## What it is
glam is a fast linear algebra library for Rust providing vectors, matrices, quaternions, and affine transformation types for games and graphics. It leverages 128-bit SIMD (SSE2, NEON, simd128) for high-performance math on x86, ARM, and WebAssembly targets.

## Use cases
- 3d math for a game engine in rust
- vector and matrix operations for graphics programming
- quaternion rotations for camera and physics
- simd-accelerated linear algebra in rust
- affine transforms for 2d and 3d rendering
- math library for a wasm game or graphics app

## When to choose
- you need fast, simd-optimized vectors, matrices, and quaternions in Rust
- you are building a game, renderer, or physics simulation in Rust
- you need a wide range of scalar types (f32, f64, integer, bool vectors)
- you target x86, aarch64, or wasm and want SIMD by default

## When to avoid
- you need arbitrary-precision or symbolic math
- you need GPU shader math rather than CPU-side math
- you need n-dimensional or sparse linear algebra like nalgebra/lapack features
- you require a stable portable SIMD path on stable Rust

## Facets
- artifact type: library
- maturity: stable
- function: math, graphics, simulation
- domain: graphics, performance
- platform: rust, cross-platform, wasm
- tags: linear-algebra, simd, vectors, matrices, quaternions, 3d-math, game-math, game-development, algorithms, gpu
