Travailler avec l'extrusion linéaire

Exécution de l’extrusion linéaire

Aspose.3D for .NET 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-.NET
// Initialize the base profile to be extruded
var profile = new RectangleShape()
{
    RoundingRadius = 0.3
};
// Perform Linear extrusion by passing a 2D profile as input and extend the shape in the 3rd dimension
var extrusion = new LinearExtrusion(profile, 10) { Slices = 100, Center = true, Twist = 360, TwistOffset = new Vector3(10, 0, 0) };
// Create a scene 
Scene scene = new Scene();
// Create a child node by passing extrusion 
scene.RootNode.CreateChildNode(extrusion);
// Save 3D scene
scene.Save("LinearExtrusion.obj");

var right = scene.RootNode.CreateChildNode();
left.Transform.Translation = new Vector3(15, 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) { Slices = 2 });
// Perform linear extrusion on right node using slices property
right.CreateChildNode(new LinearExtrusion(profile, 2) { Slices = 10 });

// Save 3D scene
scene.Save("SlicesInLinearExtrusion.obj");

‘Center’ dans l’extrusion linéaire

Aspose.3D for .NET offre Center propriété de LinearExtrusion classe. Si la propriété Center est définie sur true, la plage d’extrusion est comprise entre-Height/2 et Height/2, sinon, l’extrusion est comprise entre 0 et Height. L’extrait de code suivant montre comment utiliser la propriété Center dans l’extrusion linéaire:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize the base profile to be extruded
var profile = new RectangleShape()
{
    RoundingRadius = 0.3
};
// Create a scene 
Scene scene = new Scene();
// Create left node
var left = scene.RootNode.CreateChildNode();
// Create right node
var right = scene.RootNode.CreateChildNode();
left.Transform.Translation = new Vector3(15, 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) { Slices = 2 });
// Perform linear extrusion on right node using slices property
right.CreateChildNode(new LinearExtrusion(profile, 2) { Slices = 10 });

// Save 3D scene
scene.Save("SlicesInLinearExtrusion.obj");

‘Twist’ dans l’extrusion linéaire

Aspose.3D for .NET offre Twist propriété de LinearExtrusion classe. La propriété Twist gère le degré de rotation lors de l’extrusion de la forme. L’extrait de code suivant montre comment utiliser la propriété Twist dans l’extrusion linéaire:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize the base profile to be extruded
var profile = new RectangleShape()
{
    RoundingRadius = 0.3
};
// Create a scene 
Scene scene = new Scene();
// Create left node
var left = scene.RootNode.CreateChildNode();
// Create rifht node
var right = scene.RootNode.CreateChildNode();
left.Transform.Translation = new Vector3(15, 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) { Twist = 0, Slices = 100 });
// Perform linear extrusion on right node using twist and slices property
right.CreateChildNode(new LinearExtrusion(profile, 10) { Twist = 90, Slices = 100 });

// Save 3D scene
scene.Save("TwistInLinearExtrusion.obj");

‘‘TwistOffset’’ dans l’extrusion linéaire

Aspose.3D for .NET offre TwistOffset propriété de LinearExtrusion classe. La propriété Twist Offset traduit le décalage lors de la rotation de l’extrusion. L’extrait de code suivant montre comment utiliser la propriété TwistOffset dans l’extrusion linéaire:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize the base profile to be extruded
var profile = new RectangleShape()
{
    RoundingRadius = 0.3
};
// Create a scene 
Scene scene = new Scene();
// Create left node
var left = scene.RootNode.CreateChildNode();
// Create right node
var right = scene.RootNode.CreateChildNode();
left.Transform.Translation = new Vector3(18, 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) { Twist = 360, Slices = 100 });
// Perform linear extrusion on right node using twist, twist offset and slices property
right.CreateChildNode(new LinearExtrusion(profile, 10) { Twist = 360, Slices = 100, TwistOffset = new Vector3(3, 0, 0) });

// Save 3D scene
scene.Save(RunExamples.GetOutputFilePath("TwistOffsetInLinearExtrusion.obj"), FileFormat.WavefrontOBJ);

‘Direction’ dans l’extrusion linéaire

Aspose.3D for .NET offre Direction propriété de LinearExtrusion classe. La propriété Direction définit la direction de l’extrusion. L’extrait de code suivant montre comment utiliser la propriété Direction dans une extrusion linéaire:

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-.NET
// Initialize the base profile to be extruded
var profile = new RectangleShape()
{
    RoundingRadius = 0.3
};
// Create a scene 
Scene scene = new Scene();
// Create left node
var left = scene.RootNode.CreateChildNode();
// Create right node
var right = scene.RootNode.CreateChildNode();
left.Transform.Translation = new Vector3(8, 0, 0);

// 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) { Twist = 360, Slices = 100 });
// Perform linear extrusion on right node using twist, slices, and direction property
right.CreateChildNode(new LinearExtrusion(profile, 10) { Twist = 360, Slices = 100, Direction = new Vector3(0.3, 0.2, 1) });
