Performing Linear Extrusion

Aspose.3D for Node.js via Java offers LinearExtrusion class, which takes a 2D shape as an input and extends the shape in the 3rd dimension. Following code snippet shows how to perform linear extrusion:

var aspose = aspose || {};

aspose.threed = require("aspose.threed");

// Initialize the base shape to be extruded
// Initialize the base profile to be extruded
var profile=new aspose.threed.RectangleShape();
profile.setRoundingRadius(0.3);

// Perform Linear extrusion by passing a 2D shape as input and extend the shape in the 3rd dimension
var extrusion =new aspose.threed.LinearExtrusion(profile, 10);
extrusion.setSlices(100);
extrusion.setCenter(true);
extrusion.setTwist(360);
extrusion.setTwistOffset(new aspose.threed.Vector3(10, 0, 0));

// Create a scene
var scene = new aspose.threed.Scene();

// Create a child node by passing extrusion
scene.getRootNode().createChildNode(extrusion);

// Save 3D scene
scene.save("LinearExtrusion.obj");

Slices in Linear Extrusion

Aspose.3D for Node.js via Java offers setSlices() method of LinearExtrusion class. setSlices() method defines the number of intermediate points along the path of the extrusion. Following code snippet shows how to use setSlices() method in linear extrusion:

var aspose = aspose || {};

aspose.threed = require("aspose.threed");

// Initialize the base profile to be extruded
var profile=new aspose.threed.RectangleShape();
profile.setRoundingRadius(0.3);

// Create a scene
var scene = new aspose.threed.Scene();

// Create left node
var left=scene.getRootNode().createChildNode();
// Create right node
var right=scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new aspose.threed.Vector3(5, 0, 0));

// Slices parameter defines the number of intermediate points along the path of the extrusion
// Perform linear extrusion on left node using slices property
var extrusion1 =new aspose.threed.LinearExtrusion(profile, 2);
extrusion1.setSlices(2);
left.createChildNode(extrusion1);

// Perform linear extrusion on right node using slices property
var extrusion2 =new aspose.threed.LinearExtrusion(profile, 2);
extrusion2.setSlices(10);
right.createChildNode(extrusion2);

// Save 3D scene
scene.save("SlicesInLinearExtrusion.obj");

Center in Linear Extrusion

Aspose.3D for Node.js via Java offers setCenter() method of LinearExtrusion class. If the setCenter() method is set to true, the extrusion range is from -Height/2 to Height/2, otherwise, the extrusion is from 0 to Height. Following code snippet shows how to use setCenter() method in linear extrusion:

var aspose = aspose || {};

aspose.threed = require("aspose.threed");

// Initialize the base profile to be extruded
var profile=new aspose.threed.RectangleShape();
profile.setRoundingRadius(0.3);

// Create a scene
var scene = new aspose.threed.Scene();

// Create left node
var left=scene.getRootNode().createChildNode();
// Create right node
var right=scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new aspose.threed.Vector3(5, 0, 0));

// Set ground plane for reference
var box=new aspose.threed.Box(0.01, 3, 3);

// If Center property is true, the extrusion range is from -Height/2 to Height/2, otherwise the extrusion is from 0 to Height
// Perform linear extrusion on left node using center and slices property
var extrusion1 =new aspose.threed.LinearExtrusion(profile, 2);
extrusion1.setSlices(3);
extrusion1.setCenter(false);
left.createChildNode(extrusion1);
left.createChildNode(box);

// Perform linear extrusion on right node using center and slices property
var extrusion2 =new aspose.threed.LinearExtrusion(profile, 2);
extrusion2.setSlices(3);
extrusion2.setCenter(true);
right.createChildNode(extrusion2);
right.createChildNode(box);

// Save 3D scene
scene.save("CenterInLinearExtrusion.obj");

