“…The first category includes the semi free-form features. They correspond to free-form surfaces obtained by classical rules such as loft/sweep operations, interpolation rules or specific relationships directly expressed between the control points [1], [2], [12], [14], [15], [16], [13], [6]. Users often have few possibilities to control the resulting shapes.…”

“…根据曲面特征的自由度和曲面形状的表示精度, 本文将曲面特征分成两类: 半自由曲面特征、完 全自由曲面特征. 其中, 半自由曲面特征的几何形状具有一定的共性: 都可通过特征线精确表示曲面 的内部形状, 与规则形状特征类似, 已有相关文献介绍 [14,15] , 如某脊特征、凸特征等, 如图 5(a) 和 (b) 所示; 而完全自由曲面特征难以直接通过特征线精确表示曲面内部所有位置的形状, 在完全自由曲面 特征表示上, 需要结合基本形状 (设置语义参数) 和细节形状 (设置曲面控制点和权因子等) 表示, 如 图 5(c) 所示. 由此, 将曲面特征的参数化分类为: 半自由曲面特征和完全自由曲面特征.…”
