Sirius - Virtual Reality Systems Management based
on computer clusters
Immersive multi-projection systems are complex environments
that became even more sophisticated with the use of computer
The propose of the Sirius solution was to provide a clear
interface to the applicatives and devices management for the
Virtual Reality Nucleus infrastructure.
The Sirius project is a graphical interface, implemented in
Java, which considers a heterogeneous cluster node system.
Actually, Sirius can control the light, video, tracking and
audio systems, the robotized cameras and demonstrations. Every
operation and problems are recorded (on logs), for future
depurations and use control.
JINX - 3D Virtual Environment
JINX is a fully distributed virtual environments browser,
which has a special support for commodity computer clusters
and immersive visualization devices. The presented mechanism
intends to be fast and easy to use to develop virtual reality
applications based on the X3D format, enabling great flexibility
for displays and interaction devices, allowing users to concentrate
only on content creation. JINX provides support for nodes
synchronization and resources sharing, from Framelock to Datalock.

The Cathedral Project – a virtual tour at Sibenik
The project describes a virtual tour through Sibenik Cathedral.
The production was made through the conversion of a cathedral’s
model from 3DMAX to ASE, which then, is loaded to the memory.
OpenGL structures were used to renderization.
The renderizations are distributed between the graphical cluster
nodes and directed to the Digital CAVE. Actually, the navigation
can be done through wireless devices from inside the CAVE,
without the need of a second character controlling the navigation.
– Virtual Hang-gliding over Rio de Janeiro
By the perspective of a hang-gliding, the user can performance
a virtual aerial tour through the city of Rio, visiting the
most traditional touristic points. To complete the sensation
of immersion – provided by a HMD (helmet-mounted display)
type, 3D visualization system, the user can figure on with
environmental music, besides sounds geographically disposed
over the sambódromo and the Maracanã.
Actually, the system has been imported to the Digital CAVE.

Glass - Library for distributed
Glass’s objective is to improve the development process
of applications based on graphical clusters. This library
was developed on C++, in a way that offers data abstraction
and independence of another libraries. In that way, the common
data and others types can be created and manipulated; besides,
the already available solutions can be reused. The reutilization
of other libraries is a developer option, which can, by example,
utilize OpenGL Graphical Library or OpenGL Performer to applicatives
implementation. a binding for Java is under development. (Just

OP_ERA – Artmedia at Digital CAVE
OP_ERA is an immersive-interactive environment created by
Daniela Kutschat & Rejane Cantoni, where the visitor and
the space around him were realized like mutant integrated
fields. Produced by the Virtual Reality Nucleus, the environment
was installed at Digital CAVE.
- Research and development of scientific and artistic space
- Human-machine interfaces (hardware and software) specially
drawn for immersive-interactive environments, which the
human and artificial (computer) agent is symbiotically interconnected;
- Alternative spatial perception and cognition ways through
multidimensional experimentation of conceptual space models.
IMERSIVE AUDIO FOR COMPLETE VIRTUAL REALITY SYSTEMS
Research and implementation project of a flexible and scalable
system for three-dimensional audio reproduction at the EP-USP’s
Digital CAVE. Objectives includes since the implementation of
decoder systems for traditional surround formats (like 5.1,
7.1, 10.2, DTS, Dolby Surround) to the development and availabilitation
of more complete formats for 3D audio generation and reproduction,
still restricted to high-fidelity and research environments,
where not only the surround reverberation and the envelopment
are important, but mainly the sonorous objects locations distributed
in a three-dimensional scene, and the acoustical environment’s

Wireless Stereoscopic Video Transmission
The prototype constructed at the Digital CAVE allows stereoscopic
video capture, transmission and reception. A helmet composes
such prototype where there is two connected cameras. The video
capture is synchronized. This video is encoded and transmitted,
through wifi 802.11, technology, to another computer connected
to the net. The system is all mounted inside a hunchback, becoming
weightless and portable, that allows the user a free movement
inside the wifi net reached area. (Just
