We live at the beginning of the second revolution in visual media. Two centuries ago, the camera and the Jacquard loom introduced machines for creating art. By automating the artist's hand, they also forced questions of how objective technique gives rise to subjective meaning and where the border lies between mechanical and human contributions. Those progenitors eventually led to digital film, computer games, and digital content creation for architecture and industrial design.

Today, accessible and pervasive computation provokes a second revolution. Augmented reality, 3D scanning, 3D printing, virtual reality, and computational photography are exploding into mainstream experience. Where previous digital media refined analog practice through evolution, these are revolutionary forms that could not exist without computation.

As the world seeks the promise of new visual forms, we find that fundamentals of earlier media remain valid and take them as our guide. This tutorial investigates the technology of emerging computational media and explores their impact on the relationship between process and aesthetics.

Administrative Catalog Information: This course is a tutorial. It may not be taken on a pass/fail basis or as a fifth course. Requires CS256: Algorithms. The course is capped at 10 and preference will be given to current or expected Computer Science majors per department policy.

Structure: You and your tutorial partner will meet with me once a week. One student will present the assigned reading and the three of us will discuss and debate it. The presentation role will alternate weekly between students, and both students will be graded on performance each week. In some cases, a short essay will also be required from each student.

One goal of the course is to practice presenting technical material carefully. I will evaluate your presentation style and clarity as well as content. Grading will be based on the geometric (not arithmetic) mean of those different elements to encourage you to develop your weakest areas over doubling down on strengths.

There are no mandatory programming exercises and no exams. I anticipate that the average final grade in the course will be 3.5. As this is the first offering, grades will be curved after ranking students to ensure a fair scaling.

Sessions: All meetings in TCL308 by default.

There is a special organizational meeting on Thursday, September 10 at 8:30pm in TCL104B to meet as an entire class, review this syllabus and answer questions about it, and arrange times for future full-group meetings.

Assignments: For each week there is typically one key reading for presentation and discussion. Supplemental readings preceeding it help to provide background if you haven't encountered the topic before. Supplemental ones following it are related works that expand the topic or provide an alternate view. You don't need to read all of the supplemental material. I predict that the top students in the course will regularly reference ideas from followup supplemental material during discussion and that everyone will at least skim the background material for many topics.

We'll use The Graphics Codex as a common textbook for supplemental readings that concisely survey well-understood areas of graphics. I recommend Computer Graphics: Principles and Practice as a comprehensive overview of the mathematics of graphics. CG:PP, the other supplemental books, and the films are on reserve in the library (plan ahead or buy your own copy: there will be a lot of demand). I recommend screening the films as a group because you'll hear each other's reactions during the screening and naturally discuss them afterwards. The games referenced are available in the Unix lab.

Expect to spend up to ten hours per week on the reading and to feel a bit overwhelmed or lost about half of the time. You may--and should--collaborate with your tutorial partner and others in the course without restriction outside of session, so long as you acknowledge their contributions in any written documents.

I list some sample questions for each topic. Although you may, you are not required to explicitly answer these questions or raise them in discussion. Instead, you should use these as guides to focus your initial reading and help determine whether you understand the articles and their impact. When you struggle with the questions, go back to more of the supplemental reading to help provide context. I expect you to go far beyond my initial questions in your full exploration and discussion.

Beware that particularly for a scientific publication, the "pitch" of the paper was tuned for the reviewers at the time of submission. It often does not stand the test of the time in the manner of its actual content. In many cases, the significance of the paper is not its primary claim, at least, in the manner it was presented.

Because tutorial groups will move at slightly different speeds and may follow up with additional readings to dive deeper into some topics, these assignments aren't tied to specific weeks. Proceed through these in order. It is the responsibility of the presenting student to ensure that the partner and professor agree a week beforehand on the topic.

Reading: Do not read a scholarly paper or book like a novel. When studying films and games, you also need to have both the experience of a "normal" audience member and to step back and analyze that experience. You must be an active participant to approach the reading material in this course. For many people (including me), it is generally hard and a bit unpleasant, although there is joy in appreciating it more deeply and discovering insights.

When working with readings other than peer-reviewed scientific publications in this course, I intend that you approach them through the lens of science. Analyze and critique them in light of the related scientific work from that week and other readings in the course. Propose methods for quantifying or automating, or enumerate the tecnical challenges in delivering the vision that they put forth. This is the core of how computational graphics research and development advance: by understanding the goals of authors of visual media and then specifying and creating technology to support them.

It is easy to criticise older works in light of newer ones and modern cultural mores. Such critism is largely a waste of time, so avoid the temptation to take cheap shots. If I assign an older work, it is so that we can learn from their methodology, as well as appreciating the evolution of visual media to predict its future. Ask how important older works innovated relative to their historical contexts, and what they teaches us about how to innovate in our own historical context. This is the most important lesson to take away from the class: how great scientists and artists work, not the specific output that they produced as a result of their time and place.

