Abstract: In layered modeling for rapid prototyping of products, compromising slicing accuracy and time is a critical issue. Based on adaptive Layer Depth Normal Image (LDNI), this paper proposes an efficient algorithm to achieve this compromise for complex Constructive Solid Geometry (CSG) models. First, each primitive at the tree leaf is converted adaptively into a LDNI solid whose Boolean operation can be performed efficiently. Then, a layered model is constructed directly from the Booleaned LDNI solid since it is actually a set of layered and ordered point cloud. In addition to speed, efficient use of memory is also taken into account in design of the adaptive LDNI algorithm. The capability and efficiency of this slicing algorithm are demonstrated by examples.
