There was a problem hiding this comment.
This fixes seams on the mesh. The left mesh uses triangles where the tip vertex is duplicated for each triangle with a different normal (average of bottom normals). The right uses one (0,0,0) vertex at the tip:
You get the same seams with quads instead of triangles and even if you give the tip a finite radius, i.e. with a conical frustum. (?)

I want to remove the mesh generation code in Makie that's used for arrows and add replacements as GeometryPrimitives here. This is coupled with MakieOrg/Makie.jl#4925.
Currently this just adds
Cone()with the idea of simplifying the arrow components to full, closed meshes.
