Lavorare con l'estrusione lineare

Eseguendo l’estrusione lineare

Aspose.3D for Java offre una classe LinearExtrusion, che assume una forma 2D come input ed estende la forma nella terza dimensione. Il seguente frammento di codice mostra come eseguire l’estrusione lineare:

// 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);

Fette in estrusione lineare

Aspose.3D for Java offre il metodo setSlices() della classe LinearExtrusion. SetSlices () metodo definisce il numero di punti intermedi lungo il percorso dell’estrusione. Il seguente frammento di codice mostra come utilizzare il metodo setSlices() nell’estrusione lineare:

// 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);

Centro in estrusione lineare

Aspose.3D for Java offre il metodo setCenter() della classe LinearExtrusion. Se il metodo setCenter() è impostato su true, l’intervallo di estrusione va da-Height/2 a Height/2, altrimenti l’estrusione va da 0 a Height. Il seguente frammento di codice mostra come utilizzare il metodo setCenter() nell’estrusione lineare:

// 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);

Twist in Linear Extrusion

Aspose.3D for Java offre il metodo setTwist() della classe LinearExtrusion. Il metodo setTwist() gestisce il grado di rotazione mentre si estrude la forma. Il seguente frammento di codice mostra come utilizzare il metodo setTwist() nell’estrusione lineare:

// 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 nell’estrusione lineare

Aspose.3D for Java offre il metodo setTwistOffset() della classe LinearExtrusion. Il metodo setTwistOffset() traduce l’offset durante la rotazione dell’estrusione. Il seguente frammento di codice mostra come utilizzare il metodo setTwistOffset() nell’estrusione lineare:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java

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