The Optimization of DXF File Based on Greedy Algorithm and Its Dynamic Simulation Based on OpenGL

There are some problems about secondary development tools of AutoCAD. When reading and transforming DXF files, it comes to be unreasonable order and invisible graphs. This paper gives a Greedy Algorithm to optimize graphic trajectory, achieves its dynamic display by using OpenGL technology, and clearly reveals the order of graphic elements and the internal control points. It proves good application effect in the process and analysis of the instances.
