【正文】 Curve 3D view, where: ?r1, r2 are the reference curves ?t1, t2 are the target curves ?P is a plane normal to the spine Planar view, where: ?Ir1: is the intersection between P and r1 ?Ir2: is the intersection between P and r2 ?It1: is the intersection between P and t1 ?It2: is the intersection between P and t2 8 曲面優(yōu)化工具命令 Wrap Curve 3D view, where: ?r1, r2 are the reference curves ?t1, t2 are the target curves ?P is a plane normal to the spine Planar view, where: ?Ir1: is the intersection between P and r1 ?Ir2: is the intersection between P and r2 ?It1: is the intersection between P and t1 ?It2: is the intersection between P and t2 曲線變形之原理： 首先，所有的變形都在脊線的法平面內(nèi)進(jìn)行。 ?關(guān)于投影方向 ：在下一頁有具體描述。 曲面優(yōu)化工具命令 Wrap Curve Ref1：固定，曲率 Ref3：固定 Ref2： 無目標(biāo)曲線 無目標(biāo)曲線 6 曲面優(yōu)化工具命令 Wrap Curve ?關(guān)于脊線 ：默認(rèn)第一條參考曲線即為脊線，但脊線若過短，如小于曲面的邊界框，則系統(tǒng)會自動延長脊線，相應(yīng)的其它配對曲線也會自動作延長。 曲面優(yōu)化工具命令 Wrap Curve 目標(biāo)曲線空出 連續(xù)性的選擇 右鍵彈出菜單 也可以在此勾選，效果一樣 5 Editing a Deformed Surface 曲線變形之修改編輯： 包括增加或移除參考曲線 目標(biāo)曲線配對，固定參考曲線，添加約束等。 ?具體操作 ：選擇參考曲線后，將鼠標(biāo)移至 “ ReferenceXXX” 字樣上，右鍵彈出下拉菜單，并選擇 “ Fixed reference curve” ，同時在對話框里將自動跳過目標(biāo)曲線的配對，直接換行進(jìn)入下一個配對的選擇，如下圖。 ?Reference and target curves can be multicells. Joined, blended, or matched curves, for example, can be used as reference or target curves. 參考曲線或目標(biāo)曲線可以是組合曲線。 ?You must always select successively a reference then a target curve to define a pair. You cannot select all reference curves, then al
