Raytracing in C++

Does anybody have any source of information about high quality raytracing in C/C++ ? I'm quite an expert at C++, so I'm especially interested in learning the basic structures and algorithms used in this process, and all the math that's behind. You can send your messages to lpireyn@hotmail.com.
