Mostly this is just to bump the GitHub runner, which didn't appear to pick up the last change to update the GitHub pages.

<h1 id='books'>Getting the Books</h1>
|
||
|
||
<p>The <cite>Ray Tracing in One Weekend</cite> series of books are available to the public for free online. They are
|
||
released under <a href="https://github.com/RayTracing/raytracing.github.io/blob/release/COPYING.txt">the CC0
|
||
license</a>. This means that they are as close to public domain as we can get. (While that also frees you from the
|
||
requirement of providing attribution, it would help the overall project if you could point back to this web site as a
|
||
service to other users.)
|
||
|
||
<p>Hit any of the book cover images above to begin reading. These books are formatted for printing directly from your
|
||
browser, where you can also (on most browsers) save them as PDF.

<h1 id='overview'>Overview</h1>
|
||
|
||
<p>I’ve taught many graphics classes over the years. Often I do them in ray tracing, because you are forced to write
|
||
all the code but you can still get cool images with no API. I decided to adapt my course notes into a how-to, to get
|
||
you to a cool program as quickly as possible. It will not be a full-featured ray tracer, but it does have the indirect
|
||
lighting which has made ray tracing a staple in movies. Follow these steps, and the architecture of the ray tracer you
|
||
produce will be good for extending to a more extensive ray tracer if you get excited and want to pursue that.
|
||
|
||
<p>When somebody says “ray tracing” it could mean many things. What I am going to describe is technically a path
|
||
tracer, and a fairly general one. While the code will be pretty simple (let the computer do the work!) I think you’ll
|
||
be very happy with the images you can make.
|
||
|
||
<p>In <cite>Ray Tracing in One Weekend</cite>, you will build a simple brute-force path tracer. Continuing with
|
||
<cite>Ray Tracing: The Next Week</cite>, you will add textures, volumes (like fog), rectangles, instances, lights, and
|
||
support for lots of objects using a bounding volume hierarchy (BVH). Finally, with <cite>Ray Tracing: The Rest Of Your
|
||
Life</cite>, we'll dive into the math of creating a very serious ray tracer.
|
||
|
||
<p>When you are done, you should be ready to start messing with the many serious commercial ray tracers underlying the
|
||
movie and product-design industries.
