On my computer I can probably calculate the angle ten times a second; on an XO, maybe once a second. However, this means that during the entire process, the machine is running at 100% CPU, so interactivity may suffer. I had a much simpler idea: overlay the previous frame on the video field, offset by the desired amount (say, 70%). This is what many consumer digicams do in panorama mode, including my cell phone. It is then obvious to the user to turn the screen until the overlaid image aligns with the camera output. Based on the Video Chat/Virtual Whiteboard mockups, it seems like we have accelerated alpha on top of video on the LX, but I don't know this for sure... - --Ben -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGeXtOUJT6e6HFtqQRAg4tAKCRUnPhxTv9sw9jhaco2T8F1ZvsHgCcD57P KzZsMualX8LAr7OhvIKk2vA= =JySx -----END PGP SIGNATURE----- _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
