3D sahnelerini GLTF 2.0 formatında C# 'dan tasarruf etmeden önce pbr olmayan malzemeleri dönüştürmeye özelleştirin

The Scene class of the Aspose.3D API represents a 3D scene. Developers can already build a 3D scene by adding various entities. GLTF 2.0 only supports PBR (Physically Based Rendering) materials, Aspose.3D API internally converts non-PBR materials into PBR materials before exporting into GLTF 2.0 (the materials in the scene will remain unchanged during the export), and the developers can provide custom convert function to override the default behavior.

Bu C# kod örneği, malzemeyi pbr malzemesine nasıl dönüştüreceğinizi gösterir ve daha sonra 3D görüntüsünü GLTF formatında C# 3D dosya manipülasyonu ve dönüştürme API ile kaydeder:

C#

 // initialize a new 3D scene

var s = new Scene();

var box = new Box();

s.RootNode.CreateChildNode("box1", box).Material = new PhongMaterial() {DiffuseColor = new Vector3(1, 0, 1)};

GLTFSaveOptions opt = new GLTFSaveOptions(FileFormat.GLTF2);

//Custom material converter to convert PhongMaterial to PbrMaterial

opt.MaterialConverter = (Material material) => {
    var pbr = PbrMaterial.FromMaterial(material);
    //customize your own PBR material here, you can get the original OBJ's material from the parameter mat.
    //to create a compatible material with obj2gltf, use following definition:
    pbr.MetallicFactor = 0;
    pbr.RoughnessFactor = 0.98;
    return pbr;
};

// save in GLTF 2.0 format

s.Save("test.gltf", opt);
