raytracing - Anti-aliasing / Filtering in Ray Tracing
https://computergraphics.stackexchange.com/questions/2130/anti-aliasing-filtering-in-ray-tracing
In ray tracing / path tracing, one of the simplest way to anti-alias the image is to supersample the pixel values and average the results. IE. instead of shooting every sample through the center of the pixel, you offset the samples by some amount. In searching around the internet, I've found two somewhat different methods to do this:
Anti-aliased and accelerated ray tracing

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.
RayTracing: Aliasing Vs Antialiasing – Graphic PIZiadas
https://piziadas.com/en/2010/02/raytracing-aliasing-vs-antialiasing.html
These techniques are called "antialiasing”. Sampling frequencies liitan these effects are known as "Nyquist frequency Here you have a collection of images that compare visually the same scene rendered using a simple ray tracing of three levels of recursion, and applying a technique supersampling to reduce aliasing of lines.

Anti-aliasing is the name for techniques designed to reduce or eliminate the jagged effect of square pixels attempting to approximate curved shapes. Aliased curve Here we focus on shading the pixels using an averaging algorithm, …

Anti-aliased-Ray-Tracing A ray tracing system which parses 3D scene described with orientation of geometric primitives and allows the user to explore in real-time the CPU based ray traced scene with ultra high realism. Features CPU based ray tracer built from scratch. Users can explore the ray-traced world in real-time using keyboard control.

Stochastic Ray Tracing / Distibuted Ray Tracing Statistical Supersampling What Aliasing Is Due to the fact that the world is sampled and then rendered, possibilities for errors exist. Depending on how the samples are taken, multiple worlds can actually serve as aliases for one another and produce exactly the same sample set.
