Entity
Example
Example Entity klasa jest abstrakcyjną klasą bazową dla obiektów, które mogą być dołączone do Node w Aspose.3D grafie sceny. Konkretne podklasy obejmują Mesh, Camera, Light, i Geometry. Entity zapewnia dostęp do hierarchii węzłów nadrzędnych i udostępnia getExcluded() metodę kontroli widoczności.
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
Podklasy: Geometry -> Mesh, Camera, Light, i inne.
Example
Entity jest abstrakcyjną klasą bazową i nie jest tworzona bezpośrednio. Użyj konkretnej podklasy, takiej jak 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. |
