HOME WORK

  • Assignment of homework: [pdf]
  • Deadline is monday lesson 7.11.2016
  • 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)

PROJECT 01

  • Deadline is 13.11.2016 23:59

Select and create 4 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).

Send the archive to adam.riecicky@fmph.uniba.sk

PROJECT 02+03

  • Deadline is exercise 6.12.2016

Create a realistic rendered image of a complex scene using at least 2 of your models and the others you've downloaded, applying textures and materials to these models by yourself. Scene examples: beach, snowy mountain town, a room, city street, a forest, desert, etc...

Compulsory techniques: texturing (min 3 models), bump mapping, displacement mapping, specular map, multiple lights,

For submitting follow the rules from Project 01 assignment. Add the best rendered image of your scene to the submitted archive.
