摘要

隨著科技的進步，虛擬機構的出現也越來越廣泛，虛擬機構可以讓人清楚地了解機構的構造、以及其運動方式。
本研究在於發展一個多軸虛擬機構系統，此系統主要是由兩部分組成:物件與座標。物件是由長方體、圓柱、圓球等三個幾何物件構成，藉由這三種幾何物件來建立出虛擬機構，系統內的座標與物件的數目可隨著使用者任意地增加，而物件必定隸屬於座標之下，座標之下必須有物件的存在，物件的運動是隨著座標的位置而改變，座標與座標之間可藉由輸入特定的函式來達到使用者的需求。之後，再以OpenGL來呈現出虛擬機構，建立完模型之後，再以分離軸定理在物間之間進行干涉判斷。

With the advances of technology, the virtual mechanism is more and more popular.
This paper develops a multi-axis virtual mechanism system, this system is combined by object and coordinate systems. This system provides three kind of objects include cuboid, cylinder, sphere. By using these objects to combine virtual mechanism. The number of the objects and coordinate systems can be increased by user. The object has to be subordinate to coordinate systems. Under the coordinate, there has to be an exist object. The motion of objects is effected by changing the parameter of coordinate. The function between coordinate systems can be inputted by user. Using OpenGL to show the virtual mechanism. After building the virtual mechanism, using the Separating Axis Theorem to know they had interference or not.
