## Description

This project is a reference library of HLSL shader implementations and source code examples for Unity. It provides a collection of practical samples focused on lighting, coordinate transformations, and rendering passes for 3D graphics.

The repository demonstrates the application of 3D rendering mathematics, specifically using vector and matrix calculations to determine light directions and coordinate space transformations. It includes implementations for managing multi-pass rendering pipelines and mapping coordinates between object, world, and view spaces.

The material covers foundational graphics rendering capabilities, including linear algebra for vector-to-matrix transformations, lighting and shading calculations for surface brightness, and the interaction between vertex and fragment shaders.
