# Exercises

Monday 16:30 I-H6

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

### Evaluation

20p - Attendance ( 10x2p )

45p - 3D Modelling Project ( 3x15p )

35p - Presentation (compulsory)

19.9.2016

### EXCERCISE01 "Blender Basics"

26.9.2016

• Assigning presentation topics
• Introduction to Blender, workspace, 3D view manipulation, objects and their transformations,
• For help see Basic shortcuts and controls

### EXCERCISE02 "HDR and Mesh Modelling Fundamentals"

4.10.2016

• Find Simpsons 1/3 rule in a book at page 104
• Mesh edit mode, mesh manipulation

### EXCERCISE03 "Mesh Smoothing and Modifiers"

11.10.2016

• Smooth/Flat shading vs mesh subdivision
• Mirror and Subdivision surface modifiers

### EXCERCISE04 "F-Rep, CSG and Curve modelling"

25.10.2016

• Examples of F-rep http://hyperfun.org/FRep/
• homework help: RGB to HSL color space conversion
• read more about color spaces in book (e.g. Moderní počítačová grafika)
• use RapidTables website for online conversion and formulas (detailed calculation)
• Blobby objects and CSG in Blender
• Editing curves in blender, screw modifier

Select and create 3 models using the techniques we’ve learned.

Models: light bulb, vine glass, mug, bottle, candle holder, table, chair, corkscrew, lamp, screw, book

Compulsory techniques: extrusion, loop cutting, curves, boolean modifier

Tips:

• Find reference photos and use them as a template
• Use subdivision surface and smooth shading to produce more realistic results.

Mesh complexity and realistic looks will be rated. Screenshots of modelling process are required.

Use Screenpresso to capture your progress regularly (every change). Pack unmodified screenshots and .blend file with all finished models, each on separate layer, into an archive (zip/7z/rar).
