I added a lot of planes depending on sphere´s vertices - so that each plane sits at a sphere´s vertices xyz position, I made a fiddle for that: https://jsfiddle.net/blackInk/v4tep8dc/5/

How can I make each plane rotate to look at sphere (face) normal direction based at given sphere´s vertex position?

Just a small addition: planeMesh.position.set( geometry.vertices[i].x, geometry.vertices[i].y, geometry.vertices[i].z );
could be shortened to planeMesh.position.copy( geometry.vertices[i] );
