Methods and apparatus for creating customisable cad image files

摘要: The method of producing an image data file representative a rendered three dimensional includes the steps of: creating master three-dimensional which is with contrasting colours for each different object type in image; plurality fully files realistic surfaces including effects such as shadowing, textures and/or colours; mapping records are used objects types and colour respective type; selecting processing to determine edges using information edge detection process, produce coordinate one or more extracting selected portions correspond surface type, portion boundary being determined by relevant data; combining extracted composite output combination surfaces.
