Grading

No make-up exams will be given for missed tests. All the assignments should be turn in by the designated due date. To pass this course all the course requirements must be SATISFACTORILY completed > 30% of each problem set.

What you Need to Pass

  • Attend lessons. One missed +0 points. 2 missed 0 points, 3 missed 0 points, 4 and more is Fx.
  • Project and exercise (mandatory, 50 points).
  • Solve all homework problems (mandatory each one >=30%, 20 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 !

Exercises

guide: Adam Riečický

Wednesdays at 8:10 in F1-248

Intro slides

The exercises will be focused on the practical approach of modeling and rendering using Blender. The evaluation consists of two projects covering exercised techniques.

Evaluation
50 pts - Project Stage 1: Modeling
50 pts - Project Stage 2: Rendering

Notes

24.9. Blender Basics

Please fill out Blender experience questionare.

Warm-up and get familiar with the interface.

30.9. Mesh Modelling Fundamentals

Trying out mesh edit mode and editing tools.

Practical home assignment [2 bonus points]
Pick two furniture objects from IKEA LIATORP living room series.
Model them using techniques learned on exercise.
Send .blend file with finished objects and reference images at adam.riecicky@fmph.uniba.sk.
Deadline: Tuesday 6.10. 23:59
