Exercises
guide: Adam Riečický
Wednesdays at 8:10 in F1-248
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
7.10. Mesh Smoothing and Modifiers
- Understanding Blender modifiers. Subdivision surface modifier vs subdivision tool, mirror modifier, array modifier.

Project
The project is focused on practicing techniques of modelling and rendering learned on exercises. It is split into two stages evaluated separately throughout the semester.
Note: Accomplishing bonus tasks grant you an additional points, but cannot get you over the maximum of 100p from exercises.
Stage 1
Deadline on Sunday 15.11.2020 at 23:59
Goal of this project stage is to create models for interior "room" scene.
- Assignment
- Find reference images for objects and model them using learned techniques.
- Create 2 objects from each modelling category:
- Simple Polygonal: apple, lamp, book, chair, etc.
- Curve: light bulb, vine glass, candle holder, corkscrew, etc.
- Create 1 object from each modelling category:
- CSG: mug, ashtray, bowl, etc.
- Blobby: candle, toy (teddy bear, dino, ...), etc.
- Evaluation
- Use correct modelling techniques for each model category (20p)
- Simple Polygonal: extrusion, inset, loop cutting...
- Curve: curves, screw modifier...
- CSG: boolean modifier, parenting, object hiding...
- Blobby: metaballs, negative influence...
- Complexity of selected reference and modelled detail (15p)
- Editing friendliness - not applied modifiers, low polygon count (10p)
- Aesthetic of created models - proportions, realism, etc. (5p)
- Submission
- Before modelling create folder named "mrt_p1_[your name]" and place all files inside that folder.
- Each model should be located in a separate collection
- Folder should contain ONLY ONE blend file and object reference images
- Pack folder to archive (zip/7z/rar) and send to adam.riecicky@fmph.uniba.sk with subject "MRT Project 1"
