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

NameTypeAccessDescription
parentNodeNodeReadGets the parent node.
parentNodesArrayList<Node>ReadGets the parent nodes.
excludedbooleanReadGets the excluded.
boundingBoxBoundingBoxReadGets the bounding box.
sceneSceneReadGets the scene.
nameStringReadGets the name.
propertiesPropertyCollectionReadGets the properties.

Example

SignatureDescription
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() → NodeConstructor 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() → booleanThe Boolean operator used in the operation to create the result mesh.
setExcluded(value: boolean)Sets the excluded value.
getBoundingBox() → BoundingBoxThe first operand of the Boolean operator.
SceneObject()Boolean operator allows you to apply Boolean operation on two IMeshConvertible instances.
getScene() → SceneConstructor of BooleanOperator.
A3DObject()Parameterized Cylinder. It can also be used to represent a cone when one of radiusTop/radiusBottom is zero.
getName() → StringThe segments of the curve.
setName(name: String)Constructs a CircleShape profile with specified radius.
getProperties() → PropertyCollectionInitializes a new instance of Cylinder class.
findProperty(name: String) → PropertyInitializes a new instance of the Bone class.
getProperty(name: String) → ObjectGets the transform matrix of the node in current pose.
setProperty(name: String, value: Object)Gets the width segments.
removeProperty(name: String) → booleanGets 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());
    }
}
