Lecture #13: Anti-aliasing
Computer graphics in Game development
If a function $x(t) $contains no frequencies higher than \(B\) hertz, it is completely determined by giving its ordinates at a series of points spaced \(1/2B\) seconds apart.
Super sampling anti-aliasing
- Trace more than 1 ray per pixel
- Blend resulted colors
- Implement super-sampling anti-aliasing
- Check the quality
What is the new knowledge?
- SSAA is easy to implement
- SSAA is the most expensive way
