Slides: [ slides ] [ slides with annotations ] Exercises: Tutorial 4 (Perspective projection and hidden surface elimination) [ 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). For octrees, please refer to the lecture notes since they are not covered in the textbook.
