This paper describes a method to accelerate the generation of shape primitives for N-dimensional images N X . These shape primitives can be used in conditions for topology preserving erosion or skeletonization in Ndimensional images. The method is based on the possibility to describe primitives for intrinsic dimensions 1N N= −% by quadratic equations of the form ( ) 1 2 0 n N N n x n n n x a x b x = − = = +∑ .
