Hey all,
I'm experimenting with animation in J for a new video... I'm use the wd timer to make an animated plot, and it mostly works, but the window itself disappears and reappears on every frame, causing an unwatchable flicker effect. How can I keep the plot window from flickering, or pipe the output to an isidraw in my own window? Here's a simple sine wave example to demonstrate the problem. (Running in j807 / jqtide) NB. warning: put this code in the j editor before running, or NB. you may wind up having to kill your j session... load'plot' step =: 0x sys_timer_z_ =: 3 : 0 n =. step_base_ =: step_base_ + 1 NB. plot wants to focus on the window, and if you don't use NB. wd to refocus on the editor, your session will become unusable. wd 'sm focus edit' [ plot 1 o. 8 %~ n + i:32 ) wd'timer 50' NB. change this to 0 to stop the timer ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
