## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3056, "days_push": 3052, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A preserved archive of the companion CD source code for NVIDIA's GPU Gems books 1 through 3, containing C++ and HLSL/GLSL sample implementations of classic real-time rendering techniques. Chapters cover water simulation, shadow volumes, grass rendering, GPU fluid dynamics, geometry clipmaps, and image processing frameworks.

## Use cases
- download GPU Gems book companion source code
- learn classic real-time rendering techniques
- study water simulation and caustics shader examples
- learn HLSL and GLSL shader programming through working demos
- find reference implementations of shadow volume and shadow mapping algorithms
- study GPU-based fluid dynamics example code
- see terrain rendering with geometry clipmaps in practice

## When to choose
- You are studying the GPU Gems 1-3 books and want the exact sample code for each chapter
- You want reference implementations of classic rendering effects like water, soft shadows, depth of field, or waving grass
- You are researching the history of GPU programming or porting early-2000s shader techniques to modern APIs

## When to avoid
- You need a maintained, licensed component for a production project - this collection has no license attached and consists of per-chapter demo snippets
- You work with modern GPU APIs like Vulkan, DirectX 12, or CUDA - the code targets era DirectX 9 and early OpenGL
- You expect a buildable unified framework rather than loosely organized chapter demos with dated tool dependencies
