HLSL(High Level Shader Language) is a proprietary shading language developed by Microsoft for use with the Microsoft Direct3D API

HLSL is a C-like language developed by Microsoft and it's used in Direct3D API to define shaders. HLSL is used by Direct3D 9, and is required by the unified shader model in Direct3D 10+.

HLSL can be used to define pixel shaders, vertex shaders, geometry shaders, compute shaders, tessellation shaders, raytracing shaders and mesh shaders. It is analogous to for OpenGL.

Vulkan SDK and DirectX Shader Compiler also supports compiling HLSL shaders into SPIR-V, enabling its use in Vulkan applications.
