Title (EN) THREE-DIMENSIONAL PRESENTATION OF STRUCTURE
(FR) REPRESENTATION TRIDIMENSIONNELLE DE STRUCTURES
Abstract:
(EN) In a three-dimensional presentation method of a structure, a rectangular parallelepiped (RP) having the sides (LX, LY, LZ) equal to the respective distances between the nearest and farthest positions of a structure (SML) along the three axes from the origin is constituted of a number of identical cubes (UC), and the structure is expressed by the data that indicate whether the unit cubes constitute the structure (SML) or not. The individual unit cubes constituting the structure (SML) are successively drawn starting from the ones that are seen from the observer. The planes of unit cubes overlapped on the planes of the unit cubes that are drawn already are not drawn, and only those planes that are visually located near the observer are drawn to provide a perspective view of a three-dimensional structure (SML).
(FR) Procédé de représentation tridimensionnelle de structures, dans lequel un parallélépipède rectangulaire (RP), possédant des côtés (LX, LY, LZ) égaux aux distances respectives entre les positions les plus proches et les positions les plus éloignées d'une structure (SML) le long des trois axes à partir de l'origine est constitué d'un certain nombre de cubes identiques (UC), et la structure est exprimée par des données qui indiquent si les cubes unitaires constituent ou non la structure (SML). Les cubes unitaires individuels constituant la structure (SML) sont tracés successivement en commençant par ceux qui sont vus par l'observateur. Les plans des cubes unitaires qui se superposent aux plans des cubes unitaires déjà représentés ne sont pas tracés, et uniquement les plans qui sont situés visuellement à proximité de l'observateur sont tracés pour obtenir une représentation en perspective d'une structure tridimensionnelle (SML).
