我正在寻找一种在运行时将网格导出为stl / obj / fbx格式的方法,并将其保存在Android手机的本地文件中。
我该怎么做?如果存在,我愿意使用插件(免费/付费)。

这非常复杂,因为您必须阅读每种格式(stl / obj / fbx)的规范并理解它们才能自己制作。幸运的是,已经有许多插件可用于将Unity网格导出到stl,obj和fbx。
<强> FBX 强>:
UnityFBXExporter用于在运行时将Unity网格导出到fbx。
public GameObject objMeshToExport;
void Start()
{
string path = Path.Combine(Application.persistentDataPath, "data");
path = Path.Combine(path, "carmodel"+ ".fbx");
//Create Directory if it does not exist
if (!Directory.Exists(Path.GetDirectoryName(path)))
{
Directory.CreateDirectory(Path.GetDirectoryName(path));
}
FBXExporter.ExportGameObjToFBX(objMeshToExport, path, true, true);
}
<强> OBJ 强>:
对于obj,使用ObjExporter
。
public GameObject objMeshToExport;
void Start()
{
string path = Path.Combine(Application.persistentDataPath, "data");
path = Path.Combine(path, "carmodel" + ".obj");
//Create Directory if it does not exist
if (!Directory.Exists(Path.GetDirectoryName(path)))
{
Directory.CreateDirectory(Path.GetDirectoryName(path));
}
MeshFilter meshFilter = objMeshToExport.GetComponent<MeshFilter>();
ObjExporter.MeshToFile(meshFilter, path);
}
<强> STL 强>:
您可以将pb_Stl插件用于STL格式。
public GameObject objMeshToExport;
void Start()
{
string path = Path.Combine(Application.persistentDataPath, "data");
path = Path.Combine(path, "carmodel" + ".stl");
Mesh mesh = objMeshToExport.GetComponent<MeshFilter>().mesh;
//Create Directory if it does not exist
if (!Directory.Exists(Path.GetDirectoryName(path)))
{
Directory.CreateDirectory(Path.GetDirectoryName(path));
}
pb_Stl.WriteFile(path, mesh, FileType.Ascii);
//OR
pb_Stl_Exporter.Export(path, new GameObject[] { objMeshToExport }, FileType.Ascii);
}
