stuttering text on jit.gl.text3d


    May 11 2006 | 11:11 am
    i have a problem with the rendering of scrolling text using jit.gl.text3d. even in slow speed the text motion is not smooth and flickers, and depending on cpu usage it has a slight stutter. the rest of the patch runs very smoothly. i suspect the line object. if you want to look into the patch you have to supply a foder with text files in it.

      hello,
      the flickering effect seems to be caused by hard edges. try turning on anitaliasing( fsaa 1 to jit.window), it smoothed things here, but then say bye bye to erase_color tricks that could help you with temporal smoothing(without fsaa, try lowering erase color alpha until scrolling text makes subtle trails).
      for timing issues, try to use line~ and snapshot~ instead of line, and bang snapshot~ with metro driving gl.render. this can assure that your text will come from right to left in say 7 seconds, regardless of drawing speed; or, for opposite try using bline to make sure increments are synced to rendering metro, so that text would move from right to left for as long as it needs to draw things smoothly(i got a hunch that this and fsaa 1 will do what you need).
      cheers, nesa

      thanx nesa, i changed to bline but the biggest diffrence was uping the metro rate.unfortunatly i am trying to push three diffrent opengl renders (with two diffrent video cards) and even just [erase,bang] gets the cpu hot at 60% with nothing else on..
      the line~ snapshot~ thing didnt change the situation (if i am using it right that is)
