18% of the examples in your published example project throw exceptions when targeting .net core 3.1

I can’t get your example code for rendering a scene to a 2d image to work, it always throws exceptions (“Render3DModelImageFromCamera”.)

I tried pulling down your example project from GitHub - aspose-3d/Aspose.3D-for-.NET: Aspose.3D for .NET examples, plugins and showcases

When I compile the project targeting .net core 3.1, 13 of the 70 examples throw exceptions from inside the Aspose library. The failing methods are:

RenderSceneIntoCubemapwithsixfaces.Run: EXCEPTION: Object reference not set to an instance of an object.
Render3DModelImageFromCamera.Run: EXCEPTION: Object reference not set to an instance of an object.
CastAndReceiveShadow.Run: EXCEPTION: Object reference not set to an instance of an object.
ConvertPolygonsToTriangles.Run: EXCEPTION: Object reference not set to an instance of an object.
RenderPanaromaViewof3DScene.Run: EXCEPTION: Object reference not set to an instance of an object.
RenderFisheyeLensEffectof3DScene.Run: EXCEPTION: Object reference not set to an instance of an object.
ApplyVisualEffects.Run: EXCEPTION: Object reference not set to an instance of an object.
CaptureViewPort.Run: EXCEPTION: Object reference not set to an instance of an object.
DecodeMesh.Run: EXCEPTION: Object reference not set to an instance of an object.
EncodeMesh.Run: EXCEPTION: Object reference not set to an instance of an object.
EncodeMeshToPly.Run: EXCEPTION: Object reference not set to an instance of an object.
ExportToPlyAsPointCloud.Run: EXCEPTION: Object reference not set to an instance of an object.
Export3DSceneAsPointCloud.Run: EXCEPTION: Object reference not set to an instance of an object.

I was under the impression that you supported .net core. Is this not the case?

In reading other posts in this forum, I saw that it appears Rendering is not supported in .net Core. Is there any plan to support this? Also, what functionality of Aspose.3d is supported running as .net core on non-windows OS’s?

@OBCad,

Can you please share source files along with sample project so that we may further investigate to help you out.

GitHub - aspose-3d/Aspose.3D-for-.NET: Aspose.3D for .NET examples, plugins and showcases

Just change the target in your project definition to dotnetcore, and try and build and run the samples.
