Given the string str, produce a shorter random hash.
Different strings could produce the same hash, although

Draw a box with triangles in three.js
// the box geometry to initialise
var box=new THREE.Geometry();
// the trick to make all faces: vectors i, j and k have the coordinates of the triangles in the box
var i="011010111111100101000000001011110100".split('').map(c=>(c=='0')?0:1),

// this function multiplies each of the coordinates by a transformation matrix that turns them
// into an arbitrary box
