Travailler avec l'extrusion linéaire

Exécution de l’extrusion linéaire

Aspose.3D for Java offre LinearExtrusion classe, qui prend une forme 2D en entrée et étend la forme dans la 3ème dimension. L’extrait de code suivant montre comment effectuer une extrusion linéaire:

// 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);

// 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);

Si la méthode setCenter() est définie sur true, la plage d’extrusion est de-Height/2 à Height/2, sinon, l’extrusion est de 0 à Height. L’extrait de code suivant montre comment utiliser la méthode setCenter() dans l’extrusion linéaire:

// 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 dans l’extrusion linéaire

Aspose.3D for Java offre la méthode setTwist() de la classe LinearExtrusion. La méthode setTwist() gère le degré de rotation lors de l’extrusion de la forme. L’extrait de code suivant montre comment utiliser la méthode setTwist() dans l’extrusion linéaire:

// 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
RectangleShape profile = new RectangleShape();
profile.setRoundingRadius(0.3);
// Create a scene
Scene scene = new Scene();
