Adds MaterialConverter Member to Aspose.ThreeD.Formats.GLTFSaveOptions Class

GLTF 2.0 only supports PBR materials, Aspose.3D will internally convert 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 user can provide custom convert function to override the default behavior.

This code example demonstrates how to convert material to PBR material, and then saving 3D scene to GLTF 2.0 format:

.NET, C#

 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 = delegate(Material material)


    PhongMaterial m = (PhongMaterial) material;

    return new PbrMaterial() {Albedo = new Vector3(m.DiffuseColor.x, m.DiffuseColor.y, m.DiffuseColor.z)};


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