Key Points of the MIT License

  • Free for any use: commercial, open-source, internal, academic, and personal.
  • No usage limits: there are no call quotas, file-size caps, or watermark restrictions.
  • No API key required: install the package via NuGet and start using it immediately.
  • No registration: no account, no sign-in, no online activation.
  • Attribution: retain the copyright notice and the MIT License text in your distribution (see below).

Viewing the License in Your Installed Package

The LICENSE file is included in the NuGet package. You can locate it after installing by inspecting the package contents:

# View license via .NET CLI
dotnet nuget locals all --list

Or inspect the package directly:

# Download and extract the .nupkg to inspect its contents
nuget locals global-packages -list

No Commercial License Required

Unlike the commercial Aspose.3D product, this FOSS edition does not use the License or Metered API classes. These classes exist in the codebase but throw NotImplementedException — they are not functional in the open-source build. You do not need to call License.SetLicense() or configure any metered key.

// This is NOT required or meaningful in the FOSS edition:
// var license = new License();
// license.SetLicense("Aspose.3D.lic"); // throws NotImplementedException

// Simply install the package and use it directly:
using Aspose.ThreeD;
var scene = new Scene();
scene.Open("model.obj");

Redistribution and Bundling

If you redistribute the package as part of your own application or library:

  1. Include the original MIT License notice (the LICENSE file from the NuGet package is sufficient).
  2. You do not need to make your application open-source. The MIT License is permissive, not copyleft.
  3. You may modify the source code and distribute modified versions under the same MIT License.
