Interactive Models from Images of a Static Scene


FXPAL’s Pantheia system enables users to create virtual models
by ‘marking up’ a physical space with pre-printed visual
markers. The meanings associated with the markers come
from a markup language that enables the system to create
models from a relatively sparse set of markers. This paper
describes extensions to our markup language and system that
support the creation of interactive virtual objects. Users place
markers to define components such as doors and drawers with
which an end user of the model can interact. Other interactive
elements, such as controls for color changes or lighting
choices, are also supported. Pantheia produced a model of a
room with hinged doors, a cabinet with drawers, doors, and
color options, and a railroad track.
