Fig. 5: Object-based models allow for the control over all parameters for each mesh.
This provides a flexible tool for reproducibility under test conditions. (Own illustration)
The architect still misses – in most of the cases – the feedback
of the user of buildings in order to modify his/her design.
We finally Real-Time render the environments
using the Unreal Engine for visualization
and the RAVEN room acoustics
simulation engine for auralization.
In the case of photogrammetric captured
environments, light transfers are
extracted directly from the visual data,
since they contain real illumination. The
acoustic cues can be recorded or simulated
from an acoustic model.
• Colors and shadows are printed in
the textures.
• This technique is specially suitable
for complex geometries, normally
present in historic and monumental
architecture.
• Acoustic models can be derived
from the geometries and textures.
For object based models, lighting is calculated
and rendered on the platform,
in order to achieve the immersive experience.
• Both backed light or real time renderings
can be rendered with object-based
models
• Acoustic models are extracted
and simplified from the visual models
taking care of reflection and
diffraction.
• Lighting and texturing are rendered
independently. -
