jit.gl.sketch, curves and aliasing


    Feb 01 2014 | 1:52 am
    Hello everybody,
    As jit.gl.path doesn't support customizable texture coords (as fas as I know), I'm trying to animate and draw textured strokes with jit.gl.sketch and I'm astonished by aliasing. In the patch below, points of jit.gl.path animated by jit.phys are sent to jit.gl.sketch to draw a textured stroke. Here is a screencap showing the aliasing.
    Does anybody know how to reduce it ? I tried (quickly) FXAA shader without success.
    I'm despairing of drawing nice strokes with Jitter, please, any advice is welcome
    thanks

      hi, Cool patch, All works fine here, maybe your problem is only a Texture scaling...

      Thanks for your reply Matmat,
      You get a smoother line than I do ! Have you changed any parameters on the patch ?
      Here is a fullscreen capture (1920x1080) from the patch below (with fixed values), may I ask you to take a screenshot of what you get to compare ? Maybe it's hardware dependant, what's your graphic card ?
      thanks,

      It's better, you're right, thank you for the tip but ... do you know why it's better with these dim ?
