## Description

PostProcessing is a post-processing stack for the Unity game engine designed to apply image-space visual effects and color grading to rendered scenes. It functions as a real-time image effect pipeline that processes frames after the primary 3D geometry has been drawn.

The system includes a screen space visual effects library and an HDR color grading toolset used to adjust high dynamic range colors and contrast. These tools allow for the application of real-time image filtering to modify lighting, colors, and mood.

The framework supports 3D scene post-processing and game environment polishing by layering multiple full-screen shader passes. This includes the use of volume-based parameter interpolation to blend visual settings based on camera position within a scene.
