【摘要】 研究以离散的点构造三维物体的几何模型,以每个离散点为圆心,构造不同半径的圆,覆盖在三维几何模型表面,从而绘制该几何模型表示的几何物体的真实感图形.该方法与传统的多边形网格方法相比,具有存储量小、计算量小、易于实现的特点.更多还原

【Abstract】 A new method based on discrete points is proposed to model 3-D objects. Balls, which center at these discrete points and have different radiuses, were used to cover the surfaces of the objects to render the objects with realism. Compared with the classic mesh-based method, our method has the advantages of low storage, low calculation cost and implementation facilitation.更多还原
