Générer des UV
Aspose.3D for Java offre une classe PolygonModifier qui expose la méthode GenerateUV, avec laquelle vous pouvez générer manuellement UV et l’associer au maillage. L’extrait de code suivant montre la fonctionnalité complète pour le générer et l’associer:

| 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); |
