• Current scientific visualization techniques: (1) complex images; (2) difficult to interpret; (3) no expressiveness of illustrations. • Illustrative Visualization (IVIS) enhance the depiction of scientific data based on principles founded in traditional illustration. IVIS = Sci. Vis + NPR

• Non-Photorealistic Rendering (NPR): omit extraneous detail, focus attention on relevant features, clarify, simplify, disambiguate shape, and show hidden parts.

Expectations • Interested & Motivated • Explore uncharted territory (i. e. , do research) • Organized around topics • Presentations + Discussions = Learning! – Understand the idea yourself – Present the basic idea as clearly as possible – Ask the dumb questions that will help us all understand. – Questions are much more important than answers!

IVIS Week • Monday, Tuesday, Thursday – I’ll introduce the topic + research area – Key techniques, algorithms (1976 – present) – Lecture/paper presentation & discussions – Students present papers – Discussions

Participation Participating in reading and discussions is extremely important in this course! 1. Read class material, understand basic issues • As an indicator of this, you must turn in Paper Reviews & Questions 2. Attend class 3. Active class participation

Participation Paper Reviews • Read the paper and answer the questions that are applicable. • Keep it short but try to give thoughtful answers. • Very important: turn in two good questions about each paper discussed in class. – The questions should be 1 -2 sentences long, and should demonstrate you’ve made a good attempt at the material. • Reviews are due on the day the class begins discussion of a given group of papers. • Use the following format for each paper: review-form. doc

Presentations • Each student will research 3 relevant papers (from the list of papers in the course schedule) • Make a Powerpoint presentation, and present the results to the class • These presentations will be posted afterwards onto the class website for reference by present and future students.

Presentations • 15 minutes each (allowing 10 minutes for questions and interaction) • Should center around the main idea, and the novelty of it • Emphasis is also on the future work, and what was missed.

Presentations • For each paper: – Problem: what problem are the techniques designed to address? – Basic idea: at a high level, what is the approach taken by the solution(s)? • How of the technique: at a high level, describe the algorithms, data structures, key equations – Critique: what are the shortcomings and strengths of the approach?

Presentations • Think about what could make interesting discussion points • Often, questions from the review form can work well for this. • Some questions may be controversial and so are good for discussions. – – • Is the paper important? Are the contributions significant? Does it have real applications? Did people like it (or hate it)? Opinions will often vary widely.

Project • Apply what you learn • Document your project in a high quality paper and presentation. • All projects will be presented at a public colloquium. • A significant investment (several weeks) of your own time • Project topics will be chosen in consultation with the instructor.

• Expectation quality work that the students would not be embarrassed to submit to a workshop. • There exists the potential for projects in this course to turn into longer-term research efforts. • Choose to work on something that interests you deeply. • You must describe what value you added in your project work.

Project Web Page • Build a project web page (login/passwordprotected). • It does not have to be fancy. • Include links, texts, images, etc. to all material related to this course -- your paper presentations, reviews, results, reports, etc.

Project Deliverables • • Proposal (written) Progress Reports Final Presentation Final Project Report , System and Results • If possible, Conference Submission
