Generate UV

Generate UV

Aspose.3D for Java offers PolygonModifier class which exposes GenerateUV method, with which you can manually generate UV and associate it with the mesh. Following code snippet shows complete functionality to generate and associate it:

// 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);
