Bezier Curve Modeled Phase Diagram

摘要

A new management method for storing and constructing phase diagram is proposed for purpose of reducing the amount of storage and improving the readability of the phase diagram. We name the new management method as Bezier curve modeled phase diagram (BCMPD). An entire phase diagram is consists of a set of cubic Bezier curves and straight lines under the BCMPD. Bezier curve based data structure is used for existing phase diagram storage is modeled by a cubic Bezier curve. The strategy of Bezier curve modeling each piece of curve within a phase diagram is discussed in detail. Experimental results proved the feasibility of the strategy. By using the proposed modeling strategy, users can construct a phase diagram more rapidly and precisely. Detail information within a phase diagram can be read easily by appointing a location in the drawing.
