Working with Cylinder

Customize Offset Top

Aspose.3D for 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:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// Create a scene
Scene scene = new Scene();
// Initialize cylinder
Cylinder cylinder1 = new Cylinder(2, 2, 10, 20, 1, false);
// Set OffsetTop
cylinder1.setOffsetTop(new Vector3(5, 3, 0));
// Create ChildNode
scene.getRootNode().createChildNode(cylinder1).getTransform().setTranslation(10, 0, 0);
// Initialize second cylinder without customized OffsetTop
Cylinder cylinder2 = new Cylinder(2, 2, 10, 20, 1, false);
// Create ChildNode
scene.getRootNode().createChildNode(cylinder2);
// Save
scene.save(RunExamples.getDataDir()+ "CustomizedOffsetTopCylinder.obj", FileFormat.WAVEFRONTOBJ);

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 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:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// Create a scene
Scene scene = new Scene();
// Create cylinder 1
Cylinder cylinder1 = new Cylinder(2, 2, 10, 20, 1, false);
// Customized shear bottom for cylinder 1
cylinder1.setShearBottom(new Vector2(0, 0.83));// shear 47.5deg in xy plane(z-axis)
// Add cylinder 1 to the scene
scene.getRootNode().createChildNode(cylinder1).getTransform().setTranslation(10, 0, 0);
// Create cylinder 2
Cylinder cylinder2 = new Cylinder(2, 2, 10, 20, 1, false);
// Add cylinder to without a ShearBottom to the scene
scene.getRootNode().createChildNode(cylinder2);
// Save scene
scene.save(RunExamples.getDataDir()+ "CustomizedShearBottomCylinder.obj", FileFormat.WAVEFRONTOBJ);

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

Create Fan-Cylinder

Aspose.3D for 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:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Jav
// Create a Scene
Scene scene = new Scene();
// Create a cylinder
Cylinder fan = new Cylinder(2, 2, 10, 20, 1, false);
// Set GenerateGanCylinder to true
fan.setGenerateFanCylinder(true);
// Set ThetaLength
fan.setThetaLength(MathUtils.toRadian(270.0));
// Create ChildNode
scene.getRootNode().createChildNode(fan).getTransform().setTranslation(10, 0, 0);
// Create a cylinder without a fan
Cylinder nonfan = new Cylinder(2, 2, 10, 20, 1, false);
// Create ChildNode
scene.getRootNode().createChildNode(nonfan);
// Save scene
scene.save(RunExamples.getDataDir()+ "CreateFanCylinder.obj", FileFormat.WAVEFRONTOBJ);

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