Entity

Example

Example Entity klass är den abstrakta basklassen för objekt som kan fästas på en Node i Aspose.3D-scengrafen. Konkret underklasser inkluderar Mesh, Camera, Light, och Geometry. Entity ger åtkomst till föräldranodens hierarki och exponerar den getExcluded() metod för synlighetskontroll.

import com.aspose.threed.Scene;
import com.aspose.threed.*;

Scene scene = Scene.fromFile("model.obj");

for (Node node : scene.getRootNode().getChildNodes()) {
    Entity entity = node.getEntity();
    if (entity != null) {
        if (!entity.getExcluded()) {
            Node parent = entity.getParentNode();
            System.out.println("Active entity '" + entity.getName()
                + "', parent: " + (parent != null ? parent.getName() : "None"));
        }
    }
}

Example

A3DObject -> SceneObject -> Entity

Underklasser: Geometry -> Mesh, Camera, Light, och andra.

Example

Entity är en abstrakt basklass och instansieras inte direkt. Använd en konkret underklass såsom Mesh.

Example

Name	Type	Access	Description
`parentNode`	`Node`	Read	Gets the parent node.
`parentNodes`	`ArrayList<Node>`	Read	Gets the parent nodes.
`excluded`	`boolean`	Read	Gets the excluded.
`boundingBox`	`BoundingBox`	Read	Gets the bounding box.
`scene`	`Scene`	Read	Gets the scene.
`name`	`String`	Read	Gets the name.
`properties`	`PropertyCollection`	Read	Gets the properties.

Example

Signature	Description
`Entity()`	NURBS curve is a curve represented by NURBS(Non-uniform rational basis spline), A NURBS curve is defined by its getOrder(), a set of weighted Geometry.getControlPoints() and a getKnotVectors() The w component in control point is used as control point’s weight, whatever it is a CurveDimension.TWO_DIMENSIONAL or CurveDimension.THREE_DIMENSIONAL
`Entity(name: String)`	Creates a new Entity with the given name
`getParentNode()` → `Node`	Constructor of instance.
`setParentNode(value: Node)`	The Boolean operator used in the operation to create the result mesh.
`getParentNodes()` → `ArrayList<Node>`	Protected constructor to allow derived classes to set name.
`getExcluded()` → `boolean`	The Boolean operator used in the operation to create the result mesh.
`setExcluded(value: boolean)`	Sets the excluded value.
`getBoundingBox()` → `BoundingBox`	The first operand of the Boolean operator.
`SceneObject()`	Boolean operator allows you to apply Boolean operation on two IMeshConvertible instances.
`getScene()` → `Scene`	Constructor of BooleanOperator.
`A3DObject()`	Parameterized Cylinder. It can also be used to represent a cone when one of radiusTop/radiusBottom is zero.
`getName()` → `String`	The segments of the curve.
`setName(name: String)`	Constructs a CircleShape profile with specified radius.
`getProperties()` → `PropertyCollection`	Initializes a new instance of Cylinder class.
`findProperty(name: String)` → `Property`	Initializes a new instance of the Bone class.
`getProperty(name: String)` → `Object`	Gets the transform matrix of the node in current pose.
`setProperty(name: String, value: Object)`	Gets the width segments.
`removeProperty(name: String)` → `boolean`	Gets flip coordinate system of control points/normal during importing/exporting.

Example

Inspektera enhetens tillstånd efter att en scen har laddats:

import com.aspose.threed.Scene;
import com.aspose.threed.Node;
import com.aspose.threed.Entity;
import com.aspose.threed.*;

Scene scene = Scene.fromFile("model.stl");

for (Node node : scene.getRootNode().getChildNodes()) {
    Entity entity = node.getEntity();
    if (entity == null) continue;

    System.out.println("Entity: " + (entity.getName().isEmpty() ? "(unnamed)" : entity.getName()));
    System.out.println("  Type: " + entity.getClass().getSimpleName());
    System.out.println("  Excluded: " + entity.getExcluded());
    System.out.println("  Parent node: "
        + (entity.getParentNode() != null ? entity.getParentNode().getName() : "None"));

    if (entity instanceof Mesh) {
        Mesh mesh = (Mesh) entity;
        System.out.println("  Vertices: " + mesh.getControlPoints().size());
        System.out.println("  Polygons: " + mesh.getPolygonCount());
    }
}
