Abstract
SISTEMA DE VISUALIZACION GRAFICA VECTORIAL CONTROLADO POR COMPUTADOR. EN UN SISTEMA, DONDE LOS VECTORES ESTAN DEFINIDOS POR LAS COORDENADAS DE SUS PUNTOS EXTREMOS Y SUS LONGITUDES SON CALCULADAS A PARTIR DE ESTAS COORDENADAS, SE INCLUYE UN APARATO (1) DE VISUALIZACION, SIENDO ESTE UN TUBO DE ALMACENAMIENTO DE OBSERVACION DIRECTA (DVST), SOBRE EL CUAL PUEDEN OBSERVARSE PRESENTACIONES VISUALES GRAFICAS VECTORIALES. PARA CONTROLAR LA POSICION DEL HAZ SOBRE EL DISPOSITIVO (1) DE VISUALIZACION, SE DESARROLLAN SEÑALES DE UN CIRCUITO (2) DE CONTROL DE DEFLEXION DE LA ABSCISA X Y UN CIRCUITO (3) DE CONTROL DE DEFLEXION DE LA ORDENADA. Y AMBOS CIRCUITOS SON IDENTICOS Y DISPONEN DE UN GENERADOR (9) DE DIFERENCIA ABSOLUTA QUE DETERMINA EN TODO MOMENTO LOS INCREMENTOS HABIDOS EN ABSCISAS Y ORDENADAS.
