How to plunge my vector & points distance calculations into gen for efficiency ?

    Jun 10 2012 | 9:47 am
    Hi there,
    diving in GenExpr with jit.gen for better efficiency.
    As dtr suggested here:, I'd like to use jit.gen for a (basic) calculation.
    I have my vector coming from my cam view (position, orientation) & a point (position).
    I need to calculate elevation and azimuth relatively to my cam vector (indeed, a & e vary according to the orientation of cam)
    anyone would help me with this apparently easy stuff with gen ?
    swiz seems to be the key.
    but considering a matrix 1,3 (my vector, basically), how can I explode its values to x y & z variables to use them in a codebox inside gen ...?
    ANY leads/helps would save my hour =)

      Hi Julien,
      Are you calculating just a single result or do you have a matrix of positions that you're calculating? If it's a matrix on input positions, I would set things up as follows:
      [param position] // cam position
      [param orientation] cam orientation
      [in 1] // positions to calculate a/e data relative to camera
      If you have a patch, even if it doesn't work, but shows the data you're working with, that would help immensely.

      Hi wesley, answered to that finally, being quite related.
      May I ask you your opinions about the last post I just made ?
      My system needs to be a bit optimized, even at this point.
      Any help from you would be appreciate :)
