Controlling Center in Linear Extrusion with Aspose.3D for Java

Introduction

In the world of 3D graphics and Java programming, controlling the center in linear extrusion plays a crucial role in achieving the desired effects in your projects. Aspose.3D for Java provides a powerful toolkit to handle such tasks seamlessly. In this tutorial, we’ll dive into the process of controlling the center in linear extrusion using Aspose.3D for Java, breaking down each step to ensure a smooth and comprehensive understanding.

Prerequisites

Before we embark on this tutorial journey, make sure you have the following prerequisites in place:

Java Development Environment: Ensure that you have a Java development environment set up on your machine.
Aspose.3D for Java: Download and install the Aspose.3D library. You can find the library and its documentation here .
Document Directory: Create a directory to store your Java documents. Let’s call it “Your Document Directory.”

Import Packages

In your Java development environment, import the necessary packages for Aspose.3D. This ensures that your code has access to the functionalities provided by the library.

import com.aspose.threed.*;


import java.io.IOException;

Step 1: Set Up the Base Profile

Initialize the base profile to be extruded. In this example, we’ll use a rectangle shape with a rounding radius of 0.3.

// The path to the documents directory.
String MyDir = "Your Document Directory";
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);

Step 2: Create a 3D Scene

Build the foundation of your 3D world by creating a scene.

Scene scene = new Scene();

Step 3: Create Left and Right Nodes

Establish left and right nodes within your scene. These nodes serve as the canvas for your 3D objects.

Node left = scene.getRootNode().createChildNode();
Node right = scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new Vector3(5, 0, 0));

Step 4: Linear Extrusion with Center Property

Perform linear extrusion on the left node without centering, and set the number of slices to 3.

left.createChildNode(new LinearExtrusion(profile, 2) {{ setCenter(false); setSlices(3); }});

Step 5: Set Ground Plane for Reference

Enhance the visual representation by adding a ground plane to the left node.

left.createChildNode(new Box(0.01, 3, 3));

Step 6: Linear Extrusion with Center Property (Right Node)

Perform linear extrusion on the right node, this time centering the extrusion, and again set the number of slices to 3.

right.createChildNode(new LinearExtrusion(profile, 2) {{ setCenter(true); setSlices(3); }});

Step 7: Set Ground Plane for Reference (Right Node)

Similar to the left node, add a ground plane to the right node for reference.

right.createChildNode(new Box(0.01, 3, 3));

Step 8: Save the 3D Scene

Save your 3D scene in Wavefront OBJ format.

scene.save(MyDir + "CenterInLinearExtrusion.obj", FileFormat.WAVEFRONTOBJ);

Conclusion

Controlling the center in linear extrusion with Aspose.3D for Java opens up exciting possibilities in 3D graphics development. By following this step-by-step guide, you’ve learned how to manipulate the center property, allowing you to achieve the desired visual effects in your Java projects.
