This post takes a look at adding a physically based sky model, in addition to adding textured material support. These features, combined, result in much nicer images than the basic renderer, without appreciably slowing down the renderer. Unlike the previous post, where the sky color was an almost flat shade of blue, we now have an actual light source in the scene, the sun. Notice the light reflected off the gold orb onto the checkerboard pattern in the image below. As you rotate the sun around the orb, you can watch the reflection move in real-time. Nothing was changed in the way the rays bounce off the spheres, the spheres are simple reflecting a much higher quality sky. There are many sky models to choose from, all with distinct goals and use-cases in mind. The sky model I chose was the Hosek-Wilkie model.

Some of the equations and code EG: ray refraction, Shlick's approximation were quickly glossed over, and required additional work from the reader to understand.

Using these technologies vastly simplifies the ability to write applications using ray tracing.

I'll tell you this - I've never written anything else that comes near this ratio of satisfaction per line of code. The generated PPM file can be viewed directly as a regular computer image, if your operating system supports this image type. Great into to ray tracing Concisely introduces the core concepts of ray tracing. Peter Shirley. Aug 11, This informal book takes you through most of the author's university course on ray tracing.
