Hi. I had this weird idea, i didn't know if it exist but i decided to give it a try. Basically, a way to 'connect' or 'join' two meshes with different topology in blender but with a 'transition' between the topology of each other. 

Basically, for example: Wanna connect a cube with a cilinder with a mesh in between that start with 4 vertex (one of the cube's faces) and get more complex as it reach the cilinder (ending with 32 vertices)?

Well that. I could create a couple of scripts for blender with the help of ChatGPT, and i think somebody can find it usefull.

How to use:

1)Select the 2 objects you wanna connect in blender and enter edit mode.

2) Select the edge loops you wanna connect.

3) Copy/Paste the desired script in the 'Text' panel of blender and click 'Play' button.

4) You should have now a new mesh generated that connect both objects transitioning their respective topologies.

5) you may wanna invert normals, since the generated mesh use to spawn with the inner faces outside. Simply enter the bridge mesh in edit mode -> select all faces -> recalculate outside.

Here is a YT video:

Hope somebody like it.
