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.

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 18.11.2018 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, bowl, etc.
Blobby: candle, toy (teddy bear, dino, ...), 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 (15p)
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 (10p)
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"

Stage 2

Deadline on Sunday 6.1.2019 at 23:59

Assignment
Make a believable interior scene of a room by your imagination. You can use models created for the previous stage, create the new ones, or use any publicly available models. All materials should be done by yourself using Principled BRDF shader and additional material textures.
Evaluation
Create custom UV mapping for 3 complex models. (15p)
Correctly set up materials (10p)
Textures used to control at least 4 material parameters (5p)
Used at least 2 procedural textures (5p)
Used displacement map (5p)
Scene logically separated into several layers (5p)
Aesthetics and believability of two final renders (5p)
Bonus: Use 3 textures edited/created by yourself. (3p)
Bonus: Use compositing node editor to create final touches to renders: bloom, color and contrast adjustments etc. (5p)
Submission
Before modeling create folder named "mrt_p2_[your name]" and place all files inside that folder.
Folder should contain ONLY ONE blend file and all required resources as well as final renders.
Create a text file in a folder and white down notes - which models are yours, which uv coordinates you createdm, which textures you edited/created, etc, to distinguist what was downloaded and what was made by yourself.
Pack folder to archive (zip/7z/rar) and send to adam.riecicky@fmph.uniba.sk with subject "MRT Project 2"
