Abstract

Se proporcionan métodos, aparatos, sistemas, arquitecturas e interfaces para codificar y/o decodificar flujos de bits de nube de puntos que incluyen secuencias de nube de puntos codificadas. Entre tales métodos, aparatos, sistemas, arquitecturas, e interfaces se incluye un aparato que puede incluir un procesador y una memoria. Un método puede incluir cualquiera de: mapear componentes del flujo de bits de nube de puntos en las pistas; generar información que identifica cualquiera de los flujos de geometría o flujos de textura de acuerdo con el mapeo de los componentes; generar información asociada con capas que corresponden a los respectivos flujos de componentes de geometría; y generar información que indica los puntos de operación asociados con el flujo de bits de nube de puntos.
