从命令行安装为 nuget install Aspose.3d 或通过 Visual Studio 的包管理器控制台使用 Install-Package Aspose.3D 安装。

或者，从 ZIP 文件中获取脱机 MSI 安装程序或 DLL 下载 .

C# USDZ 到 OBJ 转换的代码

// 在 Scene 对象中加载 USDZ 
var scene = new Aspose.ThreeD.Scene("template.usdz");
// 将 USDZ 保存为 OBJ 
scene.Save("output.obj", Aspose.ThreeD.FileFormat.WavefrontOBJ);

USDZ What is USDZ File Format?

A file with .usdz is an uncompressed and unencrypetd ZIP archive for the USD (Universal Scene Description) file format that contains and proxies for files of other formats (such as textures, and animations) embedded within the archive and runs them directly with the USD run-time without any need of unpacking. USDZ files are packages whose design is based on the new Ar-level abstraction of a package. Usdz was registered with IANA and has media type name of model and a subtype name of vnd.usd+zip and its details can be found as on IANA registration page.

OBJ What is OBJ File Format?

OBJ files are used by Wavefront’s Advanced Visualizer application to define and store the geometric objects. Backward and forward transmission of geometric data is made possible through OBJ files. Both polygonal geometry like points, lines, texture vertices, faces and free-form geometry (curves and surfaces) are supported by OBJ format. This format does not support animation or information related to light and position of scenes. An OBJ file is usually an end product of the 3D modeling process generated by a CAD (Computer Aided Design). The default order to store vertices is counter-clockwise avoiding explicit declaration of face normals. Though OBJ files declare scale information in a comment line yet no units have been declared for OBJ coordinates.
