Students will be provided a kit to build their own head-mounted display, including an LCD, an HDMI driver board, an inertial measurement unit (IMU), lenses, an enclosure, and all cabling. Kits must be returned at the end of the course. All software will be developed through the homework assignments. Component details are listed below. The headset kit will be updated for Winter 2025, replacing the VR enclosure with an HRBOX2 AR headset.

Schedule

Assignments

Students will complete five homeworks and a final project. Each homework is accompanied by a lab (a tutorial video). Labs must be completed before starting the homeworks. We encourage formatting written portions of homework solutions using the CSE 493V LaTeX template. Students must submit a one-page final project proposal and a final report. Final reports may take the form of a website or a conference manuscript.

Grading and Collaboration

The grading breakdown is as follows: homeworks (70%) and final project (30%).

Assignments are due by midnight on the due date. Each student is granted a pool of four late days. Up to two late days can be used on any given homework, with instructor permission required for longer extensions. Beyond permitted delays, late assignments are marked down at a rate of 25% per day. That is, if a student fails to turn in an assignment on time it is worth 75% for the first 24 hours after the deadline, 50% for the next 24 hours, 25% for the next 24 hours, and then it is worth nothing after that. Exceptions will only be given with prior instructor approval.

While the headset development kits will be shared, students are expected to individually write their homework solutions. Students may collaborate to discuss concepts for the homeworks, but are expected to be able to explain their solutions for the purposes of grading by the instructor and TAs. Final project groups can be as large as three students, subject to instructor approval.

Textbooks and Resources

Lectures are supplemented by course notes, journal articles, and textbook chapters. The following textbooks will be used for CSE 493V, which are freely available to University of Washington students via the links below.

• Marschner and Shirley. Fundamentals of Computer Graphics. 4th Edition. CRC Press, 2015.
• LaValle. Virtual Reality. Cambridge University Press, 2016.

All software will be developed using JavaScript, WebGL, and GLSL. Students should review the following tutorials and online resources to prepare for the labs, homeworks, and final projects.

• w3schools.com: JavaScript Tutorial
• WebGL using three.js: Slides, Video, Documentation, and Source
• kronos.org: WebGL 1.0 API Quick Reference Card

Office Hours and Contacts

We encourage students to post their questions to Ed Discussion. The teaching staff can also be contacted directly at . The instructor and TAs will hold weekly office hours at the following times.

• Douglas Lanman (Wednesdays, 5:50pm to 6:30pm, CSE2 G10)
• Evan Zhao (Mondays, 2:00pm to 3:00pm, CSE2 153; Wednesdays, 2:30pm to 3:30pm, CSE2 153)
• Shaan Chattrath (Tuesdays and Thursdays, 4:30pm to 5:30pm, Allen Center 218)
