A TriRefiner encapsulates a Triangulation object and provides tools for mesh refinement and interpolation.
Derived classes must implement:
refine_triangulation(return_tri_index=False, **kwargs)
, where the optional keyword arguments kwargs are defined in each TriRefiner concrete implementation, and which returns:
a refined triangulation,
optionally (depending on return_tri_index), for each point of the refined triangulation: the index of the initial triangulation triangle to which it belongs.
refine_field(z, triinterpolator=None, **kwargs)
, where:
z array of field values (to refine) defined at the base triangulation nodes,
triinterpolator is an optional TriInterpolator
,
the other optional keyword arguments kwargs are defined in each TriRefiner concrete implementation;
and which returns (as a tuple) a refined triangular mesh and the interpolated values of the field at the refined triangulation nodes.
Abstract base class for classes implementing mesh refinement.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
