Slides: [ slides ] [ slides with annotations ] Exercises: Tutorial 7, problems 1-6 (Ray tracing) [ exercises ] Recommended reading: This lecture basically completes some "loose ends" about Ray Tracing that haven't been covered in the lecture so far, in particular: Ray/triangle intersection (book, section 2.11 and 10.3.2), refraction (book, section 10.7), instancing (book, section 10.8), constructive solid geometry (book, section 10.10), faster ray tracing (book, section 10.9).
