Public API Changes in Aspose.3D 16.11.0

Contents Summary

Adds AddEntity Method in the Aspose.ThreeD.Node Class

A shortcut way for adding an entity to a node.

Add an Entity to a Node

 // initialize a Scene class object

Scene scene = new Scene();

// create a node

Node sphere = scene.RootNode.CreateChildNode("sphere");

// the old way to add an entity in a node

sphere.Entities.Add(new Sphere());

//the new way to add an entity in a node

sphere.AddEntity(new Sphere());

Import and Export of glTF Files

Using the recent version (16.11.0) or higher, developers can import and export glTF files to/from other supported 3D files.

Adds Aspose.ThreeD.Formats.GLTFLoadOptions Class

We have added GLTFLoadOptions class. It helps in importing glTF files into Aspose.3D API.

Flip the V/T Texture Coordinate

 Scene scene = new Scene();

GLTFLoadOptions loadOpt = new GLTFLoadOptions();

//The default value is true, usually we don't need to change it.

//Aspose.3D will automatically flip the V/T texture coordinate during load and save.

//to make sure it's compatible with Aspose.3D

loadOpt.FlipTexCoordV = true;

scene.Open("Duck.gltf", loadOpt);

Adds Aspose.ThreeD.Formats.GLTFSaveOptions Class

We have added GLTFSaveOptions class. It defines settings on saving a glTF file.

Embed Dependencies Inside the Output glTF File

 // the code example creates a glTF file that has a sphere, and embed 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 to export scene and embed the dependencies inside the target file.

Scene scene = new Scene();

scene.RootNode.CreateChildNode("sphere", new Sphere());

GLTFSaveOptions opt = new GLTFSaveOptions(FileContentType.ASCII);

opt.EmbedAssets = true;

scene.Save("d:\\test.gltf", opt);

Use KHR_materials_common Extensions to Define the Materials

 // the code example creates a glTF file that has a sphere, and use KHR_materials_common extensions to define the materials

// thus no GLSL files are generated.

Scene scene = new Scene();

scene.RootNode.CreateChildNode("sphere", new Sphere());

GLTFSaveOptions opt = new GLTFSaveOptions(FileContentType.ASCII);

opt.UseCommonMaterials = true;

scene.Save("d:\\test.gltf", opt);

Customize the Filename of Buffer File

 // the code example creates a glTF file that has a sphere, and the buffer file that defined the model to customize the filename

Scene scene = new Scene();

scene.RootNode.CreateChildNode("sphere", new Sphere());

GLTFSaveOptions opt = new GLTFSaveOptions(FileContentType.ASCII);

opt.BufferFile = "mybuf.bin";

scene.Save("d:\\test.gltf", opt);

Creates a Binary glTF File using KHR_binary_glTF Extension

 // the code example creates a binary glTF file using KHR_binary_glTF extension

Scene scene = new Scene();

// create a child node

scene.RootNode.CreateChildNode("sphere", new Sphere());

// save 3D file

scene.Save("d:\\test.glb", FileFormat.GLTF_Binary);

Creates a Binary glTF File using KHR_binary_glTF Extension along with Saving Options

 // the code example creates a binary glTF file using KHR_binary_glTF extension but allow you to configure the save options

Scene scene = new Scene();

// create a child node

scene.RootNode.CreateChildNode("sphere", new Sphere());

// use saving options

GLTFSaveOptions opt = new GLTFSaveOptions(FileContentType.Binary);

opt.UseCommonMaterials = true;

// save 3D file

scene.Save("d:\\test.glb", opt);

Adds glTF Format Entry in the Aspose.ThreeD.FileFormat Class

We have added a GLTF and GLTF_Binary format entries for loading and saving purposes.

Adds an Extension property in the Aspose.ThreeD.FileFormatType Class

We have added an Extension property in the FileFormatType class to get the extension name of the file format.

Write Dependencies in the Real File System

Using the recent version (16.11.0) or higher, developers can save all 3D scene dependencies in the real file system. Developers may define the path of a local directory, save in the MemoryFileSystem object or simply discard dependencies. The FileSystem property is added in the all save option classes.

Adds Aspose.ThreeD.Utilities.DummyFileSystem Class

Discard Saving the Material Files

 // the code example uses the DummyFileSystem, so the material files are not created.

Scene scene = new Scene();

// create a child node

scene.RootNode.CreateChildNode("sphere", new Sphere()).Material = new PhongMaterial();

// set saving options

ObjSaveOptions opt = new ObjSaveOptions();

opt.FileSystem = new DummyFileSystem();

// save 3D scene

scene.Save("d:\\test.obj", opt);

Adds Aspose.ThreeD.Utilities.LocalFileSystem Class

Save Dependencies in the Local Directory

 // the code example uses the LocalFileSystem class to save dependencies to the local directory.

Scene scene = new Scene();

// create a child node

scene.RootNode.CreateChildNode("sphere", new Sphere()).Material = new PhongMaterial();

// set saving options

ObjSaveOptions opt = new ObjSaveOptions();

opt.FileSystem = new LocalFileSystem("E:\\");

// save 3D scene

scene.Save("d:\\test.obj", opt);

Adds Aspose.ThreeD.Utilities.MemoryFileSystem Class

Save Dependencies in the MemoryFileSystem Object

 // the code example uses the MemoryFileSystem to intercepts the dependencies writing.

Scene scene = new Scene();

// create a child node

scene.RootNode.CreateChildNode("sphere", new Sphere()).Material = new PhongMaterial();

// set saving options

ObjSaveOptions opt = new ObjSaveOptions();

MemoryFileSystem mfs = new MemoryFileSystem();

opt.FileSystem = mfs;

// save 3D scene

scene.Save("d:\\test.obj", opt);

//get the test.mtl file content

byte[] mtl = mfs.GetFileContent("test.mtl");

File.WriteAllBytes("material.mtl", mtl);

Adds FileSystem property in the Aspose.ThreeD.Formats.IOConfig Class

We have added a FileSystem property in the IOConfig class to write dependencies.

Adds a FileSystem property

 Aspose.ThreeD.Utilities.FileSystem FileSystem{ get;set;}
