this is my best guess, for each petal to create a quadmesh + a trimesh:
Hello
you don’t need plugins for this.
Bounding rectangle is replaced by
For the projection on sphere, uses Mobius transfomation
You have 2 inputs, the circle
you can choose to put the center on a polygon pike
the radius
Then play with T to deform or not the shapes
And for the mesh, it is easy, just uses the curves control points
You can then measure the bounding box to get the sphere radius. There is surely a simple equation to do that!
Radius = Circle Radius / Sin(T)
Center = Circle center + Circle Normal * Circle Radius / Tan(T)
To get the sphere you can use “Sphere Fit”

this is super helpful thank you so much, i wanted to try to put your mesh construction bit into my script so i could have both working, i had to figure out the points on mine and found its this (it took me longer than i would like to admit to figure this out lol)
but this happens? i dont even know where to start fixing this, do you have any ideas?
i havnt done much past adding your construct mesh bit at the end but i will add the file again just incase

I used “nice” ordered polygon for a reason.
If you want to use randomly ones, you’ll have to do a bit more work.
You can reorder them with the angles, or the side lengths …
Up to you.
