Bilinear texture filtering – artifacts, alternatives, and frequency domain analysis
In this post we will look at one of the staples of real-time computer graphics – bilinear texture filtering. To catch your interest, I will start with focusing on something that is often referred to as “bilinear artifacts”, trapezoid/star-shaped artifact … 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
