Base Classes — Aspose.3D FOSS for Java

Paket: com.aspose.threed (aspose-3d-foss 26.1.0)

Ove tri klase čine osnovu Aspose.3D hijerarhije klasa. Svaki javni objekat u biblioteci nasleđuje od A3DObject, koja pruža ime i dinamičku kolekciju svojstava. SceneObject proširuje A3DObject sa praćenjem članstva u sceni. CustomObject je lagana konkretna podklasa za čuvanje proizvoljnih korisničkih metapodataka.

A3DObject

Osnovna korenska klasa za sve Aspose.3D upravljane objekte. Svaki imenovani objekat u biblioteci – Node, Mesh, AnimationClip, Material, i tako dalje – nasleđuje od A3DObject.

import com.aspose.threed.A3DObject;

Example

ClassDescription
A3DObjectRoot base class for all Aspose.3D managed objects. Provides a name property and a Properties collection for user-defined metadata.
SceneObjectBase class shared by Node and Entity . Provides the property collection interface used for user-defined metadata.
CustomObjectLightweight A3DObject subclass that carries only a name and an arbitrary PropertyCollection . Used for storing user-defined metadata on scene objects.
EntityBase class for all scene entities ( Mesh , Camera , Light , etc.). Attached to a Node via Node.addEntity() .
DeformerBase class for deformers that modify mesh geometry (e.g., skinning, morph targets).

Example

findProperty(String propertyName)

Pretražite imenovanu osobinu u ovom objektu PropertyCollection i vratite Property instancu, ili null ako nije pronađeno.

Vraća: Property ili null

import com.aspose.threed.Scene;

Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("origin");
Property prop = node.findProperty("name");
if (prop != null) {
    System.out.println(prop.getValue());   // "origin"
}

getProperty(String property)

Vrati trenutnu vrednost imenovane osobine, ili null ako osobina ne postoji.

Vraća: Object

Object val = node.getProperty("name");
System.out.println(val);   // "origin"

setProperty(String property, Object value)

Postavlja vrednost imenovane osobine. Kreira osobinu ako već ne postoji.

Vraća: void

node.setProperty("layer", 3);
System.out.println(node.getProperty("layer"));   // 3

removeProperty(String property)

Uklonite imenovanu osobinu iz kolekcije.

Vraća: boolean – true ako je svojstvo pronađeno i uklonjeno.

Example 

import com.aspose.threed.Scene;
import com.aspose.threed.Node;
import com.aspose.threed.Property;

Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("my_node");

// Set and retrieve a custom property
node.setProperty("export_lod", 2);
System.out.println(node.getProperty("export_lod"));   // 2

// Enumerate all properties
for (Property prop : node.getProperties()) {
    System.out.println("  " + prop.getName() + " = " + prop.getValue());
}

// Find and inspect a specific property
Property p = node.findProperty("name");
if (p != null) {
    System.out.println(p.getValueType());   // java.lang.String
}

SceneObject

Example A3DObject sa referencom na vlasnika Scene. Node, Entity, i povezane klase nasleđuju od SceneObject.

import com.aspose.threed.SceneObject;

Example

A3DObject -> SceneObject

Dodatno svojstvo 

import com.aspose.threed.Scene;

Scene scene = new Scene();
Node node = scene.getRootNode().createChildNode("child");
System.out.println(node.getScene() == scene);   // true

CustomObject

Lagana konkretna podklasa od A3DObject koji nosi samo ime i proizvoljan PropertyCollection. Koristite ga da prikačite slobodno‑formirane metapodatke na scenu bez podklasiranja bilo kog tipa entiteta.

import com.aspose.threed.CustomObject;

Example

A3DObject -> CustomObject

Example 

CustomObject()
CustomObject(String name)

Example 

import com.aspose.threed.CustomObject;
import com.aspose.threed.Scene;

// Attach pipeline metadata to a scene as a custom object
CustomObject meta = new CustomObject("render_settings");
meta.setProperty("max_bounces", 8);
meta.setProperty("use_denoiser", true);

Scene scene = new Scene();
scene.getRootNode().setProperty("render_meta", meta.getName());
System.out.println(meta.getProperty("max_bounces"));   // 8