Twist in Linear Extrusion

Aspose.3D for Node.js via Java offers setTwist() method of LinearExtrusion class. The setTwist() method handles the degree of the rotation while extruding the shape. Following code snippet shows how to use setTwist() method in linear extrusion:

var aspose = aspose || {};

aspose.threed = require("aspose.threed");

// Initialize the base profile to be extruded
var profile=new aspose.threed.RectangleShape();
profile.setRoundingRadius(0.3);

// Create a scene
var scene = new aspose.threed.Scene();

// Create left node
var left=scene.getRootNode().createChildNode();
// Create right node
var right=scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new aspose.threed.Vector3(5, 0, 0));

// Twist property defines the degree of the rotation while extruding the profile
// Perform linear extrusion on left node using twist and slices property
var extrusion1 =new aspose.threed.LinearExtrusion(profile, 10);
extrusion1.setSlices(100);
extrusion1.setTwist(0);
left.createChildNode(extrusion1);

// Perform linear extrusion on right node using twist and slices property
var extrusion2 =new aspose.threed.LinearExtrusion(profile, 10);
extrusion2.setSlices(100);
extrusion2.setTwist(90);
right.createChildNode(extrusion2);

// Save 3D scene
scene.save("TwistInLinearExtrusion.obj");

TwistOffset in Linear Extrusion

Aspose.3D for Node.js via Java offers setTwistOffset() method of LinearExtrusion class. The setTwistOffset() method translates offset while rotating the extrusion. Following code snippet shows how to use setTwistOffset() method in linear extrusion:

var aspose = aspose || {};

aspose.threed = require("aspose.threed");

// Initialize the base profile to be extruded
var profile=new aspose.threed.RectangleShape();
profile.setRoundingRadius(0.3);

// Create a scene
var scene = new aspose.threed.Scene();

// Create left node
var left=scene.getRootNode().createChildNode();
// Create right node
var right=scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new aspose.threed.Vector3(5, 0, 0));

// TwistOffset property is the translate offset while rotating the extrusion.
// Perform linear extrusion on left node using twist and slices property
var extrusion1 =new aspose.threed.LinearExtrusion(profile, 10);
extrusion1.setSlices(100);
extrusion1.setTwist(360);
left.createChildNode(extrusion1);

// Perform linear extrusion on right node using twist, twist offset and slices property
var extrusion2 =new aspose.threed.LinearExtrusion(profile, 10);
extrusion2.setSlices(100);
extrusion2.setTwist(360);
extrusion2.setTwistOffset(new aspose.threed.Vector3(3, 0, 0));
right.createChildNode(extrusion2);

// Save 3D scene
scene.save("TwistOffsetInLinearExtrusion.obj");

Direction in Linear Extrusion

Aspose.3D for Node.js via Java offers setDirection() method of LinearExtrusion class. The setDirection() method defines the direction of the extrusion. Following code snippet shows how to use setDirection() method in linear extrusion:

var aspose = aspose || {};

aspose.threed = require("aspose.threed");

// Initialize the base profile to be extruded
var profile=new aspose.threed.RectangleShape();
profile.setRoundingRadius(0.3);

// Create a scene
var scene = new aspose.threed.Scene();

// Create left node
var left=scene.getRootNode().createChildNode();
// Create right node
var right=scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new aspose.threed.Vector3(5, 0, 0));

// Direction property defines the direction of the extrusion.
// Perform linear extrusion on left node using twist and slices property
var extrusion1 =new aspose.threed.LinearExtrusion(profile, 10);
extrusion1.setSlices(100);
extrusion1.setTwist(360);
left.createChildNode(extrusion1);

// Perform linear extrusion on right node using twist, slices, and direction property
var extrusion2 =new aspose.threed.LinearExtrusion(profile, 10);
extrusion2.setSlices(100);
extrusion2.setTwist(360);
extrusion2.setDirection(new aspose.threed.Vector3(0.3, 0.2, 1));
right.createChildNode(extrusion2);
