Abstract
UN APARATO PARA SOMBREAR UNA IMAGEN TRIDIMENSIONAL PARA VISUALIZACION EN UNA PANTALLA FUNCIONA SUMINISTRANDO EN PRIMER LUGAR DATOS QUE DEFINEN UN GRUPO DE SUPERFICIES INFINITAS QUE REPRESENTAN CADA OBJETO EN LA IMAGEN. UN VALOR DE PROFUNDIDAD ES GENERADO POR CADA SUPERFICIE PARA CADA AREA ELEMENTAL DE LA PANTALLA DEPENDIENDO DE LA DISTANCIA DE ESA SUPERFICIE DESDE UN PLANO DE IMAGEN. EL APARATO DETERMINA ENTONCES SI CUALQUIER SUPERFICIE ES VISIBLE O NO EN ESE AREA ELEMENTAL. PUEDEN DESIGNARSE UNO O MAS OBJETOS COMO UN VOLUMEN LUMINOSO. SE DETERMINA UN VALOR DE PROFUNDIDAD PARA CADA SUPERFICIE DEL VOLUMEN LUMINOSO PARA CADA AREA ELEMENTAL DE LA PANTALLA DEPENDIENDO DE LA DISTANCIA DE ESA SUPERFICIE DESDE UN PLANO DE IMAGEN. EL AREA ELEMENTAL DE LA PANTALLA ES ENTONCES SOMBREADA DEPENDIENDO DE LA SUPERFICIE DEL OBJETO VISIBLE EN ESE AREA ELEMENTAL Y SU LOCALIZACION EN RELACION AL VOLUMEN LUMINOSO. PARA FACILITAR UN PROCESAMIENTO MAS FACIL DEL SOMBREADO LA PANTALLA PUEDE SER SUBDIVIDIDA EN UNAPLURALIDAD DE SUB-REGIONES. EL TAMAÑO DE LAS SUB-REGIONES DEPENDE DE LA COMPLEJIDAD DE LA IMAGEN DE CADA AREA EN LA PANTALLA. PREFERIBLEMENTE LA DETERMINACION DE LOS VALORES DE PROFUNDIDAD PARA SUPERFICIES DE GRUPOS DE PIXELS EN UNA SUB-REGION ES INTERCALADA CON LA DETERMINACION DE VALORES DE PROFUNDIDAD PARA SUPERFICIES PARA GRUPOS DE PIXELS EN OTRAS SUB-REGIONES. EL APARATO QUE LLEVA A CABO EL PROCESAMIENTO COMPRENDE UNA PLURALIDAD DE GRUPOS DE ELEMENTOS DE PROCESAMIENTO PARA DETERMINAR VALORES DE PROFUNDIDAD PARA SUPERFICIES EN LA IMAGEN DE CADA AREA ELEMENTAL DE LA PANTALLA. CADA GRUPO DE ELEMENTOS DE PROCESAMIENTO TIENE UNA MEMORIA CACHE ASOCIADA PARA ALMACENAR QUE DEFINE LAS DIFERENTES SUPERFICIES EN LA IMAGEN. LOS GRUPOS DE ELEMENTOS DE PROCESAMIENTO SON ACOPLADOS MEDIANTE UN BUS. LOS DATOS LEIDOS DE LA MEMORIA ASOCIADA DEL PRIMER GRUPO DE ELEMENTOS DE PROCESAMIENTO SON TRANSMITIDOS MEDIANTE EL BUS A OTROS GRUPOS DE ELEMENTOS DE PROCESAMIENTO PARA LA DETERMINACION DE VALORES DE PROFUNDIDAD HASTA QUE TODOS LOS DATOS DEL PRIMER ELEMENTO DE MEMORIA ASOCIADOS HAYAN SIDO LEIDOS. A CONTINUACION TIENE LUGAR LA LECTURA DE LOS DATOS DE LOS ELEMENTOS DE MEMORIA ASOCIADOS DE UN SEGUNDO GRUPO DE ELEMENTOS DE PROCESAMIENTO Y ASI SUCESIVAMENTE.
