Research and Realization of the Algorithm for Rapid Display in 3-Axis NC Milling Simulation System
Display speed is one of the important factors in NC simulation system. It is very difficult to meet the requirement of the continuous animation by full-redraw mechanism. An algorithm for part-redraw mechanism, based on OpenGL stencil buffer and the display area defined twice, is delivered. When the algorithm is put into use in NC simulation system, the top surface of the workpiece can be represented as a set of triangle grids, especially, the number of the triangle grids exceeds millions of magnitude, the display speed is increased from (2.109±0.10)f/s to (57.826±1.00)f/s.