Scholarship builds on the shoulders of giants. In any scholarly work, probably 90% of the impressive work is actually something that was well known in the field beforehand, 9% is an application of an existing idea in a new way, and maybe 1% is true innovation or new insight. This is often not clear from the text, and you're expected to be familiar enough with the area to understand what is really new.

For example, reading Kajiya's "The Rendering Equation" paper, you might reasonably think that he invented the rendering equation (he didn't) or recursive ray tracing (no)--actually, he's contributing analysis and a crude form of importance sampling. In Jensen's "Global Illumination with Photon Mapping," you might think that the photon tracing and radiance estimation are his contributions. In fact, his contribution is using a k-d tree for the photon map instead of a flat array, and some particular low-precision representations of photons. Those are both really important graphics papers, but not for the reasons that they might appear to be. It is easy to watch Star Wars: A New Hope and find it innovative for effects and style...but much of that is coming from the less-known 1972 Silent Running (which was also laying the ground work for WALL-E, and was following up on Trumbull's FX work on the Kubric film 2001). The 1982 Blade Runner is revisiting many of the themes and visuals from Lang's 1927 Metropolis and 1931 M (all of which are cinematic masterworks!)

For computer science and mathematics papers, I often have to stop and write a little program to test the ideas from the text or fully grasp them. I expect that you may too. Don't look at equations or code lisings and just say, "yes, that looks about right." Ensure that you could reproduce them. Run through the execution of algorithms by hand as if you were a computer.

I usually read the title and abstract, and then jump to the results section. I try to understand how well the technique works from the figures. Then, I double back to the related work section to see how this paper relates to work I'm familiar with. I may then go to the algorithms section or introduction. Once I have a basic idea of what is going on in the paper, I return the the beginning and make a full read of the whole thing.

Expect to read some text, pause, ask yourself a question about it, and try and figure out the next step on your own. When you're reading an equation or looking at a diagram, ask yourself what each symbol means. If you're not quite sure what is going on, don't keep reading--backtrack and read that section again. Maybe out loud. Try reproducing derivations. Be prepared to skip around, refer to supplemental material or cited previous work, and re-read critical passages many, many times.

For film and media criticism, I often have to step back and summarize the author's points and then try to apply them in a new context for evaluation. All professional writers are facile, and it can be easy to let the words roll over one unquestioned. What are the key terms? What are the supports for the argument or claims for the analysis? What are examples outside the text that support it? Can I think of contradictory examples?

For visual works themselves, I find a good approach to analysis is to focus on technique. What other works is this one referencing? Can you find the same shot/mechanic/line/costume/etc. in another work? This scene makes you feel sad--why? Is it sad with the sound off? Would it still be sad if viewed from another angle? How frequent are the cuts? Where are the cameras and lights? Are all of the shots from the same take or spliced from different performances? Make a color script for the work. Make notes on the musical score and effects. Whose point of view is represented? How reliable or unbiased is that viewpoint? Are the actions depicted literal? In a game, why did you make the choices you did? How did you know the rules? What interactions are making you empathize with specific characters?

I'd like to think the following is obvious, but since this may be your first experience studying in multiple media, they may only be obvious points in hindsight. You must first engage each work as it was intended to be experienced. You can't experience a film by reading about it--you must watch it. You can't experience a game by watching someone else play it--you must play it yourself. You can't experience a VR session through a desktop port. You can't experience a sculpture by looking at a picture--you must go see it in person. Etc. If a film was intended for a theatre screen, watch it on the largest screen that you can find (e.g.: Paresky auditorium or any classroom), in a dark environment. Don't force it into a YouTube window while you're chatting on Facebook in a crowded common room.

Presenting: Each week, the presenting student must e-mail an agenda to his or her tutorial partner and me at least 48 hours before our session. This agenda may be in the form of an outline (in ASCII text, HTML, or PDF) or PPT slides (only PowerPoint is allowed). It must include the major points of the presentation, presentation aids or their descriptions, and some key questions or issues for discussion. However, if you're working closely with your partner to create the presentation, then you can send me the slides at the last minute. I'll give you more useful feedback if you send it earlier.

The presenting student will walk us through the reading in about 30 minutes. Available tools include PowerPoint on my laptop, an HDMI 1080p TV, printouts, and a blackboard with colored chalk. Plan for 15 minutes of material, which will be slowed to about 30 minutes by questions. If working with your partner to create the presentation, don't over-polish the content. Figure out a lot of it for yourselves, but also leave openings for us to explore it further in session instead of working everything out. I want to be an active part of the exploration process rather than seeing a perfect and final presentation.

