 ## Effect of direction vector on scaling
+With scaling factor = 1
+
+Scaling|Direction Vector
+---|---
+all points move to the center|0, 0, 0
+no scaling|1, 1, 1
+scaling by a factor of 2|2, 2, 2
+scaling by a factor of 2 in the x-direction|2, 1, 1
+scaling by a factor of 2 in the y-direction|1, 2, 1
+scaling by a factor of 2 in the z-direction|1, 1, 2
+shrinking by a factor of 2|1/2, 1/2, 1/2
+shrinking by a factor of 3|1/3, 1/3, 1/3
+scaling by a factor of a, b, c in the x-, y- and z-direction|a, b, c
+
+Note that the scaling factor just multiplies all the scalings applied by the direction vector. Using a scaling factor of 2 and a direction vector of 1, 2, 3 is the same as using a scaling factor of 1 and a direction vector 2, 4, 8.
