in the neighborhood of each pixel. When casting one ray per pixel, we are likely to have aliasing artifacts. To improve matters, we can cast more than one ray per pixel and average the result. A.k.a., super-sampling and averaging down.

anteed interval adaptive anti aliasing method ( I AA) for inter- val ray tracing of implicit surfaces. The method is based in the study of the coherence of sets of neighboring rays in a pixel, to...
Adaptive Temporal Antialiasing - NVIDIA
https://research.nvidia.com/sites/default/files/pubs/2018-08_Adaptive-Temporal-Antialiasing/adaptive-temporal-antialiasing-preprint.pdf
We introduce a pragmatic algorithm for real-time adaptive super- sampling in games. It extends temporal antialiasing of rasterized images with adaptive ray tracing, and conforms to the constraints of a commercial game engine and today’s GPU ray tracing APIs.
Improving Temporal Antialiasing with Adaptive Ray Tracing
https://research.nvidia.com/sites/default/files/pubs/2019-03_Improving-Temporal-Antialiasing//Marrs2019_Chapter_TemporalAntialiasingWAdaptiveRays.pdf
Since the base case of TAA is acceptable for most screen pixels, the cost of ray tracing is highly amortized and requires a ray budget far less than one sample per pixel. For example, we can adaptively employ 8× ray traced supersampling for 6% of the total image resolution at a cost of fewer than 0.5 rays per pixel.
