Title
(PT) árvores de octantes de subvolumes
Abstract
(PT) em um exemplo, um método inclui receber um primeiro modelo de dados de um objeto a ser gerado em fabricação de aditivos, em um processador. usando o processador, um segundo modelo de dados pode ser determinado. determinar o segundo modelo de dados pode incluir gerar, para cada um de uma pluralidade de subvolumes contíguos não se sobrepondo de um volume contendo o objeto, uma árvore de octantes (octree) de subvolume tendo como característica o subvolume e tendo um nó raiz. determinar o segundo modelo de dados pode incluir adicionalmente gerar uma árvore de octantes (octree) de volume tendo como característica o volume contendo o objeto, a árvore de octantes (octree) de volume tendo como característica em seus nós mais baixos os nós raízes das árvores de octantes (octrees) de subvolumes.
