Geometric Hindrance
Revision as of 14:06, 2 July 2019 by \('"2\)'"7
Overview
Geometric hindrance uses tile geometry to provide additional selection for which tiles may attach beyond glue labels. Tiles or tile assemblies that would overlap in at least some space are not allowed to bind. Models such as the geometric tile assembly model (GTAM) [1] [2] and polygon free-body tile assembly model (pfbTAM) [3] rely on tiles with geometries along each tile face. Other models such as the two-handed assembly model (2HAM) use the shape of the assemblies to select which two assemblies combine into one new assembly. The two-handed geometric tile assembly model (2GAM) combines the GTAM and 2HAM to further restrict which two assemblies can bind into one larger assembly. [1]
An example of tiles with geometric faces. The top two tiles have compatible geometries and can bind, but the bottom two tiles have incompatible geometries that would overlap if they tried to bind.
