“Synthetic computer-generated imagery is not an inferior representation of our reality, but a realistic representation of a different reality.”

The successive phases of the image:
1. It is the refl ection of a basic reality.
2. It masks and perverts a basic reality.
3. It masks the absence of a basic reality.
4. It bears no relation to any reality whatever: it is its own pure simulacrum.
Jean Baudrillard, Similacra and Simulation, 1985

relatively fast process yielding bitmap data by sorting and drawing visible polygons from furthest back to fur-thest forward in the picture plane

slow process yielding coordinate data by determining where opaque polygons “cut” lines and edges

3D RENDERING
Real-time rendering: for interactive media (games, simulators, modeling pro-grams), usually polygonal and not intended to be photo-realistic
Non-real-time rendering (prerendering): used in feature fi lms and architectural competitions, photo-realistic renders employ one of the following techniques:
- scanline rendering - considers the objects in the scene and projects them to form an image with no facility for generating a perspective effect
- ray tracing - considers the scene as observed from a specifi c point-of-view, calculating the observed image based only on geometry and very basic opti- cal laws of refl ection intensity
- radiosity - uses fi nite element mathematics to simulate diffuse spreading of light from surfaces
- unbiased - rendering equations based on physical equations of light transport

atmosphere
“Regardless of their design philosophy, architects try to capture the less tangible effects of a construction, waving their hands around representa-tions of their projects like impassioned spiritualists, drawing invisible lines of force and predicting the arrival of certain intangible qualities.”
“The viewer of the drawing is meant to experience something of the building’s atmosphere. Drawings are atmosphere simulators and even the most abstract lines produce sensuous, unpredictable effects.”
- Mark Wigley (1998), “The Architecture of Atmosphere,” Daidalos 68
