pavilion > views (interiors).
These photos are internal views of the Philips Pavilion, with overviews and
details of the ceiling (pinnacles) and lighting equipment.
One can notice that some pictures were taken during construction works.
In pictures of the finished pavilion one can see the loudspeakers over the walls:
these pictures were used for retrieving the positions of loudspeakers through a
photo matching process.
A similar slide show is for the
exteriors.
