Shading Fearlessly now in print!

Visit lulu.com for more information and ordering:


This is the latest addition to the 3DTangle Shading collection: a full color printed version of the book for those of you who want to have the book in your hands (and not just on the screen).

I had a lot of requests for a printed version, so here it is! I used a service that I have used for many years, lulu.com, and the results did not disappoint, I'm SUPER happy with the quality of this full color printed book. Not only the print is sharp and beautiful, the colors accurate, but the paper is also really thick and smooth.

You will have no problem seeing the details in this gorgeous large format book, you can see every single detail as I intended it to be.

For now it is is ONLY AVAILABLE through lulu.com:
