Arbeta med linjär extrusion

Utför linjär extrusion

Aspose. 3D for Java erbjuder LinearExtrusion klass, som tar en 2D-form som ingång och utökar formen i den tredje dimensionen. Följande kod snutt visar hur man utför linjär extrusion:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize the base shape to be extruded
// Initialize the base profile to be extruded
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);
// Perform Linear extrusion by passing a 2D shape as input and extend the shape in the 3rd dimension
LinearExtrusion extrusion = new LinearExtrusion(profile, 10) {{ setSlices(100); setCenter(true); setTwist(360); setTwistOffset(new Vector3(10, 0, 0));}};
extrusion.setSlices(100);
extrusion.setCenter(true);
extrusion.setTwist(360);
extrusion.setTwistOffset(new Vector3(10, 0, 0));
// Create a scene
Scene scene = new Scene();
// Create a child node by passing extrusion
scene.getRootNode().createChildNode(extrusion);
// Save 3D scene
scene.save(MyDir +  "LinearExtrusion.obj", FileFormat.WAVEFRONTOBJ);

Skivor i linjär extrusion

Aspose.3D for Java erbjuder setSlices() metod för LinearExtrusion klass. SetSlices () metoden definierar antalet mellanpunkter längs strängvägen. Följande kodutdrag visar hur man använder setSlices () metoden i linjär extrusion:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize the base profile to be extruded
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);
// Create a scene
Scene scene = new Scene();
// Create left node
Node left = scene.getRootNode().createChildNode();
// Create right node
Node right = scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new 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
left.createChildNode(new LinearExtrusion(profile, 2) {{setSlices(2);}});
// Perform linear extrusion on right node using slices property
right.createChildNode(new LinearExtrusion(profile, 2) {{setSlices(10);}});

// Save 3D scene
scene.save(MyDir + "SlicesInLinearExtrusion.obj", FileFormat.WAVEFRONTOBJ);

Centrum i linjär extrusion

Aspose.3D for Java erbjuder setCenter() metod för LinearExtrusion klass. Om setCenter () metoden är inställd till true är extruderingsområdet från -Höjd/2 till höjd/2, annars. extruderingen är från 0 till höjd. Följande kod snippet visar hur man använder setCenter() metod i linjär extrusion:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize the base profile to be extruded
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);
// Create a scene
Scene scene = new Scene();
// Create left node
Node left = scene.getRootNode().createChildNode();
// Create right node
Node right = scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new Vector3(5, 0, 0));

// 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
left.createChildNode(new LinearExtrusion(profile, 2) {{ setCenter(false); setSlices(3); }});
// Set ground plane for reference
left.createChildNode(new Box(0.01, 3, 3));
// Perform linear extrusion on left node using center and slices property
right.createChildNode(new LinearExtrusion(profile, 2) {{ setCenter(true); setSlices(3); }});
// Set ground plane for reference
right.createChildNode(new Box(0.01, 3, 3));

// Save 3D scene
scene.save(MyDir + "CenterInLinearExtrusion.obj", FileFormat.WAVEFRONTOBJ);

Vridning i linjär utsträckning

Aspose.3D for Java erbjuder setTwist() metod för LinearExtrusion klass. Metoden setTwist () hanterar rotationsgraden samtidigt som den extruderar formen. Följande kod snutt visar hur man använder setTwist () metod i linjär extrusion:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize the base profile to be extruded
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);
// Create a scene
Scene scene = new Scene();
// Create left node
Node left = scene.getRootNode().createChildNode();
// Create right node
Node right = scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new 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
left.createChildNode(new LinearExtrusion(profile, 10) {{ setTwist(0); setSlices(100); }});
// Perform linear extrusion on right node using twist and slices property
right.createChildNode(new LinearExtrusion(profile, 10) {{ setTwist(90); setSlices(100); }});

// Save 3D scene
scene.save(MyDir + "TwistInLinearExtrusion.obj", FileFormat.WAVEFRONTOBJ);

TwistOffset i linjär utsträckning

Aspose.3D for Java erbjuder setTwistOffset() metod för LinearExtrusion klass. Metoden setTwistOffset () översätter offset medan man roterar extruderingen. Följande kod snutt visar hur man använder setTwistOffset() metod i linjär extrusion:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize the base profile to be extruded
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);
        
// Create a scene
Scene scene = new Scene();
// Create left node
Node left = scene.getRootNode().createChildNode();
// Create right node
Node right = scene.getRootNode().createChildNode();
left.getTransform().setTranslation(new 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
left.createChildNode(new LinearExtrusion(profile, 10) {{ setTwist(360); setSlices(100); }});
// Perform linear extrusion on right node using twist, twist offset and slices property
right.createChildNode(new LinearExtrusion(profile, 10)  {{setTwist(360); setSlices(100); setTwistOffset(new Vector3(3, 0, 0));}});

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
// The path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize the base profile to be extruded

profile.setRoundingRadius(0.3);
// Create a scene
Scene scene = new Scene();
// Create left node
Node left = scene.getRootNode().createChildNode();

// Direction property defines the direction of the extrusion.
// Perform linear extrusion on left node using twist and slices property
left.createChildNode(new LinearExtrusion(profile, 10) {{ setTwist(360); setSlices(100); }});
// Perform linear extrusion on right node using twist, slices, and direction property
