<p><P>PROBLEM TO BE SOLVED: To simulate the milling with a high degree of accuracy, in a time-efficient manner. <P>SOLUTION: A method performed on a processor is provided for simulating the milling of an object by moving a shape along a path intersecting the object. A composite adaptively-sampled distance field (ADF) which includes a set of cells is generated to represent the object. Each cell in the composite ADF includes a set of distance fields and a procedural reconstruction method for reconstructing the object within the cell. The shape is represented by a shape distance field. The path is represented by a parametric function. A swept volume distance field is defined in a continuous manner, to represent a swept volume generated, by moving the shape along the path, according to a swept volume reconstruction method which reconstructs the swept volume distance field at a sample point. The composite ADF is edited to incorporate the swept volume distance field into the composite ADF to simulate the milling. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
