OSLShaderWriting

This repository contains the Siggraph 2023 Shader Writing in Open Shading Language course material. It is an updated version of the Siggraph 2022 OSL Shaders for RenderMan course and its repository. Open Shading Language is a project of the Academy Software Foundation.

Specifically, this repository contains the osl source code for all shaders and the make and python3 based build system desribed in the course, with some enhancements from the Layered Shading (LaSh) repository.

While the build system's Makefile and osl shaders are configured to use RenderMan 25, they will be easily altered to operate in whatever rendering system and application environment you use.

Documentation is in the doc directory.

Please feel free to use the Discussions Tab. I'd love you hear what you think, or to discuss any issues or thoughts you may have about the course or this repository and its contents.
