 +
 
 +
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"
 +
 
 +
=== Stage 2 ===
 +
'''''Deadline on Sunday 5.1.2020 at 23:59'''''
 +
 
 +
; Assignment
 +
: Make a believable ''interior scene'' of a room by your imagination. You should use models created for the previous project stage, and create some new ones, or use any [http://tf3dm.com publicly available models]. All materials should be designed by yourself using the node editor.
 +
 +
; Evaluation
 +
: Create custom UV mapping for 3 complex models. (12p)
 +
: Correctly set up materials for the entire scene (10p)
 +
: HDR environment map (5p)
 +
: 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 collections (3p)
 +
: Aesthetics and believability of final renders (5p)
 +
: ''Bonus: Use 2 textures edited/created by yourself. (2p)''
 +
: ''Bonus: Use compositing node editor to create final touches to renders: bloom, color and contrast adjustments, etc. (3p)''
 +
 
 +
; Submission
 +
: Before modeling create a 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 write down notes - which models are yours,  which UV coordinates you created, which textures you edited/created, etc, to distinguish 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"
