== 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
 
; Evaluation
: Create uv coordinates and textures for at least 3 models.
+
: Use correct modelling techniques for each model category (20p)
: Use '''Blender Cycles''' renderer and use emission material instead light objects.
+
:: ''Simple Polygonal'': extrusion, inset, loop cutting...
: Use at least one of each: bump map, displacement map, specular map.
+
:: ''Curve'': curves, screw modifier...
: Create one representative rendered image of you scene.
+
:: ''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
 
; Submission
: Follow the rules from Project 01 assignment (do not forget to add rendered image).
+
: 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"
