### 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 !
- Summary
- Attendance = 0 or -100 (Fx)
- 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
- E = 60-67

# Exercises

guide: Adam Riečický

Tuesday 11:30 F1-248

The exercises will be focused on practical approach of modelling and rendering using Blender. Evaluation consists of two individual projects covering exercised topics. Also, a short presentation from assigned topic will be required from each student.

### Evaluation

20p - Attendance ( 10x2p )

50p - 3D Modelling Project ( 2x25p )

30p - Presentation (compulsory)

### PROJECT 01

**Deadline on Sunday 12.11.2016 at 23:59**

*Select and create 4 models form reference images using the techniques we’ve learned.*

- Possible models
- light bulb, vine glass, tree, mug, bottle, candle holder, table, chair, corkscrew, lamp, screw, book or other after consultation.

- Evaluation
- Use all of techniques (on any model): extrusion, loop cutting, curves, boolean modifier/
- Complexity of selected reference and realistic looks of result will be rated.
- Mesh should have as lowest number of base faces as possible.
- Screenshots of modelling process are required.

- Submission
- Use Snipping Tool or Screenpresso to capture your progress regularly (every mayor change).
- Pack (zip/7z/rar) unmodified screenshots, reference photos and
**.blend**file with all finished models, each on separate layer. - Send the archive to
*adam.riecicky@fmph.uniba.sk*.

### PROJECT 02

**Deadline on Sunday 12.12.2016 at 23:59**

*Create a realistically rendered image of a complex scene using at least 2 of your models (the others can be downloaded). Apply textures and materials to all of these models by yourself. Scene examples: beach, snowy mountain town, a room, city street, a forest, desert, etc...*

- Evaluation
- Create uv coordinates and textures for at least 3 models.
- Use
**Blender Cycles**renderer and use emission material instead light objects. - Use at least one of each: bump map, displacement map, specular map.
- Create one representative rendered image of you scene.

- Submission
- Follow the rules from Project 01 assignment (do not forget to add rendered image).

### EXCERCISE MATERIALS
