But I think it's only good for diffuse materials (which is also a limit of the frame averaging technique)<br /> <br />Some time ago, I read a paper by Vlastimil Havran on exploiting interframe spatio-temporal coherency with bidirectional path tracing: http://www.mpi-inf.mpg.de/resources/anim/EGSR03/ . This might also work.Sam Laperehttps://www.blogger.com/profile/05688552048697970050noreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-68937201756881533312010-07-02T13:22:57.896-07:002010-07-02T13:22:57.896-07:00I have tried the demo and it was really impressive...I have tried the demo and it was really impressive!<br />Frame averaging however looks really ugly, especially with moving objects.<br /><br />I wonderer if the authors are considering the use of reprojection cache: http://www.cs.princeton.edu/gfx/pubs/Nehab_2007_ARS/NehEtAl07.pdf . I thing that it could help.sebhhttps://www.blogger.com/profile/14650504326449432531noreply@blogger.com
