將 Blender 建立的模型轉成 Rhinoceros 的 SubD
在 Blender 設計的模型若需要轉到 Rhinoceros 成可以繼續編輯的話,
使用一般網格肯定是不太可能,畢竟一般的網格實在太複雜也難以編輯。
然而在 Rhinoceros V6 之後的版本有 SubD 功能,
這樣的話對於模型的修改將會非常便利,而且還可以直接轉曲面。
前置作業:
-
如果是雕刻出來的高模,必須先 Retopology(重新拓普)成低模。
-
選取低模物件進入Blender編輯模式將模型需要銳利邊的部分以「標記銳利」(Mark Sharp)功能進行標記。

如果模型製作時僅使用「硬邊」(Crease)的方式製作硬邊,這也可以進編輯模式,先選取一條硬邊以「選取相似者」(Select Similar) 的 「Crease」將他們全選,接著再「標記銳利」(Mark Sharp)。
※如果有很多物件的硬邊需要標記,那就選取全部物件進編輯模式去進行會比較快。
※ Blender 的選取方式非常多樣化,可依需求以不同方式去進行選取,上述 「硬邊」只是其中一種方式,實際上 Blender 編輯模式(Edit Mode)下,頂點(Vertex)、邊線(Edge)、面 (Face)都有相應不同的選取功能。

最後匯出OBJ格式,注意「套用修改器」(Apply Modifiers)不要打鉤。

匯入犀牛後的作業:
首先必須是Rhinoceros V6 或以上的版本,因為需要使用到 SubD(ToSubD) 的功能。
V4或V5沒有 SubD 功能,轉入的 OBJ 只會變成一般網格。
- 1.將OBJ匯入 Rhinoceros 中,命列列輸入 ToSubD 功能(或由SubD 工具列選「轉換為SubD」)。

- 2.在命列列中 將「網格銳邊」變更為「是」,其餘選項依自己需求去變更或保留,然後按滑鼠右鍵確定即可。
