Description:: Unit vector, equal to direction from vector1 to vector2. In other words this command produces vectorNormalized between given 2 points.
Groups:: Uncategorised

Example 1:: [1,2,3] vectorFromTo [4,5,6]; //[0.57735,0.57735,0.57735] //is the same as vectorNormalized ([1,2,3] vectorDiff [4,5,6]); //[0.57735,0.57735,0.57735]
