Editing Scale model (section)

===Television and film production===
{{Main|Miniature effect}}
Before the advent of [[computer-generated imagery]] (CGI), visual effects of vehicles such as marine ships and spaceships were created by filming "miniature" models. These were considerably larger scale than hobby versions to allow inclusion of a high degree of surface detail, and electrical features such as interior lighting and animation. For ''[[Star Trek: The Original Series]]'', a {{convert|33|in|m|adj=on}} pre-production model of the [[Starship Enterprise|Starship ''Enterprise'']] was created in December 1964, mostly of pine, with Plexiglass and brass details, at a cost of $600.<ref name=":16">{{Cite journal|last=McCullars|first=William S.|date=2001|title=Enterprise '64, Part 1|journal=Star Trek Communicator|issue=132|pages=51}}</ref> This was followed by a {{convert|135.5|in|m|adj=on}} production model constructed from plaster, sheet metal, and wood, at ten times the cost of the first.{{sfn|Eaglemoss|2013|p=17}}{{sfn|Weitekamp|2016|p=5}} As the ''Enterprise'' was originally reckoned to be {{convert|947|ft|m}} long, this put the models at 1:344 and 1:83.9 scale respectively. The [[Polar Lights (models)|Polar Lights]] company sells a large plastic ''Enterprise'' model kit essentially the same size as the first TV model, in 1:350 scale (32 inches long). It can be purchased with an optional electronic lighting and animation (rotating engine domes) kit.
