I have this larger face with the exact same 2 smaller copies above it. I have no idea how to make a smooth transition between them. Imagine one big mountain with 2 peaks. The tool I am searching for would extrude the bigger "parent" then move
upper vertices to their closest neighbors in the smaller copies by the same percentage. That would be repeated as many times as it takes to reach the shape of 2 copies. The higher the extruded level would be the closer vertices would be to both of these upper parts.
That would be of course linear but I would love to adjust that by a custom function.
This is my MODIFIED (for the sake of clarifying) proposition. Maybe there are other ways around it to get same result.
Okay, I can make this simpler.
I want to connect two small shapes to the big one.
Here is when I try the classic bridge edge loops.
The very origin of the problem is that I want to use a part of mandelbrot fractals as height map.
Which is impossible with orginal output and extremely hard (at least for me) to convert. So I tried by hand and this is the problem. Now as u can see, if this was somehow a height map it wouldn't have straight lines like in Aoradon solution. I might make edge loops in between though and scale them down. Subdivision surface mod would make it appear like a curve.
