摘　　要：将科学计算可视化技术应用于原木CT图像的3D重建中,实现了一个具有用户交互切削、虚拟加工功能的系统Wood3D。使用该系统可以在计算机屏幕上虚拟切割出复杂形状的木产品,并通过阈值选取,实现对原木中缺陷图像的分割。通过进一步对缺陷3D立体化显示,使用户对缺陷的大小和分布有最直观的了解,进而选择最佳的切割方案。Visualization of scientific compute now is practically used in the 3D reconstruction of log’s CT image. In this paper, a wood 3D system, which has multiple functions, like user-interactive cutting, virtual manufacture and several others, was implemented. This system can virtually cut out wooden products with complicated shapes in the computer screen, and select them by conditions that were used to divide the flaw of the log images. Moreover, according to more detailed 3D visualization of the flaws, users can have visually understanding of the size and the distribution of flaws. Thus, the best cutting scheme can be chosen.
