ADDON. Version 3.0. Released on 2020-01-09. Provides 122 components. Created by Ortler Mark. Features 0 video tutorials.
A QuadEdgeDataStructure is used to represent a n-gonal Mesh without making any difference between primal and dual elements. The (relativ) dual-graph is holded in a valid state during any topological operation. The implementation used in Grasshopper is embedded into the euclidean space. The solvers for the graph-analytic-tools are working with ‚GH_Variant‚ values, which are provided by evaluating a string-expression against the QuadElement of investigation. The components use a special zoom-interface. While UI-Elements are practicable to clarify an option, they are not if the value for the option should be set from the computation-tree. Therefor almost any UI-Element can be converted to a parameter.
