Description

クリッピング面１１２の生成について詳述すると、上述したように、パラメータｈにより代表点Ｐが定められると、代表点Ｐと２つの端点Ｐ１，Ｐ２とに基づくスプライン補間演算により、背骨のような基本線として曲線１０４が生成される。端点Ｐ１は上述した点ａ１２であり、端点Ｐ２は上述した点ａ３４である。曲線１０４は代表点Ｐを挟んでＺ方向両側において線対称の形状を有している。但し、図６においてはクリッピング面１１２の形状をより分かり易く表現方法が採用されている。
The generation of the clipping plane 112 will be described in detail. As described above, when the representative point P is determined by the parameter h, a basic line like a backbone is obtained by spline interpolation based on the representative point P and the two end points P1 and P2. As a result, a curve 104 is generated. The end point P1 is the point a12 described above, and the end point P2 is the point a34 described above. The curve 104 has a line-symmetric shape on both sides in the Z direction across the representative point P. However, in FIG. 6, a method of expressing the shape of the clipping plane 112 more easily is adopted.