Specifically, you have three good choices when you encounter terms and ideas that you don't understand in the work:

  1. Don't mention these topics (and if I ask, you can refocus the discussion on what you did want to talk about)
  2. Figure out what this topic is and explicitly present it, or at least be prepared to present it if asked
  3. Explicitly mention what you didn't understand (possibly because you didn't have time to trace down this tangent) and then open it for discussion
I prefer the last option because I want the tutorial to be about us figuring out this material together in small groups. Ideally, half of your presentation will be devoted to things you struggeled with and want to dig deeper on. However, topics have varying worthiness for investing our limited discussion time on. What you should not do is mention a topic in passing and hope that your partner and I won't notice. If you've raised an issue in a presentation, you must be prepared to resolve questions about it in some way.

If using slides, I highly recommend cutting and pasting figures, still shots, and equations from the source work. Minimize on-screen text (although you're free to insert text in Presenter Notes) and instead present those ideas orally.

Throughout the presentation, the non-presenting partner should add asides with new information, raise questions about what he or she didn't understand (or the pair didn't understand), and help respond to my questions. Near the beginning of the semester, partners often choose to work as a pair and have equal understanding of the work. But as your other obligations grow during the semester, it is reasonable for the presenting partner to take the lead and use the session to help the other partner understand the work during our session.

The conversation may naturally transition to a free-form discussion of the work and issues that it raises. If it does not, the non-presenting partner should explicitly shift us into a more free-form discussion after about 30 minutes.

  22. What are Hilbert curves, and why are they frequently used in computer graphics data structures?

  8. Is the camera a reliable observer, or are we being shown events as perceived by specific characters?
  9. What does the audience observe or know that the character doesn't? What does the character know that the audience doesn't? (Obviously, this changes over time)
  10. What are the "special effects"? When are we seeing minatures, stunt doubles, forced perspective, or other tricks that create an artificial reality different from what really occured on set?
  11. When are you aware of the camera and lights, and when does the film fade into your own reality?

  2. What is INRIA?
  3. What is "cinematography"?
  4. What is the "ray casting" algorithm, and how would it be used for camera control?
  5. What is a "semantic representation"?
  6. Write pseudocode for a Hitchcock-style camera control algorithm to be executed by a human or extremely sophisticated AI. What are the major differences between this and the methods described by Christie et al.?
  7. Shadow of the Colossus and Super Mario 64 were widely regarded in the games industry as having the best cameras of games of the era of the ones discussed in the paper. Why? Are their techniques represented in the paper?
  8. The paper is from 2008; many games have been released since then! How do each of the the following games advance the state of the art for cameras in virtual worlds?
    1. Republique
    2. Heavy Rain
    3. Uncharted 3
    4. God of War 3
    5. Bayonetta 2
    6. The Order: 1886
    7. The Last of Us
  9. Real-time 3D programs emulate some real camera effects, such as lens flare, depth of field, chromatic abberation, vignetting, and motion blur...but they currently do so imperfectly. How does this affect cinematography in real-time 3D applications
  10. Rephrase this sentence in your own words: "In practice, even partially automated three-dimensional multimedia generation requires an interpretation and synthesis framework by which both the visuospatial properties of a viewpoint can be computed (i.e. the interpretive framework) and the viewpoint controlled according to the constraints arising from the semantics of the language used (i.e. the synthesis framework)."
  11. Why do the authors claim that camera control is PSPACE-hard? Do you agree, or think it is harder or easier?
  12. What does it mean for a camera model to be "Euler-based"? Why is that name used?
  13. What is "gimbal lock"?
  14. Why is real-time camera control perhaps closer to documentary cinematography than fiction-film cinematography?
  15. Name and define some methods for shooting dialogue.
  16. What are the major camera control algorithm classes?
  17. What are the major direct control methods for cameras?
  18. What are all of the variables in equation 3? What does it signify?
  19. Almost all of the methods described abstract geometry to simple boxes, points, and spheres. Is this reasonable? Is it a major source of error?
  20. Are graphics researchers working on the right problems in cinematography? Are there open problems, or do current approaches cover the space pretty well?
  21. Direct character control is the major motivation for avoiding cuts and certain kinds of camera movements in games. However, recent games are increasingly moving to higher level control of characters--this lends itself to more interesting interactions as well. What are current or hypothetical interaction paradigms that admit more interesting cinematography?
  22. How does the cinematography in the latest video games compare to classic Hollywood cinema? To today's cinema?
  23. How would you incorporate principles from film cinematography into real-time applications?
  24. How does virtual reality change the goal of real-time cinematography?
  25. The paper poses an interesting idea in passing: game cameras are like documentary ones, where they report the action of the game somewhat objectively and with minimal manipulation of the scene. This gives some insight into the constraints on game cameras and where we might look for specific techniques. But it also prompts the question of how objective non-fiction film really is. What are the major differences and "rules" for editorial control in:
    1. Cinema Verite
    2. Direct Cinema
    3. Visual Journalism
    4. Documentary
    What does it mean for a visual work to accurately depict its subject? Does that preclude editorial control and manipulation? Can that in fact be achieved without editorial control and manipulation?
  26. As a followup to the previous question, perform some cursory research (Wikipedia and IMDB are fine in this case) on the following landmark works:
    1. Nanook of the North (1922)
    2. Man with a Movie Camera (1929)
    3. An American Family (1973)
    4. The Thin Blue Line (1988)

