Exercises

guide: Adam Riečický

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.

Evaluation
80p - Practical Modelling Project ( 2 x 40p )
20p - Technique Description (compulsory)

Semester Outline

For help see Blender Shortcuts and Controls

27.9. Blender Basics

Warm up and get familiar with the interface.

Please fill out Blender experience questionare.

4.10. Mesh Modelling Fundamentals

Try out mesh edit mode and editing tools.

Practical home assignment
Pick two or more furniture objects from IKEA LIATORP living room series.
Model them using techniques learned on exercise.
Send .blend file at adam.riecicky@fmph.uniba.sk until 23:59 7.10.2018 with finished objects to earn 2 bonus points.

11.10. HDR and Environment Mapping

Understanding colors and radiance
Representing values in HDR file format
Computing green component from input radiance (using Simpsons 1/3 rule)
You can search for Simpsons 1/3 rule in a book Numeric Mathematics on page 104 (123 in pdf)
Practices in Blender
Download HDR environment maps from the web
Creation of elemental materials and applying environment maps
A problem of HDR environment maps and how to fix them?
Introduction to node editor

25.10. Blobby objects (Metaballs)

What are blobby objects, how are they used and what are they good for

Project

The project is focused on practicing techniques of modeling and rendering learned on exercises. It is split into two stages evaluated separately throughout the semester.

Stage 1

Deadline on Sunday 18.11.2016 at 23:59

Assignment
Choose 1 object from each modeling category:
Simple Polygonal: apple, lamp, book, chair, etc.
Curve: light bulb, vine glass, candle holder, corkscrew, etc.
CSG: mug, ashtray, etc.
Blobby: candle, etc.
Find reference images for objects and model them using learned techniques.
Make a final render of each model.
Evaluation
Use correct modeling techniques for each model category (10p)
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 modeled detail (5p)
Editing friendliness - not applied modifiers, low polygon count (5p)
HDR environment map with correct values for the sun (10p)
Basic material on each model and shadow receiver plane for final renders (5p)
Aesthetic of created models - proportions, realism, etc. (5p)
Submission
Before modeling create folder named "mrt_p1_[your name]" and place all files inside that folder.
Each model should be located on a separate layer
Folder should contain ONLY ONE blend file, object reference images, and HDR environment map
Pack folder to archive (zip/7z/rar) and send to adam.riecicky@fmph.uniba.sk with subject "MRT Project 1"
