Techniques of Perception in VRML97
Media and Storytelling

artists or teachers, we attempt to evoke emotion or understanding
in our audience by creating a compelling phenomenology: perceptions
of objects, relationships, and situations. Its not The Matrix, Tron, or Total Recall, but Web3D today provides us a powerful toolkit to
convey meaning over digital networks and multiple modalities: modern
virtual environments provide an unprecedented level of interaction
and immersion… and they continue to improve!
the same way as rich-media, we can develop characters, lighting,
sets, define camera shots, scenes, and action.
All of the principles of these disciplines still apply, but
producers are freed from many of the constraints that physics and
physical costs usually impose.
In many cases, models from commercial libraries or pre-rendered
segments may already exist and can be assembled, connected, animated,
and compressed for distribution over the internet.
the media assets are composed and scene’s interactivity programmed,
freedom to navigate the camera to any location means that authors
can do multiple takes and rehearse shots easily.
It is also common to populate the scene with multiple cameras
so that users can see the action from various angles or transport
to different areas of the world. When the camera shot is not pre-defined,
the user is free to navigate the space and examine any part or detail
of the scene… even see the action from different actor’s point of
real advantage to the networked nature of Web3D, beyond distributed
audience reach, is that multiple users can co-exist and communicate
in real-time in the same virtual environment.
In this way, they can influence the course of the action
for each other, and create novel situations and outcomes.
Typically, users are represented in the 3D environment by
personalized 'Avatars' which can gesture, move, and
chat according to their user’s intent.
The notion of presence is a
powerful one that will become more and more important as technology
enables increased realism for networked virtual environments. It also allows for the further suspension of
disbelief when interacting with the narrative or scenario as the
lines of identity and place blur…
I think Tim Leary said, “You
can be anyone this time around”…
The degree of immersion in deep
media will increase as input and display peripherals continue to
improve and take users into Altered
States of being.

and implementation in VRML97.
