Projects guidelines and deliverables § § § Several small projects (some individual, some in small teams) Ethics – It is OK to look at previous solutions (posted, published, or provided for class) – Not OK to copy from other students or teams – Cite clearly all sources of inspiration for your code and your write-up – Strive to improve them: produce an original, compact and elegant solution – Demonstrate ability to finish a small project Working in teams – Work together (same time and space) on all aspects (do not split the job) – Learn from each other and learn how to negotiate and collaborate – Make sure that you each contribute much more than your share Deliverable code – Processing (or other) applet linked from your Personal Project Page (PPP) – Short and simple source code (points for elegance and conciseness) – Comments (original, clear, useful) Deliverable report – Short, concise, formal (title, authors, date, class, problem statement, refs…) – Demonstrate in-depth understanding of a topic – Explain what you have implemented, how, and why – Explain what does not work and why (suggest possible fixes) – Submit as web page with text, images, videos Jarek Rossignac http: //www. gvu. gatech. edu/~jarek MAGIC Lab Georgia Tech, IIC 9
Web site for the course http: //www. gvu. gatech. edu/~jarek/3451 – – Schedule Projects, solutions Test dates List of topics (what you need to know) http: //www. gvu. gatech. edu/~jarek/graphics – – Slides Reading Links Resources Jarek Rossignac http: //www. gvu. gatech. edu/~jarek MAGIC Lab Georgia Tech, IIC 10
Strategy for success § Attend all classes and pay close attention § Take detailed and comprehensive notes of what I and other students write, draw, or say § Work on these notes, clean them up, mark what needs clarifications, bring them when you meet me at my office hours § Make sure that you understand everything ASAP! – – – Carefully read notes and all material provided. Search additional information in books or on the web. Do all proposed exercises Ask questions in class or at the beginning of the next class. Work in small study groups and explain the stuff to others. Come and talk to the TA or to me during office hours. § Make sure that I know: you, what you know, that you care Jarek Rossignac http: //www. gvu. gatech. edu/~jarek MAGIC Lab Georgia Tech, IIC 11
Expected amount of work per week § Study your notes, handouts and additional material: 3 – Right after class – Preferably in teams – Prepare cheat sheets with important results • Allowed to use 1 page on the midtem and 2 on the final § Do practice exercises: 2 – Try doing them individually – Then compare/discuss solutions with team members § Work on projects: 3+ – – Start right away and work hard at the beginning Ask me for clarification in class Ask TA for help For team projects, work together on all aspects Jarek Rossignac http: //www. gvu. gatech. edu/~jarek MAGIC Lab Georgia Tech, IIC 12
