Slang Examples

This directory contains small example programs showing how to use the Slang language, compiler, and API.

• The hello-world example shows a minimal example of using Slang shader code more or less like HLSL.

• The shader-object example shows how Slang's support for interface types can be used to implement shader specialization with simpler logic than preprocessor-based techniques.

• The gpu-printing example shows how Slang's support for string literals can be used to implement a cross-API "GPU printf" solution

Most of the examples presented here use a software layer called gfx (exposed via slang-gfx.h) to abstract over the differences between various target APIs/platforms (D3D11, D3D12, OpenGL, Vulkan, CUDA, and CPU). Using gfx is not a requirement for using Slang, but it provides a concrete example of how tight integration of Slang's features into a GPU abstraction layer can provide for a clean and usable application programming model.
