Cyclorama

  • In 1787 Robert Baker was awarded the patent for “La Nature a Coup d’Oeil”.

(Nature at a Glance)

  • What we now call the cyclorama, large paintings often presented on architecture

matching the place represented in the painting. Heightens the suspension of belief, the sensation of “being there”.

“... to make observers,

  • n whatever situation he may choose they should imagine themselves,

feel as if really on the very spot”

Charles Chase

  • In 1896 Charles Chase employed recent advances in photography to create more

literal panoramic experiences.

  • Targeted virtual tourism

“... everything in view from the point where the photograph is taken will be reproduced exactly as it appears when seen from such point” “By this manner of reproducing views a person can get a better idea of the different parts of the world without actually going there than in any other manner heretofore devised. In fact he may see such views exactly as they would appear if seen on the ground”

Video Panorama

  • The next logical step is video panoramas
  • A number of cameras available for this although most are low resolution
  • Early (first?) large scale application was in 1957 at the Hamburg planetarium.

Motivation for Visualisation

  • Visualisation employs advanced algorithms and computer graphics to provide

insights to researchers.

  • Value in maximising the capabilities of the human visual system.
  • In the context of the panorama this involves images that
  • 1. capture everything visible from some position
  • 2. present the panorama so as to give a sense of immersion
  • 3. form a convenient format for extremely high resolution digital recordings
  • Recurring themes from 200 years ago
  • 1. create a sense of immersion, of being in another place
  • 2. create highly realistic and detailed representations

Spherical panorama video: Cultural heritage

  • A number of cameras have been built that can capture spherical panorama video.
  • Employed in visualisation in cultural heritage: providing insight into a different

culture.

Cylindrical panoramas: Virtual heritage

  • If the vertical field of view is limited then referred to as a cylindrical panorama.
  • “Cylindrical” refers to the fact the image wraps around in longitude,

left and right edge join seamlessly.

Gigapixel panoramas: Recordings in archaology

  • Gigapixel refers to the number of pixels in the image.

A good SLR camera may capture 20+ Megapixels, how to photograph at 1,000 Megapixels?

  • Cannot buy arbitrary high resolution sensor, solution is to stitch large numbers of

images together.

  • Capture detail and the context in one image.

May or may not be a full cylindrical panorama.

  • Results in a much richer digital recording than
  • single image of the extended area but no ability to zoom
  • lots of single images of small parts of the scene
