تخصيص تحويل مواد غير PBR إلى PBR قبل توفير 3D مشاهد إلى تنسيق GLTF 2.0

Non-PBR إلى PBateraterateron

This code example demonstrates how to convert material to PBR material, and then saves 3D scene in the GLTF format:

// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
/* initialize a new 3D scene */
Scene s = new Scene();
Box box = new Box();
PhongMaterial mat = new PhongMaterial();
mat.setDiffuseColor(new Vector3(1, 0, 1));
s.getRootNode().createChildNode("box1", box).setMaterial(mat);
GLTFSaveOptions opt = new GLTFSaveOptions(FileFormat.GLTF2);
//Custom material converter to convert PhongMaterial to PbrMaterial
opt.setMaterialConverter(new MaterialConverter() {
@Override
public Material call(Material material) {
PhongMaterial m = (PhongMaterial) material;
PbrMaterial ret = new PbrMaterial();
ret.setAlbedo(m.getDiffuseColor());
return ret;
}
});
// save in GLTF 2.0 format
s.save(MyDir + "Non_PBRtoPBRMaterial_Out.gltf", opt);
