A system for reconstructing and visualising three-dimensional objects

摘要: Abstract This paper presents a software program for three-dimensional separation, geometrical reconstruction and visualisation of subsurface objects. It uses as input file containing 3-D co-ordinates object points respective attributes converted into grey scale level. The consists two main components: recognition software; software. Based on the file, first component generates set planes, two-dimensional sections. If information needed (i.e. number points) is insufficient, an approximation or interpolation method applied to build smooth 2-D section borders. divides all sections subsets similar second one each subset geometrically different An experiment performed validate capabilities. Data obtained by prospective drills from Aljustrel mine located in South Portugal used generation file. surfaces three ore bodes are reconstructed visualised viewpoints. differences between presented some packages modelling discussed.
