Abstract
Realtime rendering requires accurate display of a dynamic scene
with minimal delay. Frameless rendering
offers unique flexibility in this regard: because it samples time per
pixel, it can respond to change with very little delay, and at any
location in the image. However, sampling is random, resulting in
blurring in changing image regions. We present an approach for
improving frameless rendering by making sampling sensitive to
change in the image, as suggested in . By
measuring this change in visual terms, we are able to direct
sampling to those regions of change. The resulting algorithm
produces sharper imagery, while introducing minimal overhead
into the standard frameless algorithm.
will examine the use of our change sensitive approach in the
context of distributed rendering .
