When a rendering algorithm has created a pixel array of radiance
values the task of producing an image is not yet completed. In fact,
to visualize the result the radiance values still have to be mapped
to luminances, which can be reproduced by the used display. This
step is performed with the help of tone reproduction operators.
These tools have mainly been applied to still images, but of course
they are just as necessary for walkthrough applications, in which
several images are created per second. In this paper we illuminate
the physiological aspects of tone reproduction for interactive
applications. It is shown how tone reproduction can also be
introduced into interactive viewers, where the tone reproduction
continuously adjusts to the current view of the user. The overall
performance is decreased only moderately, still allowing
walkthroughs of large scenes.
