How to sculpt an obituary shape onto the surface of my mesh - Questions - three.js forum

I created this working example where I can click on the surface of a mesh and it makes a small hill by changing the surface elevation. but instead, I would like to click and create any obituary shape onto the surface of my mesh like a circle, start or square etc. I have been trying to figure out a way to do this but I’m stuck and asking for help. This is my result so far, just hills.
