The article presents a collection of useful mathematical functions and their plots that can be applied in graphics for filtering or smoothing signals. Each function is defined for input values within the range of [-1, 1] and includes variations based on different parameter values. The emphasis is on providing visual representations to aid understanding of these functions.

The article presents the TT_Rasterizer, a TrueType font rasterizer developed in C, which operates without third-party dependencies and supports various colorization modes. It details its capabilities and limitations, including performance issues and the absence of support for certain font features and languages. The library is primarily tested on Windows and aims to improve performance in future versions by potentially incorporating threading and optimizations.

The article discusses the process of rendering a Bézier surface, explaining the mathematical concepts behind it and providing practical implementation details. It highlights the importance of Bézier surfaces in computer graphics and offers examples to illustrate the rendering techniques. The article serves as a guide for developers looking to understand and apply these concepts in their projects.

The article discusses the concept of dithering, a technique used in graphics programming to approximate colors when displaying images on devices with limited color capabilities. It explores eleven specific dithering algorithms, including the famous Floyd-Steinberg algorithm, and highlights the importance of dithering in both practical and artistic contexts, such as web design and printing. Additionally, it explains the fundamental principle of error diffusion in dithering.
