Odd layout in Circle Model

[rcowan]

Hi All,

I decided to use the Circle model for a Boscoyo 24" Wreath. I thought that it would be perfect because the Circle model lets you do concentric circles. The wreath has 3 circles of 18 nodes each for a total of 54 nodes. The display looks good, however, the node layout looks odd. I have attached my Circle model definition as well as the node layout. Notice how the bottom layer goes from 1 to 18. That looks good. However, the second layer starts on 20 rather than 19 and even skips 22, 25, 31. The third layer starts with 38 instead of 37 and then skips 40, 43, 49. Does this seem right? I'm sure others here have used the Circles model for Boscoyo wreaths. Have you noticed any issues?

Yes that node map doesn't look right but can you actually find anything that's not working with the model?

As I have not received my lights or controllers I can't test this in the real world. However, when I added that model to the sequence and then opened it up down to the node level it seemed fine. My concern though is that it's going to treat the missing nodes as null pixels. So my 54 node wreath will actually need 62 nodes.

I wrote the Circle model but I can't remember how that node map gets generated.  I seem to remember doing work to try to make sure the nodes get distributed evenly across the map.  I believe there was a problem with how effects would look when the inner node counts were smaller and not distributing across the map evenly.  So what's probably happening is there is roundoff in the calculations that causes multiple nodes to think they are landing at the same spot so you only see the second one but in reality they are both there and will work in real life.  You don't need your lights just drop effects on the model and node and watch the preview.  If the lights work in the preview they work on the real lights.  I tried effects at the model and node level and with the circle as part of a group and couldn't find anything not working.

I played with this a bit just to see how it worked.

Your 18,18,18 (3 concentric circles with equal number of pixels) seems to be confusing the algorithm.

When I tried several models using decreasing counts, it seemed to work just fine.

I set one model with 105 pixels total, using 60, 30, 15  and it was exactly laid out in the view.

Thanks Gil and Jon.

I played around with it some more in the sequencer and it definitely doesn't flow right. I plan on making a video in a bit to show what it is doing. Unfortunately the wreath model that I am working with from Boscoyo is laid out that way with 3 concentric circles of equal pixels. I may just have to use a custom model. I was wanting to use the circle model so that it would separate out the circles. That way I could sequence them separately if I wanted. I believe I can accomplish this with a custom model and the Names feature but I haven't played with it yet. If all else fails I can just make 3 individual circles and group them.

Glad to see this thread.  I totally forgot about this issue until now.  Yes, when using same size number of pixel circles, it doesn't quite work the way I expected (not necessarily wrong, just didn't work for me as I would have thought).  I just ended up making a custom model and moved on.  (I have a 4 foot wreath with three rings of decreasing circles of 50 pixels each and 2 two-foot wreaths both with 2 rings of 25 pixels - put it all together and it's a bears a great resemblance to Mickey Mouse according to my viewers but I would never call it that - wink, wink).

I see a checkin today that probably fixed this.

Well I didn't update to the new code yet because I wanted to test what was there first.  I can place a Fan effect on the Circle and put it in Per Preview Render Style and it works just fine so I still see nothing operationally wrong with what was there.

Yea, but the interesting thing was that I only saw the issue on Windows, not the Mac.   No idea why.

I think it will be OK. I was attempting to use a single strand effect and wanting it light up each individual column in order like the hand of clock moving around the face. When I applied this to the model as a whole it didn't come out right. However, if I put that effect on the strands instead it works perfectly. Of course, that only works because each circle has the same number of nodes. But, since that is what I have it works for me.
