Working with Cylinder

Customize Offset Top

Aspose.3D for Node.js via Java allows customizing Offset Top of a cylinder. In order to use this functionality, you can use setOffsetTop() method of Cylinder class. The following code snippet shows how to customize Offset Top:

var aspose = aspose || {};

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

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

// Initialize cylinder
var cylinder1 =new aspose.threed.Cylinder(2, 2, 10, 20, 1, false);

// Set OffsetTop
cylinder1.setOffsetTop(new aspose.threed.Vector3(5, 3, 0));

// Create ChildNode
var node1=scene.getRootNode().createChildNode(cylinder1);
node1.getTransform().setTranslation(new aspose.threed.Vector3(10, 0, 0));

// Initialize second cylinder without customized OffsetTop
var cylinder2 =new aspose.threed.Cylinder(2, 2, 10, 20, 1, false);

// Create ChildNode
scene.getRootNode().createChildNode(cylinder2);

// Save
scene.save("CustomizedOffsetTopCylinder.obj");

The left one has OffsetTop set to (5, 3, 0), it’s easy to see the top cap has moved and the whole torso also gets affected.

Customize ShearBottom

Aspose.3D for Node.js via Java allows customizing shear bottom of a cylinder. In order to use this functionality, you can use setShearBottom() property of Cylinder class. The following code snippet shows how to customize Shear Bottom:

var aspose = aspose || {};

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

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

// Create cylinder 1
var cylinder1 =new aspose.threed.Cylinder(2, 2, 10, 20, 1, false);

// Customized shear bottom for cylinder 1
cylinder1.setShearBottom(new aspose.threed.Vector2(0, 0.83));

// Add cylinder 1 to the scene
var node1=scene.getRootNode().createChildNode(cylinder1);
node1.getTransform().setTranslation(new aspose.threed.Vector3(10, 0, 0));

// Create cylinder 2
var cylinder2 =new aspose.threed.Cylinder(2, 2, 10, 20, 1, false);

// Add cylinder to without a ShearBottom to the scene
scene.getRootNode().createChildNode(cylinder2);

// Save scene
scene.save("CustomizedShearBottomCylinder.obj");

The left cylinder has ShearBottom to (0, 0.83) while the right one is an ordinal cylinder.

Create Fan-Cylinder

Aspose.3D for Node.js via Java allows creating a fan cylinder. In order to use this functionality, you can setGenerateFanCylinder() property of Cylinder class to true. The following code snippet shows how to use this functionality:

var aspose = aspose || {};

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

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

// Create a cylinder
var fan  =new aspose.threed.Cylinder(2, 2, 10, 20, 1, false);

// Set GenerateGanCylinder to true
fan.setGenerateFanCylinder(true);

// Set ThetaLength
fan.setThetaLength(aspose.threed.MathUtils.toRadian(270.0));

// Create ChildNode
var node1=scene.getRootNode().createChildNode(fan);
node1.getTransform().setTranslation(new aspose.threed.Vector3(10, 0, 0));

// Create a cylinder without a fan
var nonfan  =new aspose.threed.Cylinder(2, 2, 10, 20, 1, false);

// Create ChildNode
scene.getRootNode().createChildNode(nonfan);

// Save scene
scene.save("CreateFanCylinder.obj");

The left cylinder has GenerateFanCylinder = false and the right one has GenerateFanCylinder = true.
