NonCAD 3d Modelling Systems

1
Non-CAD 3d Modelling Systems

• Other 3D graphics systems

2
A working definition

• (The use of computers in the design process)
• Takes a different approach to modelling, often
  using a mesh rather than just 3d primitives
• There are also specialist software solutions for
  a variety of applications

3
Software Packages

• General modelling systems
• 3d Studio Max, Maya, Cinema 4D, POVRay
• Specialist packages
• Humans
• Poser, 3d-me-now
• Landscape
• Bryce, Vue D-Esprit, Terragen..
• Motion
• CAT, Motion Builder

4
3d Studio Max

• One of the industry standard applications
• Used in film and multimedia production
• Operates by allowing the user to perform
  modifications to graphics elements
• To change shape
• To create new objects
• To skin for texture and animation

Google Sketch-up

• A free modelling package from Google
• Can export models for display in Google Earth
• Works along similar lines to Max in that
  modifications are made to standard elements

10
3d Me Now

• A system for modelling faces based on photographs
• Complete with speech synthesis and basic
  animation
• See a bad example

11
Vue dEsprit (and similar)

• Bryce and Vue d-Esprit are designed to create
  landscapes
• Generally these are imagined rather than real
• See demo

Poser

• Poser is the flagship package for creating and
  animating figures
• It has its uses
• There is a large user community who make nice
  pictures of virtual people just for the fun of it

Digital Lego

• Naturally, Lego exists in cyberspace!
• There is a free program that allows users to
  create Lego constructions
• This can then be rendered or exported into other
  applications

17
Data Input Systems

• 3d digitisers
• Modelling over sketches
• Photogrammetry
• Laser scanners

What this leads to

• Beautiful rendered images of real and imagined
  environments
• Animations and visualisations of creatures,
  environments and objects
• Abstractions of reality
• The CG movie industry
• Museum exhibits
