产生紫外线

Aspose.3D for Java 提供 PolygonModifier 类，该类公开GenerateUV方法，您可以使用该方法手动生成UV并将其与网格关联。以下代码段显示了生成和关联它的完整功能:

	// For complete examples and data files, please go to https://github.com/aspose-3d/Aspose.3D-for-Java
	// The path to the documents directory.
	String MyDir = RunExamples.getDataDir();
	Scene scene = new Scene();
	//since all primitive entities in Aspose.3D will have builtin UV generation
	//here we manually remove it to assume we have a mesh without UV data
	Mesh mesh = (new Box()).toMesh();
	mesh.getVertexElements().remove(mesh.getElement(VertexElementType.UV));

	//then we can manually generate UV for it
	VertexElement uv = PolygonModifier.generateUV(mesh);
	//generated UV data is not associated with the mesh, we should manually do this
	mesh.addElement(uv);
	//put it to the scene
	Node node = scene.getRootNode().createChildNode(mesh);
	//then save it
	scene.save(MyDir + "test.obj", FileFormat.WAVEFRONTOBJ);
