HLSL++ is a header-only C++ math library designed to replicate the syntax and functionality of the HLSL shading language, making it easier for developers to write CPU-side code that mirrors GPU shader logic. It provides vector, matrix, and math operations with a syntax identical or very similar to HLSL, allowing seamless transition between shader code and application code. The library is optimized for performance and supports SIMD instructions across multiple architectures, including SSE, AVX, AVX2, AVX512, and ARM NEON, ensuring high efficiency on modern hardware. It also extends beyond standard HLSL capabilities by introducing additional features such as quaternion support, advanced matrix operations, and extended vector types like float8. The library is particularly valuable for game developers who need consistency between CPU and GPU computations, reducing errors and improving maintainability.

Features

  • HLSL-like syntax for vectors, matrices, and math operations
  • Header-only design with no external dependencies
  • SIMD optimization across multiple CPU architectures
  • Extended math features including quaternions and advanced matrices
  • Support for extended vector types like float8
  • Portable across desktop, mobile, and WebAssembly environments
