Checkerboard rendering, rotated anti-aliasing and grid frequencies
This post is inspired by three interesting statements or questions that I heard and are interconnected by non-obvious theory: First was regarding so called checkerboard rendering (example1 example2) – what is advantage of using it? After all it’s the same as … Continue reading

Major C#/.NET graphics framework update + volumetric fog code!
As I already promised too many times, here comes major CSharpRenderer framework update! As always, all code available on GitHub. Note that the goal is still the same – not to write most beautiful or fast code, but to provide a … Continue reading

Poisson disk/square sampling generator for rendering
I have just submitted onto GitHub small new script – Poisson-like distribution sampling generator suited for various typical rendering scenarios. Unlike other small generators available it supports many sampling patterns – disk, disk with a central tap, square, repeating grid. It … Continue reading

Temporal supersampling and antialiasing
Aliasing problem Before I address temporal supersampling, just a quick reminder on what aliasing is. Aliasing is a problem that is very well defined in signal theory. According to the general sampling theorem we need to have our signal spectrum … Continue reading
