I am currently looking to create a backplane behind my meshes. The backplane would follow the shape of meshes at the extremity of group.
Below a example of what I try to do. Green line (border of a plane) could be more or less adjusted with the shapes (red) depending of constant for example.
Any idea how I could do that ?
Minkowski addition - Wikipedia
There’s a codesandbox example of using the library. Perhaps try a quick code sandbox with your shapes and calling the Minkownski class class in the library
Hope this helps or try asking Chat GPT
The red part need to be created and does not exist initially.
Let me decompose my goal on only 1 mesh (If can do it on 1 mesh I would be able to do it on all of my scene meshes then):
1: This is what I am currently able to create. 1 SVG extruded that generate the black shape.
Then on the botton of bouding box I create a plane with same dimension and small height.
2: This is what I am trying to achieve.
Same extruded SVG but the background outline the black shape. Complexity comes because balck SVG have holes.
