now it is a matter of something reasonable

Dear all,

I got a very simple case. Its only 2 Parameters to handle:

Parameter 1: the number of level.

Parameter 2: divide of opening on a floor.(increasing and progressive number. E.g. Floor1 with 4, Floor 2 with7, Floor3 with 12...etc)

The only things fixed are the 3 anchors.

Actually, this is very banal geometry, and it seems dosent make any sense to make it parametically. But once if we have to change it along a freeform tube, then it becames more complicate.

So, if anybody have idea how to approach it? I would very appreciate to ur opinion.

Hi Frank,

I did a bit of work for RWNB's tiling definitions that increased/decreased the number of divisions earlier in the year. Maybe you could adapt it to suit your needs:

Hi danny,

I tried to follow ur idea and it works really fine.

I also put a function in order to the get the proportion I need:

Now I also wanna take the last 2-3 level away(upper), so that it looks like, that the last level was divided into 3-4 a square piece. In this case, I tried to 'shift' the data in y-direction. But it seems wrong. Do u know what could be the problem?

ghx file are loaded.

Hi Frank,

Sorry about late reply, I've been away for the long weekend.

In this scenario it's easier to cull the branches that hold those rectangles at the end of the definition as it is to get the right numbers to generate only the required geometry. See attached

Hi Danny,

I think it was a wrong logic before what I have made.(I am mean do modify the Y input of rectangle...). By the way, to shift tree branches is clever!! Thanks lot.

At the beginn I intend to apply this scene on to a cylinder surface or a dome like the sketch before. In general we can manupulate it by using the skill like customization of item list...But it seems not the best way to controll the increasing and progressive grids...I guess...

Maybe there are some eleganter solution to apply this scene onto a dome?
