Anti‐aliased Ray Tracing with Covers Thomas, D.; Netravali, Arun N.; Fox, D.S. 1989-12-01 00:00:00 A fast and effective object space method for antialiasing ray‐traced pictures is introduced. Traditionally, anti‐aliasing has been done using super‐sampling. However, this is costly since it requires casting large numbers of rays to obtain ...

Ray tracing with cones (Amanatides): Instead of using an infinitely thin ray, each ray is instead approximated by a cone, say with a diameter that covers all of the pixel (and a little of the neighbours) allowing you to do evaluate partial coverage. It also has benefits for texture sampling/antialiasing, soft shadows, and potentially LOD of models.

Simple Ray Tracing in C# Part IV (Anti-Aliasing)
https://www.codeproject.com/Articles/19981/Simple-Ray-Tracing-in-C-Part-IV-Anti-Aliasing
Introduction. Anti-aliasing is the name for techniques designed to reduce or eliminate the jagged effect of square pixels attempting to approximate curved shapes. Here we focus on shading the pixels using an averaging algorithm, adding anti-aliasing to our basic ray tracing. For this, instead of only one ray per pixel, we will fire 4 extra rays ...

Combining the beam-tracing technique with Duff’s exact polygon convolution algorithm may give the most sophisticated rendering algorithm in which antialiasing can be performed by exact symbolic prefiltering. 2.3. Ray Tracing with Covers Another approach to symbolic prefiltering is to filter the objects instead of the ray. One way of doing ...
RayTracing: Aliasing Vs Antialiasing – Graphic PIZiadas

RayTracing: Aliasing Vs Antialiasing. Tour theoretical line on screen. To generate a synthetic image, such as those used in films as Avatar, can produce unwanted effects or "artifacts" that impoverish the image. One such effect is called " Aliasing ”. Aliasing occurs mainly in lines and edges of straight lines, having a shape "sawtooth" that ...

Anti-Aliased Ray Tracing with POSIX Threads Michael Tichenor David Naviaux Oregon State University ECE572 05/29/10 Abstract Ray tracing is a technique developed in the late 1960s to visualize 3D objects with computers. With the advent of GPGPUs and multi-core CPUs, real-time rendering of ray-traced scenes is becoming a very real possibility.
