Modesto selected Tadao Ando's Kidosaki House
as a subject for simulation.
Ando's buildings are constructed with a signature concrete block style.
These blocks include recognizable round indentations
that can easily be approximated using texture maps.
It seemed that the radiosity algorithm
could easily simulate the lighting in such buildings.
In practice, the high contrast between
outside brightness and inside darkness made it difficult
to generate an acceptable solution.
This photograph from the house shows
an interesting feature of the living room.
There is a narrow window in the ceiling
which runs along the edge of a curved wall.
The shadow cast through this opening
is an important aspect of the lighting solution.
Using Lightscape software,
a radiosity solution was completed and
this ray traced image was generated.
Notice in the photograph that light is specularly reflected
from the glossy floor onto the ceiling near the window.
A more sophisticated global illumination algorithm
would be required to simulate this particular light transport.
