generate 3d light trail with kinect


    Sep 06 2013 | 1:43 pm
    hello guys,
    I'm going crazy to create jitter in the light trails in 3D space.
    I would like to transfer the xyz coordinates of the Kinect to draw a trail in 3D.
    I'd like to get this result to create light trails
    I'm just enough :)
    does anyone know how to do it? or has already created light trails?
    please help me
    thanks
    Mauro

      what have you tried?

      Chiming in here, as my issue is related - Not strictly the 'light trail' effect per se, but rather to create (the illusion of) a continuous path of arbitrary length in 3d space
      The approach I have tried is to use jit.gl.sketch to draw a shape in 3d space using stroke commands. Unfortunately the system slows down quite drastically as the path grows longer - No doubt as a consequence of the fact that the system is defining an ever longer path based on freehand gestures (displaylist 1 has some effect but it is still slowing a lot).
      So I guess the problem is to either render the path to a texture at some point before the path bogs the CPU/GPU down and then somehow place that texture in the render context so it gives a good sense of continuity, or alternatively to find a more efficient way to draw (or perhaps define) paths of arbitrary length possibly using a some other method. Unfortunately, I haven't really managed either yet.
      Any tips welcome...

      jit.gl.path?
