Camera

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

Camera es una Entity que define un punto de vista en una escena 3D. Controla cómo la escena se proyecta en un plano de imagen 2D. Una cámara está vinculada a un Node para posicionarla y orientarla en la escena.

public class Camera extends Entity

A3DObject -> SceneObject -> Entity -> Camera

Notas de implementación

En la edición FOSS de Java, el Camera la clase solo tiene constructores — no se implementan propiedades específicas de la cámara (campo de visión, plano cercano/lejos, modo de proyección).

Limitación de exportación: Las entidades de cámara son no se escriben al exportar escenas. El exportador glTF (GltfExporter) procesa solo Mesh entidades — Los nodos de cámara se omiten silenciosamente. Esto significa que una cámara adjunta a un nodo no aparecerá en ningún archivo exportado. El ejemplo “Read Camera After Import” a continuación muestra cómo leer los nombres de cámara de un archivo importado; sin embargo, escribir cámaras de nuevo a un archivo no es compatible en esta edición.
