Instance of generatemotiv() function appearing in Algorithm 1 in the simplified 2D case. The original leit–motiv (dashed blue line), centered around its pivotal point (xo,yo) generates at the successive iteration four leit-motivs in the respective quadrants. For ease of presentation the transformation is depicted in the 2D case, embedded in a square (thin black line). The 3D case is a straightforward extension of this concept
