Ange 3D Filspararalternativ

3D Filspararalternativ

Det finns flera Scene.save metod överbelastningar som accepterar en SaveOptions instans. Detta bör vara en instans av en klass som härrör från SparaOptions-klassen. Varje spara format har en motsvarande klass som innehar spara alternativ för att spara formatet, till exempel det finns ColladaSaveOptions för FileFormat. COLLADA spara format.

Användning av Collada Spara inställningar

Koden nedan visar hur sparalternativ ska ställas innan en 3D-fil sparas i Collada-format.

// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
ColladaSaveOptions saveColladaopts = new ColladaSaveOptions();
// Generates indented XML document
saveColladaopts.setIndented(true);
// The style of node transformation
saveColladaopts.setTransformStyle(ColladaTransformStyle.MATRIX);
// Configure the lookup paths to allow importer to find external dependencies.
saveColladaopts.getLookupPaths().add(MyDir);

// The start base for generating new name for duplicated names.
saveOpts.setDuplicatedNameCounterBase(2);
// The format of the duplicated counter.
saveOpts.setDuplicatedNameCounterFormat("NameFormat");
// The separator between object's name and the duplicated counter.
saveOpts.setDuplicatedNameSeparator("Separator");
// Allows to export cameras
saveOpts.setExportCamera(true);
// Allows to export light
saveOpts.setExportLight(true);
// Flip the coordinate system
saveOpts.setFlipCoordinateSystem(true);
// Prefer to use gamma-corrected color if a 3ds file provides both original color and gamma-corrected color.
saveOpts.setGammaCorrectedColor(true);
// Use high-precise color which each color channel will use 32bit float.
saveOpts.setHighPreciseColor(true);

// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize Scene object
Scene scene = new Scene();
// Create a child node

// Set glTF saving options. The code example embeds all assets into the target file usually a glTF file comes with some dependencies, a bin file for model's vertex/indices, two .glsl files for vertex/fragment shaders
// Use opt.EmbedAssets to tells the Aspose.3D API to export scene and embed the dependencies inside the target file.
GLTFSaveOptions opt = new GLTFSaveOptions(FileContentType.ASCII);
opt.setEmbedAssets(true);
// Use KHR_materials_common extension to define the material, thus no GLSL files are generated.
opt.setUseCommonMaterials(true);
// Customize the name of the buffer file which defines model
opt.setBufferFile("mybuf.bin");
// Save glTF file
scene.save(MyDir + "glTFSaveOptions_out.gltf", opt);

// Use setter to change this configuration.
opt.setPrettyPrint(true);
// Save 3D Scene
scene.save(RunExamples.getDataDir() + "prettyPrintInGltfSaveOption.gltf", opt);

Spara beroenden för en 3D i det verkliga filsystemet

Utvecklare kan behöva spara alla beroenden av 3D i det riktiga filsystemet. De kan definiera sökvägen för en lokal katalog, spara i MemoryFileSystem- objektet eller helt enkelt förkasta beroenden. Egenskapen FileSystem läggs till i alla spara alternativklasser.

Kasta sparande av materialfiler

// The code example uses the DummyFileSystem, so the material files are not created.
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize Scene object
Scene scene = new Scene();
// Create a child node
scene.getRootNode().createChildNode("sphere", new Sphere()).setMaterial(new PhongMaterial());
// Set saving options
ObjSaveOptions opt = new ObjSaveOptions();
opt.setFileSystem(new DummyFileSystem());
// Save 3D scene
scene.save(MyDir + "DiscardSavingMaterial_out.obj", opt);

Spara beroende i lokalkatalog

// The code example uses the LocalFileSystem class to save dependencies to the local directory.
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize Scene object
Scene scene = new Scene();
// Create a child node
scene.getRootNode().createChildNode("sphere", new Sphere()).setMaterial(new PhongMaterial());
// Set saving options
ObjSaveOptions opt = new ObjSaveOptions();
opt.setFileSystem(new LocalFileSystem(MyDir));
// Save 3D scene
scene.save(MyDir + "SavingDependenciesInLocalDirectory_out.obj", opt);

Spara beroende i MemoryFileSystem Instans

// The code example uses the MemoryFileSystem to intercepts the dependencies writing.
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize Scene object
Scene scene = new Scene();
// Create a child node
scene.getRootNode().createChildNode("sphere", new Sphere()).setMaterial(new PhongMaterial());
// Set saving options
ObjSaveOptions opt = new ObjSaveOptions();
MemoryFileSystem mfs = new MemoryFileSystem();
opt.setFileSystem(mfs);
// Save 3D scene
scene.save(MyDir + "SavingDependenciesInMemoryFileSystem_out.obj", opt);
// Get the test.mtl file content
byte[] mtl = mfs.getFileContent(MyDir + "SavingDependenciesInMemoryFileSystem_out.mtl");
Files.write(Paths.get(MyDir, "Material.mtl"), mtl);

Användning av Google Draco (.DRC) Spara inställningar

Koden nedan visar hur sparalternativ ska ställas innan en 3D-modell sparas till DRC-formatet.

String MyDir = RunExamples.getDataDir();
// Initialize Scene object
Scene scene = new Scene();
// Create a child node
scene.getRootNode().createChildNode("sphere", new Sphere());
// Initialize .DRC saving options.
DracoSaveOptions opts = new DracoSaveOptions();
// Quantization bits for position
opts.setPositionBits(14);
// Quantization bits for texture coordinate
opts.setTextureCoordinateBits(8);
// Quantization bits for vertex color
opts.setColorBits(10);
// Quantization bits for normal vectors
opts.setNormalBits(7);
// Set compression level
opts.setCompressionLevel(DracoCompressionLevel.OPTIMAL);
// Save Google Draco (.drc) file
scene.save(MyDir + "DRCSaveOptions_out.drc", opts);

Användning av RVM Spara inställningar

Koden nedan visar hur sparalternativ ska ställas innan en 3D-modell sparas till RVM-formatet.

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
String dataDir = RunExamples.getDataDir();
Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("Box", new Box());
node.setProperty("rvm:Refno", "=3462123");
node.setProperty("rvm:Description", "This is the description of the box");
//The RVM attribute's prefix is rvm:, all properties that starts with rvm: will be exported to .att file(the prefix will be removed)
RvmSaveOptions opt = new RvmSaveOptions();
opt.setAttributePrefix( "rvm:");
opt.setExportAttributes(true);
scene.save(dataDir + "test.rvm", opt);
