Assignment 1: 2D Drafting & Rendering

Feedback

  • Take the requirements seriously! We are.
  • Focus should be on the quality of the line drawing.
  • Be careful not to let raster graphics distract your line drawing.
  • Your submissions are direct reflection of how much understanding you have of the content covered in class.
  • Don't forget—you are pursuing a professional degree.
  • Your work should be at professional quality as well.

General Issues

  • Not enough focus on line weight quality
  • Missing / incorrectly scaled human figures
  • Incorrect / improper use of scale bars
  • Rasterized line work is unacceptable
  • Colored line work is unacceptable
  • Cursory work is generally unacceptable
  • Poor understanding / representation of ground plane
  • Unclear extent of the drawing
  • Section (cut) lines is NOT the same as profile lines
  • Section lines should represent thickness
  • Be careful with the use of poche (Google it), when in doubt, don't use it
  • Your drawings should represent reality, NOT fiction
  • Shallow use of precedent research

Assignment 2: 3D Modeling & Rendering

Moving on

Assignment 2 Overview

Using the drawings you have created in the previous assignment, you will create a detailed 3D model and renderings of your assigned space. You will first create a 3D model using Rhino with layers organized by materials. You will also choose two photographs of the space and attempt to replicate the photographs by creating photorealistically rendered images of the space using the Vray rendering plugin for Rhino.

Assignment Description

Assignment 2 Overview

Classes 7 ~ 9 – 3D Modeling – Rhino

Classes 10 ~ 11 – 3D Rendering – Vray for Rhino

Assignment Example coming soon...

Assignment 2 Overview

  • Detail-oriented 3D modeling and representational rigor

  • Effective communication of atmospheric qualities of the space

  • Imaginative renderings of users activating the space

  • Insightful inclusion of contextual information

  • Tidiness of work (e.g. layer management, accurately scaled textures)

  • Depth of research insight and inspiration, particularly in the employment of compositional techniques

    • Include as comment on Canvas

Grading Criteria

Assignment 2 Overview

Digital Submission – submit the following files via the course Canvas site:

  • 2 renderings and their corresponding photographs of the space, each as 1920×1080 px (W×H) PNG image files

  • Research images, citations, and descriptions of how they have served as your source of conceptual and graphical inspiration, in a single 1920×1080 px (W×H) PNG image file

  • 1 Rhino and texture files, all packaged into a single ZIP file

Final Deliverables Due Oct 23 at 10:30am

Assignment 2 Overview

  • PNG files must not have transparent background.

  • One of the renderings must be in grayscale with no textures (clay render).

  • The 3D model shall have optimal geometric, material, and layer organization.

Assignment 2 Overview

Steps

  1. Import AutoCAD drawing into Rhino
     
  2. Set up and use AutoCAD drawing to create your 3D model in Rhino
     
  3. Choose 2 views / photographs of your space that you will match.
     
  4. Set and save views in Rhino to match the photographs.
     
  5. Tweak render settings and materials to match the photographs.
     
  6. Create final renderings.
     
  7. Add finishing touches to the final renderings in Photoshop.

Assignment 2 Overview

Tips

Model towards the views you have chosen—do not attempt to model the entire building. Model just what you need for your views. Be smart (not lazy) about what you model.

Focus on natural lighting qualities—the priority should be on representing the lighting quality of the space. Be careful not to waste too much time on textures and artificial lighting.

Create accurate representations—if you are using textures, make sure they are properly scaled and accurately represents reality.

Polygons vs. NURBS

Polygonal Modeling

NURBS (Non-Uniform Rational Basis Spline)

Based on Mathematical Model, Higher Level, More Intuitive

Points (Vertices) > Curves > Surfaces (Abstraction that's ultimately rendered as polygons)

Points (Vertices) > Triangles (Mesh)

Lower Level, Less Intuitive, More Efficient for 3D Rendering

Boolean Geometric Operations

All 3D computer graphics abstractions are fundamentally comprised of small triangles (facets, faces, etc.)

Through the process of Tesellation

Graphic Tessellation

Architectural Tessellation

Number of vertices needed grows with the amount of curvature in the geometry.

Try to imagine how many vertices/faces would be needed to model thin "piped" geometries.

e.g. Modeling hair is a difficult computational problem.

NURBS

Mesh (Polygons)

For this assignment, you will work mainly with NURBS

Except when you use 3D models from the web (e.g. 3D Warehouse), which will be in mesh (polygons)

Due Next Class

2 photographs of your space

One of these must be rendered in greyscale with no textures (Clay Render)
