A header-only C++ math library that mirrors HLSL shading language syntax, including vectors, matrices, quaternions, swizzling, and data packing. It uses SIMD (SSE/AVX, NEON, WASM) for fast, portable math aimed primarily at game developers bridging C++ and shader code.

Use cases

• write C++ math code with HLSL shader syntax
• fast SIMD vector and matrix math in C++
• share math code between C++ engine and shaders
• cross-platform SIMD math for ARM and x86
• quaternion and matrix transformations in games
• pack and unpack color data efficiently

When to choose

• you want HLSL-compatible math syntax in C++ for game or graphics code
• you need portable SIMD-accelerated math across x86, ARM, and WASM
• you want a header-only dependency with no build step

When to avoid

• you need a full game engine or rendering framework, not just math
• your project targets platforms without SIMD extensions or anonymous-union C++ support
• you prefer a general-purpose linear algebra library with non-HLSL conventions
