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.

How do I get Visual Studio 2017 / msbuild to use the latest DirectX shader compiler?

I'm trying to compile a C# game project which utilizes HLSL shaders. These shaders are part of the .csproj project, and therefore Visual Studio is supposed to compile them along with the code. The shader properties should be correct - shaders are of…

DirectX 11 What is a Fragment?

I have been learning DirectX 11, and in the book I am reading, it states that the Rasterizer outputs Fragments. It is my understanding, that these Fragments are the output of the Rasterizer(which inputs geometric primitives), and in-fact are just…

Can I use a bias value outside [0, 1] for SampleBias in HLSL?

The doucment SampleBias said that Bias is a floating-point number between 0.0 and 1.0 inclusive. However I have done a little experiment and Bias values outside [0, 1] work fine. Is Bias value outside [0, 1] guaranteed to work? Or this just depends…

Inputting Position Into the Pixel Shader

In most of the programs I have seen that make use of vertex position data in the Pixel Shader, there is a tendency to process it as a float4 vector. This restriction does not appear to be present fin the other shaders. In the program that I am…
