[X3D-Public] Beyond Viewpoint: X3D Camera Nodes for DigitalCinematography

[Len Bullard]

Aha, machinima nodes.

How will these be easier to author than Viewpoints plus scripts and/or
interpolators?

Subject: [X3D-Public] Beyond Viewpoint: X3D Camera Nodes for
DigitalCinematography

Jeff and I have written a paper for Web3D 2009 Symposium in Germany
next week.

This paper describes four candidate X3D extension nodes: Camera, Shot,
Movement and OfflineRendering. An X3D lexicon for camera movements is
defined so that individuals directing virtual cameras in X3D can directly
apply terms that film directors and cinematographers understand. This
approach greatly simplifies the technical tasks involved in creating precise
camera animations and setting up still images for digital photography.
Further, candidate methods are examined for implementing Depth of Field for
focus control. Moving beyond the typical clumsiness of Viewpoint control can
enable authors to create compelling still and moving images from X3D scenes.

Our initial implementation scene works in 3 different browsers now and is at
http://www.web3d.org/x3d/content/examples/Basic/development/CameraPrototypes
.x3d

The X3D Working Group has agreed to review and consider these nodes
for possible inclusion in the X3D version 3.3 standard.

Comments/feedback welcome.

all the best, Don
