摘要: 针对三维重建后的表面模型的任意剖切,首先通过对象的序列轮廓去掉图像背景,然后计算其模型及图像空间中包围盒和剖切平面的交面,利用向量叠加原理及立方体线性插值方法快速提取交面图像,经Alpha测试后映射到模型空间中相应切面上。实验表明,该方法在克服面绘制技术不能体现内部数据缺点的同时,有效地提高了模型任意剖切时剖面纹理绘制速度。

Abstract: Targeted to arbitrary cutting of surface model by 3D reconstruction, this paper first removed the object' s background by its contour data, and then computed the intersecting polygon of cutting plane and bounding box of the model in model and image spaces

Key words: Arbitrary cutting,Texture mapping, 3D surface reconstruction, Surface rendering
