Setting Three-Dimensional Properties in 3D Scenes

Introduction

Creating captivating three-dimensional scenes often requires the ability to manipulate various properties, adding depth and realism to your projects. Aspose.3D for .NET provides a powerful toolset to achieve this, allowing you to set and modify three-dimensional properties within your 3D scenes effortlessly. In this tutorial, we’ll explore the process step by step, enhancing your understanding of how to leverage Aspose.3D for .NET effectively.

Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites:

Aspose.3D for .NET: Ensure you have the library installed in your .NET project. You can download it here .
Document Directory: Create a directory to store your 3D documents.

Now that you have the essentials in place, let’s explore the process of setting three-dimensional properties in 3D scenes using Aspose.3D for .NET.

Import Namespaces

To get started, import the necessary namespaces into your project. These namespaces provide the classes and methods required for working with three-dimensional properties in Aspose.3D for .NET.

using Aspose.ThreeD;
using Aspose.ThreeD.Shading;
using Aspose.ThreeD.Utilities;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Step 1: Load 3D Scene

Begin by loading a 3D scene. In this example, we use an FBX file with an embedded texture.

//ExStart: Load3DScene
string dataDir = "Your Document Directory";
Scene scene = new Scene(dataDir + "EmbeddedTexture.fbx");
//ExEnd: Load3DScene

Step 2: Access Material Properties

Access the material properties of the loaded 3D scene to manipulate its characteristics.

//ExStart: AccessMaterialProperties
Material material = scene.RootNode.ChildNodes[0].Material;
PropertyCollection props = material.Properties;
//ExEnd: AccessMaterialProperties

Step 3: List All Properties

List all the properties of the material using a foreach loop or an ordinal for loop.

//ExStart: ListAllProperties
foreach (var prop in props)
{
    Console.WriteLine("{0} = {1}", prop.Name, prop.Value);
}

//or using ordinal for loop
for (int i = 0; i < props.Count; i++)
{
    var prop = props[i];
    Console.WriteLine("{0} = {1}", prop.Name, prop.Value);
}
//ExEnd: ListAllProperties

Step 4: Get and Modify Property by Name

Retrieve and modify a specific property by its name.

//ExStart: GetModifyPropertyByName
var diffuse = props["Diffuse"];
Console.WriteLine(diffuse);

//modify property value by name
props["Diffuse"] = new Vector3(1, 0, 1);
//ExEnd: GetModifyPropertyByName

Step 5: Get Property Instance by Name

Retrieve a property instance by its name for further manipulation.

//ExStart: GetPropertyInstanceByName
Property pdiffuse = props.FindProperty("Diffuse");
Console.WriteLine(pdiffuse);
//ExEnd: GetPropertyInstanceByName

Step 6: Traverse Property’s Properties

Since Property is inherited from A3DObject, you can traverse the properties of a property.

//ExStart: TraversePropertyProperties
Console.WriteLine("Property flags = {0}", pdiffuse.GetProperty("flags"));

//and some properties that only defined in FBX file:
Console.WriteLine("Label = {0}", pdiffuse.GetProperty("label"));
Console.WriteLine("Type Name = {0}", pdiffuse.GetProperty("typeName"));

//traversal on property's property is possible
foreach (var pp in pdiffuse.Properties)
{
    Console.WriteLine("Diffuse.{0} = {1}", pp.Name, pp.Value);
}
//ExEnd: TraversePropertyProperties

Conclusion

Congratulations! You’ve now mastered the art of setting three-dimensional properties in 3D scenes using Aspose.3D for .NET. Experiment with different properties and values to bring your 3D projects to life.
