Lecture notes for Lecture 23: 3D Modeling: An Overview

Software

Key Terms (NURBS Modeling)

  • NURBS = “Non-uniform rational B-spline”
  • A mathematical model used to accurately represent complex curved surfaces
  • Easily reproducible

Key Terms (Polygonal Modeling)

  • Modeling by approximating surfaces with polygons
  • Similar to physically modeling with clay, resulting objects are solid

Key Terms (Parametric Modeling)

  • An interlinked approach to the design process where small changes re-populate through the design manifesting in larger changes of form

Maya (Autodesk)

  • Advantages
    • NURBS Modeling
    • Animations – evolution of the design through animated tranformations
    • Parametric hierarchy and connectivity
  • Disadvantages
    • Expensive Generic “Maya” unit Lack of precision
    • Not designed for Architects

Rhinoceros (McNeel Software)

  • Advantages
    • NURBS Modeling
    • Precision
    • Command Line Input
    • Trim complex surfaces, create lines at intersections of surfaces, project lines to surfaces, “Make2D,” etc.
    • Interoperable with other 3D programs
  • Disadvantages
    • No Animation
    • Poor rendering out of box (often requires plugins)

3D Studio Max (Autodesk)

  • Advantages
    • Polygonal Modeling
    • Works well with other Autodesk Products
    • Easy lighting/materials/ renderings (tend to have good results without much training)
    • Animations
  • Disadvantages
    • Polygonal Modeling
    • Not designed just for architecture
    • Trimming curved surfaces is challenging
    • Not capable of parametric modeling

SketchUp (Google)

  • Advantages
    • Free
    • Not NURBS, but a hybrid with similar features
    • Quick and easy to learn
    • Quick and easy to produce good models
  • Disadvantages (SketchUp)
    • Exports other than images require pro version
    • Difficulty with curved surfaces
    • Has a “SketchUp” look

Output from 3D Models

  • Renderings
    • Photorealistic
    • Model/Abstract quality
  • 3D Prints
  • Laser Cut Models
