assimpWpfImporter ReadModel3D from stream - kreativasas - 11-28-2019
Hi,
just a question.
I read STL file with assimpwpf importer and everything is ok.
Now i stored stl file into a database in binary mode and i need to use wpf importer not from file but from a memory stream read from my database.
How i have to do? Is it possible?
Thanks

Instead of calling ReadModel3D method that takes fileName as parameter use the overload that accepts a stream:
Code:
/// <summary>
/// ReadModel3D method reads 3D models from stream and returns the 3D models as Model3DGroup or GeomentryModel3D.
/// When the model have additional textures, the resolveResourceFunc must be set a method that converts the resource name into a Stream.
/// </summary>
/// <param name="fileStream">file stream</param>
/// <param name="formatHint">file extension to serve as a hint to Assimp to choose which importer to use - for example ".dae"</param>
/// <param name="resolveResourceFunc">method that converts the resource name into Stream - used to read additional resources (materials and textures)</param>
/// <returns>WPF Model3D object</returns>
public Model3D ReadModel3D(Stream fileStream, string formatHint, Func<string, Stream> resolveResourceFunc = null)RE: assimpWpfImporter ReadModel3D from stream - kreativasas - 11-28-2019
Hi,
I tried to use overload but i received the error:
Assimp.AssimpException: 'Error importing file: Invalid parameters passed to ReadFileFromMemory()'
I simply create a memorystream from a bytes array and passed to read3dmodel overlay:
mystl=assimpWpfImporter.ReadModel3D(mystream, ".stl")
