Antialiasing
From WhiteWing
Morphological Antialiasing
- Post-processing step in ray tracing applications, completely independent from the rendering pipeline
- A new antialiasing algorithm which is based on recognizing certain patterns in an image
- Inspired by a computer vision algorithm, morphological image analysis (Soille and Rivest 1993)
- Inable to handle features smaller than the Nyquist limit
Previous Works
- Among the advantages of algorithms which use object silhouettes is that such algorithms provide a way to reliably find discontinuities inside pixels. At the same time, discontinuities due to different materials will not be found through silhouette tracing. Furthermore, silhouette-based techniques cannot remove aliasing in reflections or refractions, as these algorithms require a single center of projection (camera or light source) to determine what a silhouette is.
