hello all

any help would be great, i am just abit stuck….

the problem is that when the hours hand is moved more than a couple of hours at once, the second hand spins around and around very fast and it looks like it jumps from one place to another, i would like the second hand to move smoothy.

the patch will be use as a touch screen, as a user you with press on the hour hand, as you move the hour hand around it will move a video backward and forwards in time, this bit is sorted its just a bit of background.

it got some loadbangs

thanks in advance

Ben

just had a look, isnt it just a case of the second hand moving so fast that your frame rate cannot cope to display the steps?

setting the qmetro to 5 and removing the speedlim object worked for me.
i would recommend toggling the @sync attribute of jit.window and determine which looks better. i would guess enabling sync is the best solution.

but yeah, as in all computer graphics your limited by your display refresh rate.

thanks for the relays, it does look better with sync on, yeah i think it is the frame rate, i have set the second hand to be *3 instead if *12 too, it not accurate any more but i dont think people will care.

thanks ben
