Ivy Generator與3ds max整合: 阿公的絲瓜園製作教學

菜瓜俗稱絲瓜, 菜瓜煮湯或是蛤蜊絲瓜都很好吃, 除了煮菜外, 菜瓜乾燥後還可做為海棉使用. 本教學我們將使用免費軟體---Ivy Generator(長春藤產生器), 這是由Thomas Luft先生寫的小軟體. 我們將利用Ivy generator模擬菜瓜在瓜棚上攀爬生長.

製作流程:
在3ds max 7當中

1. 導入Ivy Generator軟體附贈的牆模型, 這個牆可作為尺寸與旋轉角度的參考物體. (轉成obj格式時 模型會在x軸選轉90度)
2. 製作瓜棚與簡易版(proxy)的瓜棚模型讓菜瓜攀爬.
3. 將proxy模型輸出成3ds格式, 再以Deep exploration軟體將檔案轉成obj格式. (因為3dsmax內建的轉換會出現問題 各位可以自行嘗試)

在Ivy Generator當中:

4. 導入proxy瓜棚(obj格式)
5. 在瓜棚附近點擊一下, 點擊Grow開始生長菜瓜, 生長到適當時機再點擊Grow一次中只生長. 點擊birth使軟體產生菜瓜絲與菜瓜葉的3D模型. 輸出模型

回到3dsmax 7中

6. 導入模型. 調整尺寸與旋轉角度. 有需要的話用lowpoly方式製作菜瓜果實與菜瓜花.
7. 直接套用Xfrog tropical熱帶樹資料庫加入木瓜樹 增加整體效果.
8. 利用Finalrender MTD製做土地. 用免費的Darktree外掛套用dirt材質.

Ivy generator and 3dsmax integration, making of Luffa farm

Luffa vegetable know as Tsai-Quan(菜瓜) in Taiwan. Luffa is not only delicious, dry Luffa form Luffa sponge which is great for washing stuff (picture of dry Luffa click here). In this video tutorial we are going to use a free software---Ivy Generator, create by Thomas Luft, to simulate the rambling Luffa.

Still don't know what Luffa looks like? Try this link (Flickr)

Click HERE to the Ivy Generator download page.

Workflow:

In 3ds max 7

1. import wall obj file that ship with Ivy Generator, this wall is for size and rotational reference.

2. Create rack for the Luffa to ramble. Create proxy object for this rack.

3. export the proxy object as 3ds file. Import in Deep exploration and save as obj file.

4. Import the proxy rack object (in obj format)

5. Click on anywhere to start grow your Luffa. Hit "birth" to generate mesh for leaves and branch. Export the mesh.

Back in 3ds max 7

6. Import the mesh. Rescale or rotate if necessary. You can also making the Luffa fruits / flowers by polygonal modeling if you like to.

7. Adding other tropical plants like papaya by using Xfrog tropical library. (optional)

8. Generate ground plane with Finalrender MTD. Apply Darktree Dirt material.
