CS 348C Final Project Professor: Doug James Due date: Wed Feb 20, 2019 In this final project you will research and implement a topic on physically based animation (or closely related area). Groups: Work on your own, or in a group of two people. Effort: The project should involve effort comparable to earlier assignments, but not more. Try to pick something concise and simple, and do it well.

This final project has the following components:

1. Project proposal (PDF format) [Target: Wed Feb 20, 2019 (submit via Canvas)]:  To help you better define your project, and for me to give feedback, you must submit a short project proposal via Canvas.  The proposal should be in the form of a 1-2 page document, e.g., LaTeX'd in SIGGRAPH format, and include the following basic information:
• Abstract and introduction
• Related work and references
• Technical description of material (clarify the scope of what you will consider)
  
• What you propose to do, and expect to achieve
  
• What you would like to do (time permitting), but are not sure if you will complete.
• References (properly formatted, e.g., using BibTeX)
  
2. Project submission [DATE: By Wed Mar 20]: In addition to submitting your software implementation and video animation results, please also submit a brief project report (PDF document). Your report should document your results/animations, and findings.
   

Project Suggestions:  Here are a number of ideas for possible projects:

• Implement an idea from a research paper, e.g., ACM SIGGRAPH, or Symposium on Computer Animation (SCA). Many simulation related ideas are listed below.
• Construct a short animation using Houdini on a topic of your choosing. Your proposal should sketch out the animation goal and specific technical challenges that you will address. Be as specific as possible to think through process.
