FILM A three minute film
demonstrates with visual and aural simulation the
architectural design of a concert hall. The film starts with
a photograph of the cathedral before reconstruction work
begun there, and is followed by walk-through in the planned
vestibule. At the same time non-auralized, monophonic music
is heard in the background and when entering the concert hall, the
music becomes auralized. Inside the hall the sound is
rendered according to the hall acoustics. The simulated
soundscape follows the view of the camera as it moves
through the hall.
Technical details
The concert hall model is based on architectural sketches
and the film was rendered with 3D StudioMax (models and
animation) and Lightscape (radiosity) software. The
auralization (i.e. creating the 3-D soundscape and modeling
of acoustics) was done with DIVA software. DIVA software
models sound propagation from sound source to the listener,
taking into account the reflections from walls, floor and
ceiling as well as frequency dependent sound absorption in
the air. More information about the DIVA auralization system
can be found here.
St. Marienkirche, located in Neubrandenburg, Germany is a
13th-century gothic cathedral. It was ruined at the end of
World War II. The cathedral is currently being rebuilt as a
concert hall. The work will be completed at the year 2000.
