It seems that the Renaissance (1300-1700)‚ methods of presenting the surrounding world in a flat pictorial plane using linear perspective‚ has dictated the way artists have worked for countless centuries. Linear perspective is a technique used by artists that uses line to create the illusion of depth and space within their work. However this approach is only a representation created using a singular eye. This method of working is suggested to have originated from Leon Battista Alberti’s (1404-1472)

Search patterns vary and depend on the type of scene‚ the victims and suspect’s actions as well as the location and size of the area. Having someone in command can eliminate or lessen the chances of evidence or effort being duplicated. While each scene and victim may need a different search pattern‚ each pattern searches the probable points of entry first and any exits possibly used by the criminal. A line/strip search is one that is used by one or two investigators who walk in straight lines
