C# .NET API to Create, Edit & Convert 3D Diagrams

Getting Started with Aspose.3D for .NET

The recommend way to install Aspose.3D for .NET is using NuGet. Please use the following command for a smooth installation.

dotnet add package Aspose.3D --version 23.2.0 

Generate & Save 3D Scene Programmatically via C# .NET API

Aspose.3D for .NET gives software developers the capability to generate new 3D scenes from the scratch and then save in any supported file format inside their own C# applications. The library allows loading existing 3D scenes, add asset information, changing plane orientation, accessing its properties, make changes to it and save it in various popular file formats such as PDF, HTML, and so on. The library also allows saving 3D document in different 3D formats, such as FBX, STL, DAE, RVM, OBJ, 3DS, DRC and so on.

var output = RunExamples.GetOutputFilePath("document.fbx");
// Create an object of the Scene class
Scene scene = new Scene();
// Save 3D scene document
scene.Save(output, FileFormat.FBX7500ASCII);

Convert 3D Document to Other File Formats via .NET

Aspose.3D for .NET allows computer programmers to open and convert 3D document in various supported file formats inside their own .NET applications. Using C# 3D document processing library you just need to load a 3D document in any supported file formats and call its save method with an appropriate FileFormat parameter. The library supports 3D scene conversion to PDF, HTML, FBX, DAE, 3DS, DRC, GLTF, OBJ, STL, RVM and many more.

// load the file to be converted
var scn = new Aspose.ThreeD.Scene(dir + "template.fbx");
// save in different formats
scn.Save(dir + "output.stl", Aspose.ThreeD.FileFormat.STLASCII);
scn.Save(dir + "output.obj", Aspose.ThreeD.FileFormat.WavefrontOBJ);

Create and Manage 3D Mesh via .NET API

Aspose.3D for .NET gives software developers the capability to work with 3D Meshes inside their own C# applications. The library allows generating a mesh of various 3D geometric shapes, defining control points and polygons in the simplest way to create meshes. The library also supports sharing mesh geometry data with multiple nodes which will help in better memory management. It support several important features such as merging and splitting meshes in 3D file, generating normal data for all meshes in a 3D file, encoding 3D mesh in the Google Draco file, converting mesh of a single 3D object in PLY file, convert mesh to triangle mesh and primitive shape to mesh and so on.

// Create a mesh of box(A box is composed by 6 planes)

Mesh box = (new Box()).ToMesh();
// Create a material element on this mesh
VertexElementMaterial mat = (VertexElementMaterial)box.CreateElement(VertexElementType.Material, MappingMode.Polygon, ReferenceMode.Index);
// And specify different material index for each plane
mat.Indices.AddRange(new int[] { 0, 1, 2, 3, 4, 5 });
// Now split it into 6 sub meshes, we specified 6 different materials on each plane, each plane will become a sub mesh.
// We used the CloneData policy, each plane will has the same control point information or control point-based vertex element information.
Mesh[] planes = PolygonModifier.SplitMesh(box, SplitMeshPolicy.CloneData);
mat.Indices.Clear();
mat.Indices.AddRange(new int[] { 0, 0, 0, 1, 1, 1 });
// Now split it into 2 sub meshes, first mesh will contains 0/1/2 planes, and second mesh will contains the 3/4/5th planes.
// We used the CompactData policy, each plane will has its own control point information or control point-based vertex element information.
planes = PolygonModifier.SplitMesh(box, SplitMeshPolicy.CompactData);

Insert & Edit Text in Visio Diagrams via .NET API

Aspose.3D for .NET allows software developers to working with Visio in different ways inside Visio Diagrams using .NET library. The C# library has include different features for handling text in shapes, such as inserting text shape, customize text shape in the Visio diagram, update the shape’s text, find and replace the shape’s text, apply Built-in or custom style-sheet to text, apply different style on the each text value of a shape, extract plain Text from the Visio diagram page and many more.

// Initialize scene object
Scene scene = new Scene();
// Get a child node object
Node cameraNode = scene.RootNode.CreateChildNode("camera", new Camera());
// Set camera node translation
cameraNode.Transform.Translation = new Vector3(100, 20, 0);
cameraNode.GetEntity().Target = scene.RootNode.CreateChildNode("target");
var output = RunExamples.GetOutputFilePath("camera-test.3ds");
scene.Save(output, FileFormat.Discreet3DS);
