CISC440 --- Final Review

Prepare for the CISC440 final exam on May 24 from 7:00 PM to 9:00 PM in KRB205. Bring a double-sided A4 note. The exam will focus heavily on materials covered after the midterm (over 80%). Expect 4 questions: the first two worth 20 points each and the last two 30 points each. Key topics include ray tracing, BSP trees, texture mapping techniques, GPU programming concepts, and various shading methods. Additionally, 30% of the exam will involve mathematical deduction and analysis. Review carefully!

  1. CISC440 --- Final Review ---Miao Tang

  2. Time, location, notes • Monday May 24 • 7:00PM-9:00PM KRB205 • You can bring a A4 size note with you, both sides.

  3. Any difference between midterm and final? • Much more emphasized on the materials covered after midterm (>80%) • 4 questions in total: • 20 pts for the each of first 2 questions • 30 pts for the each of the last 2 questions

  4. Ray Tracing • You need to know the whole process • No implementation code questions • But details about every step • Intersection? • Shadow? • Complexity? • Order of operations?

  5. BSP Tree • What is the BSP tree? • What is it used for? • How to split? (draw it, number it) • How to build the tree? • Traversal after the tree is built?

  6. Texture mapping • What are the usual techniques? • Why we need them? • Compare between them. • Topics: • Linear interpolation(problem and solution) • Minification • Magnification • Mimaps • Summed area table • Environment map

  7. GPU programming • Basic concepts (pipeline, 4 types of qualifiers) • Fragment shader vs. Vertex shader • Small

  8. Shading • Flat vs. Gouraud vs. Phong • I am looking for details: • Normal? Color? Vertex? Interpolation? • Compare them • Big formular: • Clear about every coefficient • What if I change some of the coefficents

  9. Combining question • GPU programming on some technique(like texture mapping, shading) • Texture mapping within ray tracing • BSP tree applications

  10. Only for Grads • Including all the topics for undergrads • Plus: • About 30% of the questions are mathematical deduction • Mathematical analysis on given picture or effects • Environment mapping
