Abstract
Un ejemplo de método de codificación de una nube de puntos que incluye la determinación de uno o más parámetros de atributos de un atributo de un punto en la nube de puntos de una trama, en donde uno o más parámetros de atributos definen cómo determinar o usar un valor del atributo y son aplicables a una pluralidad de puntos en la nube de puntos; y señalización, en un flujo de bits indicativo de la nube de puntos, el uno o más parámetros de atributo en una estructura de sintaxis que es específica a la trama.
