    • Homework = +20..7 or +6..0 (Fx)
    • Project = +50..0
    • Mid term = +10..0
    • Final term = +20..0
    • Oral/written exam = +20..0
  • Grades
    • A = 92-100
    • B = 84-91
    • C = 76-83
    • D = 68-75

Thursday 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.
