阅读 3D 文档

3D 支持的格式列表 (导入)

Aspose.3D for Java API 支持阅读各种类型的 3D 文档。Scene 类的可用构造函数有助于这样做，它们接受有效的文件路径字符串。支持的可读文件格式如下:

1. FBX 7.5 (ASCII，二进制)
2. FBX 7.4 (ASCII，二进制)
3. FBX 7.3 (ASCII，二进制)
4. FBX 7.2 (ASCII，二进制)
5. STL (ASCII，二进制)
6. WavefrontOBJ
7. Discreet3DS
8. Universal3D
9. Collada
10. glTF
11. DXF
12. PLY (ASCII，二进制)
13. X (ASCII，二进制)
14. Draco
15. 3MF
16. RVM (文本，二进制)
17. ASE

Scene类的构造函数在内部检测 3D 文档格式。

导入 3D 文档

Aspose.3D for Java API 支持导入各种类型的 3D 文档，用于修改、添加和处理。

读取 3D 场景: 编程示例

// the path to the documents directory.
String MyDir = RunExamples.getDataDir();
// Initialize a Scene class object
Scene scene = new Scene();
// Load an existing 3D document
scene.open(MyDir + "document.fbx");

使用 3D 属性

Aspose.3D API 允许您使用场景的子节点读取 3D 场景属性。下面的代码示例演示了此功能的用法。

// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
String dataDir = RunExamples.getDataDir();
Scene scene = new Scene(dataDir+ "EmbeddedTexture.fbx");
Material material = scene.getRootNode().getChildNodes().get(0).getMaterial();
PropertyCollection props = material.getProperties();
//List all properties using for loop
for (Property prop:props)
{
    System.out.println("Name" + prop.getName() + " Value = " + prop.getValue());
}
//or using ordinal for loop
for (int i = 0; i < props.size(); i++)
{
    Property prop = props.get(i);
    System.out.println("Name" + prop.getName() + " Value = " + prop.getValue());
}
//Get property value by name
Object diffuse = (Vector3)props.get("Diffuse");
System.out.println(diffuse);
//modify property value by name
props.set("Diffuse", new Vector3(1, 0, 1));
//Get property instance by name
Property pdiffuse = props.findProperty("Diffuse");
System.out.println(pdiffuse);
//Since Property is also inherited from A3DObject
//It's possible to get the property of the property
System.out.println("Property flags = " + pdiffuse.getProperty("flags"));
//and some properties that only defined in FBX file:
System.out.println("Label = " + pdiffuse.getProperty("label"));
System.out.println("Type Name = " + pdiffuse.getProperty("typeName"));
//so traversal on property's property is possible
for (Property pp: pdiffuse.getProperties())
{
	System.out.println("Diffuse. " + pp.getName() + " = " + pp.getValue());
}
