Rotating objects in a jitter Matrix

    Nov 08 2010 | 6:26 am
    Hi everyone. This is my first post. I have been using Max for a couple years, but I really haven't gotten into jitter at all. My focus has been in audio.
    Currently, I am working on a patch that is creating a cross section of an environment through audio. Without getting into a lot of unnecessary detail, I am looking at spatializing audio within a three dimensional (8.1) matrix. I have created a visualization of this in jitter, and have been able to emulate many of the audio processes visually this way (generally motion and growth). I am using this for debugging and monitoring the system, so my limited jitter skills haven't been too great of a hindrance, so far. But one this has left me kind of stumped.
    My question, which seems like it is extremely simple, is; how do you rotate the objects? Most of the objects' rotation does not matter, but there are certain objects (the cylinder object to be exact) that I would like to extrude in a particular direction (to emulate growth). I know in the help file for jitter.sketch shows the rot message, but I could seem to get it to work.
    I would like to be able to set the direction the object is facing with a loadbang, nothing dynamic is needed.
    Thank you, and my apologies for my newbness, I have generally relied on others to work the jitter component in the past, so much of it is foreign to me.

      I'm not sure I understand what you're trying to do but maybe jit.rota will serve your needs? If not, there's always the rotate options in GL (the rotate or rotatexyz attributes.)

      try rotatexyz first, for objects like your cylinder (which I'm assuming is a scale X Y Z will let you extrude in whatever direction. Also check out poly_mode so you can see it as wireframe or points (with line_width and point_size attributes), often this helps see better what's going on as you tweak things.
