Verzia zo dňa a času 15:48, 18. september 2014

This lecture ...

Will focus on simulating natural phenomena
Will show you what are current topics
Will improve your skills in
- Newtonian physics
- Computational geometry
- Algorithms and data structures
Hopefully will not be boring

Written exam (optional): deadline 19.1.2014, 8:00, classroom A
- Instead of (optional) oral exam, you can get (-20 ... +20) points due to a written exam.
- It will be similar to final term, but less complicated.
Coders (Cxx): deadline 26.1.2015
- Create a web page where you write your progress, upload source code, executable, images description of your project and short manual.
- Send link to finished application (zipped source + executable.)
- If you send it earlier you can get feedback how to improve your application
Animators (Axx): deadline 26.1.2015
- Create a web page where you write your progress, upload animation, source of animation, images description of your project and all physical effects to be evaluated.
- Upload your animation video on youtube (or some alternative online service)
- Send link to your webpage
- If you send it earlier you can get feedback how to improve your animation

Attend lessons. All lessons attended is +10 points. One missed +0 points. 2 missed 0 points, 3 missed 0 points, 4 and more is Fx.
Show your project (mandatory, 60 points) See later.
Solve all homework problems (mandatory each one >=30%, 30 points)
Pass final term (mandatory, 10 points) You will need to solve several problems discussed during lessons.
Pass oral/written exam: (optional, +/-20 points) If you feel you are better, convince me ! You can get +20 points or loose -20 points.
Summary
- Attendance = +10..0 or -100 (Fx)
- Homework = +30..10 or +10..0 (Fx)
- Project = +60..0
- Final term = +10..0 (> 30%)
- Oral/written exam = +20..-20

Take 2 friends and Team up
Role1: The Coder
- Choose a given animation algorithm
- Code up hot demo app and show it
Role2: The Artist
- Choose some authoring tool and create hot physically based demo reel
