The Reuleaux tetrahedron is a three-dimensional geometric shape that is a type of convex hull formed around a tetrahedron. A Reuleaux tetrahedron is created by taking the convex hull of four points that are the vertices of a regular tetrahedron and then forming a shape by connecting arcs of circles centered at these vertices.
