Original Kurzfassung:
Computing the correct illumination of virtual
scenes is a well-explored area today. Most commonly
used 3d graphic libraries like OpenGL or
DirectX/Direct3d contain functions for these tasks.
Within the field of real time mixed reality, the
problem of correct illumination (i.e. consistent with the
real illumination conditions) has not been considered
much, because there where, and still are, more severe
tasks to cope with, like for instance commonly usable
tracking solutions or conveniently usable end user
devices. But one of the main reasons for this is that the
properties of the real light source cannot be determined in
real time. There are some approaches like [1] and [2] that
try to overcome this problem by conventionally tracking
the position of the light source, or by using projectors as
light source, which also project shadowing effects. This
approach works perfectly for well controllable in-door
setups but it fails for out-door applications.
