Regards, Problem with scenegraphs is that they have to be copied into final frame, which wastes bandwidth. I was thinking that in some circumstances it could be done so that: - copying is avoided - frame drawing is merged with scanning. That is, one could read data and modify it just before it is to be scanned and sent to display. That way, data read is in the cache and can be read from there by picture generating circuitry. It also changes the way primitives are drawn - scanline by scanline. As I understand, under Wayland there is a way to work with a window frame without it being copied to main picture frame. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
