This video showcases how an initial model of a regular 5-star polygon can be queried and restructured in a series of different arrangements of polylines under similarity transformations. The first two vignettes showcase the search of two arrangements of polylines, a four-line shape and a seven-line shape respectively, that both can interpreted as arrangements of closed polygons, the first as an arrangement of two triangles and the second as a arrangement of three triangles. The final example showcase the successful search of an arbitrary part of the 5-star polygon selected through a lasso operation to demonstrate the ability of the Shape Machine to find all matching copies under similarity transformations, while introducing the idea of a visual query based on fragmentary evidence rather than a constructive specification.
