[Uni-verse] D2.2 section: End user perspective on functional specification Architects Study

[Peter Lundén]

Hi,

Im very sorry that I have been quite absent from the discussion lately. 
The main reason for this is that I have been overloaded with work in 
other project, it is problem of phasing in this project. Now the 
situation starts to become better and I can use more time for the 
Uni-verse project.

<>I have found what I believe is a misunderstanding of the capabilities 
of the acoustic simulation. In D2.2 section, End user scenarios, End 
user perspective on functional specification Architects Study, WP7 
Acoustic rendering and simulation, it says: "As acoustic rendering only 
uses perceptual attributes, it refers to games, not architecture. The 
use of sound in design lost it’s meaning, for this reason, it can only 
be used for presentation. As the research is targeted to *A Distributive 
Interactive Audio-Visual Virtual reality System*, it loses its goal."

This is not true, a large part of the work in WP7 is about implementing 
an acoustic simulation and rendering that is based on the geometric 
description of the simulated world and physical properties assigned to 
this geometry. The system will be capable of performing a physical based 
simulating the acoustics of the modeled space with good accuracy as well 
as perceptual based simulation. In fact, one of the basic idea of have 
both an architectural application and a game application is to 
demonstrate that the system is capable of handling the two different 
approaches of the acoustic simulation.

I think this is a serious problem and it has to be changed as it gives 
the wrong impression about the system.

What happend with the first ideas of haveing a demonstrator about a 
theather project? That idea was very good for demonstrating the 
different capabilletes of the system including the two acousic 
simulation approched.
