Yep. Adobe were advertising for people to work on GPU algorithms a year or so back, so I was expecting the first fruits to show up around now. I did a quick estimate based on the architecture of the nVidia cards and reckoned that it should be possible to do a pretty fast Panorama stitcher; a short amount of identifying alignment points (maybe a few seconds), and then real-time pan-and-zoom on the composite image (all working directly from the original bits - no need to actually build a big panorama image). -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
