I am pleased to announce the release of my new book
Open Shading Language for Blender, a practical primer.
it is a hands-on introduction that starts with simple example shaders that implement all sorts of patterns, continues with shaders for things like leopard spots and citrus fruit skin and ends with quite elaborate shaders that for example use external texture files, use information stored in xml files or mimic 3D transparent objects on a 2D plane.
It is a book about programming of course but you don’t need much programming experience to follow along. Each piece of code is explained in detail and example images are provided so that you know what to expect and I show relevant node setups. Of course all shaders are available for download, including .blend files to try them.
So, if you would like to start out with OSL you might visit the book site in my signature or you might download a sample first from my sample page:
