Introduction
This piece is meant to be used for an introductory demo to 3D technologies, in particular with respect to 3D contents on the Web, 3D applications that use the Internet, and 3D models that share over the Internet.
3D and the Internet
Introduction to computer graphics
Three main stages:
- Modelling
- Adding animation and interactivity
- Layout and inserting into a larger scene
- Rendering (displaying)
Modelling principles
Animation
Computer animation means generating animated images by using computer graphics. Technically speaking, animation just displays various "pictures" over time (about 24 frames/second). But from a modellers point of view, most animations are now created through some sort of manipulable skeletons.
Let's have a look at avatars, i.e. some kind of "puppets" that are used in various application areas such as video games and virtual worlds. One popular technology defines an avatar as:
- skeleton that is composed of connected bones representing various body parts
- a skin
Sometimes avatar movement is obtained through studying or capturing living persons.
interactivity and scenes
Application areas
Below we show a few examples of application areas, several of which may share the same technologies.
Industrial design
CAD/CAM
Architecture
Movies
“Computer-generated imagery (CGI) is the application of the field of computer graphics or, more specifically, 3D computer graphics to special effects in art, films, television programs, commercials, simulators and simulation generally, and printed media. The visual scenes may be either dynamic or static.” (Wikipedia)
- First movies that used 3D were Westworld (1973) and Futureworld (1976).
Medecine
Several areas:
- Medical imagery
- Anatomical models for training
- Computer-assisted surgery
Virtual worlds and Games
Games are built using so-called game engines
Data visualization
