I'm currently working on Voronoi polyhedra, and I already have software that generates all the vertices for me, but I haven't got any indexes to draw the polyhedra.

I know how to draw polygons and three-dimensional shapes using their vertices and indexes or repeating their vertices to form a list of triangles, but in this case I got a list of non repeating vertex.

There are 100 to 200 vertices, and it changes from file to file, I am searching for a library or a way to do the tessellation of the vertices and draw the polyhedra.

Just for illustration, I drew it using spheres placed on its vertices:
