  I don't think Photon would agree with that definition where only visuals matter :) For example, I could make a glenz vector with my vector player that looks exactly the same as one programmed in real time (or with precomputed transformations), but with many more faces and bigger. And in this case, and without setting a precedent, I would agree with Photon that a vector player should not count as a glenz vector record even if it is visually indistinguishable.
  
  For me, the visual result would be a necessary but not sufficient condition. The technique behind the effect is also important.
  
  My objection was that I had always approached this challenge as copperchunky (or what I understand a copperchunky to be), all the prods that have participated in the challenge before this one have talked about copperchunky and I have restricted my ideas to that category. Removing that term from the challenge now opens up new possibilities, which is great because maybe the challenge on copperchunky was already dead.

  That definition makes sense as well. With the risk of sounding like Photon, I would postulate that 59 is the maximum achievable for 4x4 under these constraints. Do you agree?

  
  I think so, unless Photon or someone else proves otherwise :)

  About visual end result, HAM7 chunky is superior imo, not only because it is faster and allows to do more blocks (for example, 80*49=3920 in Inside the Machine), but also because it has less restictions in size and best visual quality, as you get a blurring that camouflages the big pixels.
  
  Then, being these alternative techniques to HAM7 visually inferior, for me this was always a technical question about the limits of copper, as I answered to Bifat when he asked me about the sense of this competition: "The insistence on real 4x4 copperchunky is because it forces you to face the limit of moves that the copper is capable of per scanline. This makes it a more interesting challenge than simply beating the total number of chunky pixels with no restrictions on pixel size."
  
  But, from now on we could remove the term copperchunky from the equation and make the competition broader, e.g. widest 4x4 RGB rotozoomer.
  Btw, 100% copperchunky in my opinion is when the copper sends all color values to the registers, regardless of how many times it has to send the same pixel, while the CPU only writes each pixel in the copperlist once.
  
  Regards and congrats again!

• * I must correct a typo in my previous comment, it is 1049, not 1072.

• Hey, congratulations Blueberry and all the team!
  
  I would have loved to be in Posadas to see it first hand and feel the adrenaline in the compo :D but unfortunately I couldn't be there this year.
  
  What a great presentation!, Graphically and musically a pleasure. In your eagerness to fight the Joker, have you thought about joining the Batman Group? hehe xD
  
  But there are still some small quibbles I have to make about some of your world record claims.
  
  I was just talking about it with Hannibal in the Boreal Dust comments: when it comes to setting records, it is sometimes confusing to establish what is or is not the same type of effect. For example, in this case the effect is not a 100% copperchunky, as at least half of the pixels are written to the colour registers with the CPU instead of the copper. So I would say that the record of columns in a 100% copperchunky 4x4 still belongs to the Joker. Don't you agree?
  
  On the other hand, in the first secret part of Joker Snacks on Blueberries there are 57 x 64 = 3648 blocks (same as yours but in different aspect ratio :), so here you have equalled, not beaten the biggest 4x4 RGB rotozoomer on OCS running 50fps with scroller and music record :)
  
  In any case, thanks for keeping the competitive spirit of the demoscene alive and congratulations on your "Widest 4x4 RGB rotozoomer on OCS: 64 columns" record!

  Yes, this is not exactly the same effect as Leonard's, since, as you say, his is a single sine dots and this are 8 mixed sine dots of 1072 each. To illustrate the difference a little better, this is what happens in each frame in both effects:
  
  Chips & Dots:
  
  frame 1 -> 7210 sinedots at sinY pos 1
  frame 2 -> 7210 sinedots at sinY pos 2
  ...
  
  Boreal Dust:
  
  frame 1 -> 1072 sinedots at sinY pos 1 +
  1072 sinedots at sinY pos 2 +
  1072 sinedots at sinY pos 3 +
  1072 sinedots at sinY pos 4 +
  1072 sinedots at sinY pos 5 +
  1072 sinedots at sinY pos 6 +
  1072 sinedots at sinY pos 7 +
  1072 sinedots at sinY pos 8
  
  frame 2 -> 1072 sinedots at sinY pos 2 +
  1072 sinedots at sinY pos 3 +
  1072 sinedots at sinY pos 4 +
  1072 sinedots at sinY pos 5 +
  1072 sinedots at sinY pos 6 +
  1072 sinedots at sinY pos 7 +
  1072 sinedots at sinY pos 8 +
  1072 sinedots at sinY pos 9
  ...
  
  And since there are 8 different sine dots, I also draw each one with its own movement in different screen areas.
  
  We could call this a "multi sine dots" vs the classic single sine dots (or simply sine dots). In any case, I think the most difficult part of record-keeping is defining the different categories, as it is sometimes confusing to establish what does and does not belong to the same type of effect.
  
  Btw, I think both routines are based on yours from 3d demo 3, but looking for a way to draw more dots by taking advantage of the address registers :)

• Drawing 8392 individual and unrepeated sin dots per frame and shown as 100704 dots in 4 bitplanes and 171 colors. Enjoy!
