Non-PBR to PBR Material Conversion

Introduction

Welcome to this step-by-step guide on using Aspose.3D for .NET to convert Non-PBR (Physically Based Rendering) to PBR materials. Aspose.3D is a powerful API that allows developers to work seamlessly with 3D file formats in their .NET applications.

Prerequisites

Before we dive into the tutorial, ensure you have the following prerequisites:

Aspose.3D for .NET: Make sure you have the Aspose.3D for .NET library installed. You can find the download link here .
Basic Understanding of C#: This tutorial assumes you have a fundamental understanding of C# programming.
IDE (Integrated Development Environment): Choose your preferred IDE for .NET development, such as Visual Studio.

Import Namespaces

In your C# code, start by importing the necessary namespaces:

using Aspose.ThreeD;
using Aspose.ThreeD.Entities;
using Aspose.ThreeD.Formats;
using Aspose.ThreeD.Shading;
using Aspose.ThreeD.Utilities;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

Step 1: Initialize a New 3D Scene

Begin by creating a new 3D scene using the following code:

// ExStart:Non_PBRtoPBRMaterial
// initialize a new 3D scene
var scene = new Scene();

Step 2: Create a 3D Object

Next, create a 3D object, for example, a box:

var box = new Box();
scene.RootNode.CreateChildNode("box1", box).Material = new PhongMaterial() { DiffuseColor = new Vector3(1, 0, 1) };

Step 3: Configure Material Conversion

Set up material conversion options for Non-PBR to PBR conversion:

GltfSaveOptions options = new GltfSaveOptions(FileFormat.GLTF2);
options.MaterialConverter = delegate (Material material)
{
    PhongMaterial phongMaterial = (PhongMaterial)material;
    return new PbrMaterial() { Albedo = new Vector3(phongMaterial.DiffuseColor.x, phongMaterial.DiffuseColor.y, phongMaterial.DiffuseColor.z) };
};

Step 4: Save in GLTF 2.0 Format

Save the converted scene in GLTF 2.0 format:

scene.Save("Your Output Directory" + "Non_PBRtoPBRMaterial_Out.gltf", options);
// ExEnd:Non_PBRtoPBRMaterial

Repeat these steps as needed for your specific use case, ensuring each detail is configured correctly.

Conclusion

Congratulations! You’ve successfully learned how to convert Non-PBR to PBR materials using Aspose.3D for .NET. This powerful tool opens up endless possibilities for 3D graphics manipulation in your .NET applications.
