Systems and methods of creating a 3 Dimensional (3D) model of an object suitable for 3D printing are described. A method comprises defining an initial cuboid of edge lengths Lx, Ly, Lz for creating the 3D model, wherein the initial cuboid implicitly includes inner cuboids such that starting from the initial cuboid each cuboid is recursively splitable into eight identical inner cuboids. The initial cuboid corresponds to the root node of an octree and the inner cuboids correspond to child nodes or leaves of the octree. Further, the method comprises iteratively, receiving an input from a user for modification of at least one inner cuboid, until the 3D model is created, wherein the modification includes marking the at least one inner cuboid as filled or empty. |
