    • A clipping plane is formed between a projection center position and a projection plane such that the clipping plane is parallel to the projection plane. A three-dimensional line is subjected to clipping at the clipping plane. It is determined whether respective nodes constituting a three-dimensional line in a three-dimensional image to be projected onto the projection plane exist inside or outside a view volume, by comparing z-axis values of the nodes with a z-axis value of the clipping plane with respect to the projection center position. If the nodes of the three-dimensional line exist both inside and outside the view volume, a new three-dimensional line is constructed using nodes existing inside the view volume and intersections between the current three-dimensional line and the clipping plane, or using only the nodes existing inside the view volume.
    • 在投影中心位置和投影平面之间形成夹持平面,使得夹持平面平行于投影平面。 三维线在裁剪平面上进行裁剪。 通过将节点的z轴值与z轴的z轴值进行比较,确定构成投影到投影平面上的三维图像中的三维线的各个节点是否存在于视野体内或外部 相对于投影中心位置的剪切平面。 如果三维线的节点存在于视图体内部和外部,则使用存在于视图体内的节点和当前三维线和剪切平面之间的交点来构建新的三维线,或仅使用 节点存在于视图卷内。
