Geometrical Modelling in Graphics (Course Materials)

Lecture Monday 8:10 M-XII Exercise Tuesday 13:10 M-XII

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. Programming, modelling projects and oral exam.

What you Need to Pass

• Attend lessons. One missed +0 points. 2 missed 0 points, 3 and more is Fx.
• Programming, modelling project with production and exercise (mandatory, 50 points). Submission after deadline -50%.
• All programming is checked with deadlines during the exercises.
• Pass oral/written exam: (+50 points) If you feel you are better, convince me !
• Summary
• Attendance = 0 or -100 (Fx)
• Projects = +50..0
• Oral/written exam = +50..0
A = 92-100
B = 84-91
C = 76-83
D = 68-75
E = 60-67
Fx = 0-59

Oral Examination

To the oral examination all the above requirements must be SATISFACTORILY completed. Random lecture topic will be selected and presented by a student after written preparation.
