Slideshow & pixelation


    Aug 04 2019 | 2:36 pm
    Hi everybody,
    I created a random and faded slideshow, very simple.
    I am facing a problem that I can't solve : you can see on the screenshot. On the left, the slideshow ; on the right, the original picture. The more the details are thin, the more a pixelation appears. It is obvious on this picture, close from the sunlight ; the difference is not so big, but it's to much. Can someone help me about that ? Best,
    Bastien.

      Try jit.world @high_res 1

      Hi Martin, I've already try but it does nothing. Actually I found this topic https://cycling74.com/forums/jit-world-texture-dimension
      But I can not understand the solution.

      Can you please specify your Max version and Mac or Windows ? I think for windows you have to enable an option called "high dpi ..." in the preferences section of Max. Using @high_res 1 (and maybe you also need @fsaa 1 ) solved all my problems regarding jagged lines issues.

      My version of Max is 8.0.6 used on macOS Mojave. Well, I would like to try your solution, but could you specify where do I have to insert those arguments (fsaa & high_res) ? I've already tried it but maybe not at the good place. Thank you again.

      Hope this helps.
      I am not sure if the rescaling that you apply by the size attribute might cause some trouble.

      I finally found the answer ! I needed fsaa to be checked and output texture. The pixelation comes from that output matrix is checked by default. Now I have a a last problem : fullscreen mode of jit.world does not keep the original ratio of the picture. I would like to display fullscreen with black stripes on both side of pictures because they do not have a fullHD ratio. Would you know the way to keep the original ratio in fullscreen mode ? Bastien.

      Draw everything to jit.gl.node with fHD dimensions and set erase_color of jit.world to black.

      Just add a "@preserve_aspect 1" to jit.gl.videoplane.
