Remove face from mesh

[lofty bear]

Good afternoon, how is it possible to remove one of the face mesh if the mesh consists of convexgeometry

[dawn ridge]

have a look at the geometry object by printing it out. there are two ways how you can determine faces. a: you double the verts for every triangle. b: you have a array of vertices for each face

so you either have to delete the verts in the specific bufferattribute , or you need to delete the elements from the faces array of the specific bufferattribute that point to the vertex array

if you want to find the specific face in the list, you can use raycast and nearest neighbor search, or quad tree to find that face(above 1000 verts! below use brute force) .

keep in mind that you cant add verts to an existing mesh
