SkSL

Skylang, commonly referred to as SkSL, is a programming language developed by Apple Inc. for compiling shaders for graphics processing units (GPUs). It is used in various Apple products, including Mac computers and iOS devices.

SkSL is designed to be efficient and easy to use, allowing developers to write shaders that can be compiled directly to machine code for the GPU. This results in faster rendering and improved graphics performance. SkSL is similar to other shading languages such as GLSL and HLSL, but it is specifically tailored to work with Apple's Metal API, a low-level graphics API.

One of the key features of SkSL is its high-level syntax, which makes it easier for developers to write complex shaders. This includes features such as type inference, automatic differentiation, and improved error handling. SkSL also supports programmable pipeline stages, allowing for more expressive and efficient shaders.

SkSL is used in a variety of applications, including games, computer-aided design (CAD) software, and scientific visualization tools. Developers can write SkSL shaders using a variety of tools, including the Xcode integrated development environment and the Metal Performance Shaders (MPS) library.

SkSL has evolved over time, with new features and improvements added in each subsequent version. The language is actively maintained by Apple and has a dedicated community of developers who contribute to its growth and development. Overall, SkSL has become a widely-used and adaptable shading language that has enabled developers to create high-performance graphics on Apple devices.
