Transforming Node by Quaternion

Introduction

Welcome to a step-by-step guide on transforming a node by quaternion in 3D scenes using Aspose.3D for .NET. In this tutorial, we’ll explore the powerful capabilities of Aspose.3D for .NET and walk through the process of adding transformations to a 3D node using quaternions.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites in place:

Aspose.3D for .NET: Ensure you have the Aspose.3D library installed. You can download it from the release page .
Development Environment: Set up your .NET development environment with the necessary tools and configurations.
Basic Understanding of 3D Concepts: Familiarity with 3D graphics and concepts will be helpful.

Import Namespaces

In your .NET project, include the required namespaces for Aspose.3D:

using System;
using System.Collections.Generic;
using System.IO;
using Aspose.ThreeD;
using Aspose.ThreeD.Entities;
using Aspose.ThreeD.Utilities;

Step 1: Initialize the Scene Object

// ExStart:AddTransformationToNodeByQuaternion            
// Initialize scene object
Scene scene = new Scene();

Step 2: Initialize Node Class Object

// Initialize Node class object
Node cubeNode = new Node("cube");

Step 3: Create Mesh using Polygon Builder

// Call Common class create mesh using polygon builder method to set mesh instance 
Mesh mesh = Common.CreateMeshUsingPolygonBuilder();

Step 4: Point Node to the Mesh Geometry

// Point node to the Mesh geometry
cubeNode.Entity = mesh;

Step 5: Set Rotation using Quaternion

// Set rotation
cubeNode.Transform.Rotation = Quaternion.FromRotation(new Vector3(0, 1, 0), new Vector3(0.3, 0.5, 0.1));

Step 6: Set Translation

// Set translation
cubeNode.Transform.Translation = new Vector3(0, 0, 20);

Step 7: Add Cube to the Scene

// Add cube to the scene
scene.RootNode.ChildNodes.Add(cubeNode);

Step 8: Save 3D Scene

// The path to the documents directory.
var output = "Your Output Directory" + "TransformationToNode.fbx";

// Save 3D scene in the supported file formats
scene.Save(output, FileFormat.FBX7500ASCII);
// ExEnd:AddTransformationToNodeByQuaternion
Console.WriteLine("\nTransformation added successfully to node.\nFile saved at " + output);

Conclusion

Congratulations! You’ve successfully learned how to transform a node by quaternion in 3D scenes using Aspose.3D for .NET. Explore more features and possibilities by referring to the documentation .
