Abstract
Un método de codificación de datos tridimensionales codifica una pluralidad de puntos tridimensionales, e incluye: la selección de un modo de predicción entre dos o más modos de predicción para calcular el valor pronosticado de un elemento de información de atributo de un primer punto tridimensional, de acuerdo con los elementos de información de atributo de uno o más segundos puntos tridimensionales en las proximidades del primer punto tridimensional (S3591); el cálculo del valor pronosticado por el modo de predicción seleccionado (S3592); calculando, como predicción residual, una diferencia entre un valor del elemento de información de atributo del primer punto tridimensional y el valor pronosticado calculado (S3593); y generando un primer flujo de bits que incluye el modo de predicción seleccionado, la predicción residual y varios de los dos o más modos de predicción (S3594).
