3DモデルをCinema4Dからthree.jsにどのようにエクスポートしますか？

Question

Cinema 4Dでメッシュをモデル化した場合、three.js 3D JS Engineでどのようにエクスポートできますか？

色多角形選択の場合は、エクスポートすると便利です。

Answer 1

Cinema4D用の別のpythonスクリプトを書きました。

詳細はdisturb media blogとwikiです。参考のため

、私もここにソースをリストしています：

Export meshes the three.js 3D Engine by mr.doob's et al. 

More details on the engine here: 
https://github.com/mrdoob/three.js 

Currently supports UVs. If the model doesn't display correctly 
you might need to reverse some normals/do some cleanup. 
Also, if you use Selection Tags and basic ColorMaterials, 
the colours will be picked up as face colors. Call autoColor() on the 
model you use for this. 
The mesh transformations(position, rotation, scale) are saved 
and you can get them using: getPosition(), getRotation() and getScale() 
each returning a THREE.Vector3 

In short 
var myGeom = new myC4DGeom(); 
var myModel = new THREE.Mesh(myGeom, new THREE.MeshFaceMaterial()); 
//set transforms 
model.position = myGeom.getPosition() 
model.rotation = myGeom.getRotation() 
model.scale = myGeom.getScale() 
//set selection tags colours 
myGeom.autoColor()

Answer 2

Alirght、ここに試してみてください：

このプラグインはC4D R12では動作しません。 MaxonはPy4Dを吸収して以来、シンボルオブジェクトをc4dオブジェクトに吸収する選択をしました。私はあなたのcodeをフォークして、11.5のPy4DとR12の間の微妙な違いを解決しようとするためにちょっと調べました。

とにかく、ここではplugin cafe postを作成しました。ここで私は問題についてもう少しコメントしました。 awesomenessのための道を舗装してくれてありがとう！

Answer 3

別のオプションは、COLLADA/DAEまたはOBJとしてエクスポートし、COLLADALoaderまたはOBJLoaderを使用することです。

Answer 4

オブジェクト属性のエラーが発生した場合は、エクスポータスクリプト（c4d13 +）のGetAbsPosでGetPosコールを交換する必要があります。