    6. The Bridge (2006)
    7. The Act of Killing (2012)

    Questions and Exercises:
    1. What are the goals of stylized rendering? There are many; there are many different viewpoints in the field about goals and methodology.
    2. Prior to this paper, how was line-drawing rendering researched in computer graphics?
    3. What is the experiment? Focus on the critical aspects of its design, not just generality. Why are the choices that they made important in the design?
    4. How was the gathered data reconciled across subjects, since each person will draw with a different scale, orientation, and internal proportion?
    5. What are sources of error in this experiment?
    6. Why is this experiment significant for computer graphics?
    7. Try the experiment with a small group. Draw a few of the shapes in isolation.
    8. Define all of the major curves recognized by computer graphics (e.g., contour) both mathematically and intuitively (you may need to look at prior art to find good definitions).
    9. Identify in your own drawings which curves you used, and where and why.
    10. Artists are seeking to convey different things in different styles. Are edges conveying shape or value in your drawing? For what applications would different choices be important? (Consider all of the places that line drawings appear)
    11. This experiment was a good way of objectively extracting the expertise of artists (although many of the participants don't appear to be very good artists...) However, the scientists then make their own naive subjective statements about the data towards the end of the paper. How could that be improved?
    12. I asked professional artists about some of the images. The best answer I received to "How would you draw this?" was..."I wouldn't. I'd draw it from another viewpoint. This is an ambiguous composition.". This answer has deep implications for how we should pursue stylized rendering, some of which are (computationally) unfortunate. Unpack the artist's statement, my claim, and the implications.
    13. Human artists learn by a combination of theory and reinforcement learning. What are the corresponding algorithms? How might that be applied in computer graphics?

    Questions and Exercises:

    This topic is challenging, inherently, and by design. I want you to still bring a technical perspective and scientifically-grounded arguments, but you'll use those techniques to question our goals themselves.

    The overall point is: while computer scientists are trying to solve the problems of rendering 19th and early 20th century paintings (see the expressive graphics topics from this course), creating special effects for films that are anchored the 1970's, and working to build the virtual reality vision articulated in the 1990s, here is what leading artists are doing in mainstream visual media today.

    Moreover, the examples chosen are self-reflective, addressing the current art of games and film in a way that is simultaneously optimistic and highly critical. This prompts a number of issues:

    1. are we even solving the right technical problems? Maybe nobody wants a human-created oil painting any more, let alone one from a computer.
    2. Are there technical problems in current forms that we should be solving?
    3. What do new works tell us about the relative importance of technique vs. technology?
    4. Are new media technologies such as VR going to advance art, or is technology not where the serious problems are any more? Don't dismiss technology out of hand--the automated loom, new paints, the printing press, the camera, sound recording, and the computer undeniably advanced visual media.
    5. How are the analogous criticisms of film and games implicit in these works likely to manifest in new media, such as 3D printing, VR, and AR experiences? Can we minimize those in advance through careful design?

    Optional two-week programming assignment:

    Implement a 2D point mass + massless spring animation system in the style of (the now-defunct) Sodaplay and evolve creatures for a task. Sample tasks are: run fastest, jump highest, cover the most area (pick up rings). The Sodaplay system is nice because it requires only 2D point and spring physics plus collision with planes; that is a lot less complex than rigid body, arbitrary collision, and 3D physics, which lets you focus on the evolution aspect. The only parameters in this system are: topology, spring constant, spring rest length, mass, motorized spring period, motorized spring phase.

    Consider what kind of locomotion you want: friction against the ground plane and gravity lead to walking and jumping, friction against the environment and weak gravity leads to swimming or flying, etc.

    You might consider the option of some creatures that can have springs to the ground, making them plants. It is easy to extend to creating an ecosystem under this model by either parallel evolution of different classes of creatures with large populations feeding on one another and competing for reasources.

    I hypothesize that one reason many evolved creatures look unnatural is that they lack any model of sensors and delicate internal organs. One way to extend this project is with a notion of sensing located at a specific, vulnerable point, as well as some abstract organ cavity. Creatures would ideally evolve to protect their sensitive bits and favor motions that protect and hold high their sensors.

    If you're excited about making your creatures look good as well as animation, you might try fixing the topology and then stretching a sprite over them using As-Rigid-As-Possible Mesh Animation. In this way, you could easily make something that looks like an animated cartoon insect or dinosaur.
