激光加工工艺软件的三维图形层次化拾取方法

Thehierarchical Selection Method of the Three-dimensional Graphics at Laser Processing Software

针对于激光三维图形加工的特殊性,提出一种对三维向量图形的层次化、多结构拾取方法。算法的核心思路是通过射线法对组成图元对象的各成员线簇分层拾取,从最小拾取单元的角度出发,以实现一种在激光三维加工应用中的从局部到整体的可控性三维拾取方法。本算法主要用Qt下的Opengl基本库函数实现,并在仿真中取得了较好的效果。

Directed against the particularity of three-dimensional graphics processing of laser, put forward a hierarchical and Structured selection method for 3 D Vector Graphics. The core idea of the method is to pick every lines of the meta-graphic-object layer by layer through ray method, make the minimum pick unit as starting point, to achieve a controllability picking method that from part to whole in 3D laser processing application. This method mainly use QT and OpenGL basic function library to realization and had good effect in the simulation.
