Abstract

DISPOSITIVO DE PROCESSAMENTO DE IMAGEM, MéTODO DE PROCESSAMENTO DE IMAGEM, E MEIO DE DISTRIBUIçãO DE PROGRAMA E MEIO DE DISTRIBUIçãO DE DADOS, para tornar possível a geração de uma imagem de forma detalhada a partir de formas rudimentares e, para tanto, trata-se da obtenção de um sub-polígono que tem uma forma tridimensional uniforme a partir de um polígono, onde uma curva de Bezier, como a linha interpolada B~ 12~ que interpola entre os vértices P~ 1~ e P~ 2~ do polígono quadrilátero P~ 1~P~ 2~P~ 4~P~ 3~, é determinada utilizando-se os normais vetores n~ 1~ e n~ 2~, e uma linha interpolada B~ 34~ que interpola entre os vértices P~ 3~ e P~ 4~ é determinada utilizando-se os vetores normais n~ 3~ e n~ 4~; então, os pontos interpolados P~ 12~ e P~ 34~ são determinados nas linhas interpoladas B~ 12~ e B~ 34~, sendo que, ainda, analogamente, uma linha interpolada B~ 13~que interpola entre os vértices P~ 1~ e P~ 3~ e uma linha interpolada B~ 24~ que interpolando entre os vértices P~ 2~ e P~ 4~ são determinadas; então, os pontos interpolados P~ 13~ e P~ 24~ são determinados nas linhas interpoladas B~ 13~ e B~ 24~; da mesma maneira, uma linha interpolada B~ 1234~ que interpola entre os pontos interpolados P~ 12~ e P~ 34~ é determinada, e um ponto interpolado P~ 1234~ é determinado na linha interpolada B~ 1234~. Analogamente, o polígono quadrilátero P~ 1~P~ 2~P~ 4~P~ 3~ é dividido em quatro sub-polígonos, os polígonos quadriláteros P~ 1~P~ 12~P~ 1234~P~ 13~, P~ 12~P~ 2~P~ 24~P~ 1234~, P~ 1234~P~ 24~P~ 4~P~ 34~ e P~ 13~P~ 1234~P~ 34~P~ 3~.
