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 `~matplotlib.tri.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. cB[R"[US9 Xlg)N) triangulation)rcheck_isinstancer_triangulation)selfr s K/var/www/html/env/lib/python3.13/site-packages/matplotlib/tri/_trirefine.py__init__TriRefiner.__init__*s m=I+)r N)__name__ __module__ __qualname____firstlineno____doc__r__static_attributes__rr rr s :,rrcT^\rSrSrSrU4SjrSSjrS Sjr\S Sj5r Sr U=r $) UniformTriRefiner/z Uniform mesh refinement by recursive subdivisions.

This function refines the encapsulated triangulation by splitting each father triangle into 4 child sub-triangles built on the edges midside nodes, recursing *subdiv* times. In the end, each triangle is hence divided into ``4**subdiv`` child triangles. Parameters ---------- return_tri_index : bool, default: False Whether an index table indicating the father triangle index of each point is returned. subdiv : int, default: 3 Recursion level for the subdivision. Each triangle is divided into ``4**subdiv`` child triangles; hence, the default results in 64 refined subtriangles for each triangle of the initial triangulation. Returns ------- refi_triangulation : `~matplotlib.tri.Triangulation` The refined triangulation. found_index : int array Index of the initial triangulation containing triangle, for each point of *refi_triangulation*. Returned only if *return_tri_index* is set to True. rdtypeN) r trianglesshapenparangeint32range_refine_triangulation_oncexfullmaskrepeatreshape) r return_tri_indexsubdivrefi_triangulationntri ancestors_ refi_nptsrefi_triangles found_indextri_mask ancestor_masks r refine_triangulation&UniformTriRefiner.refine_triangulation@sp<"00!++11!4IId"((3 vA,0,K,K"-/ )  '((..q1 +55 '')Rrxx@K**//H.0ii 89/;;B72q>+&2 2!) 3 " )*B*+!--4WR^=!+;<!# )N*C*+!--4WR^M>1+<=&2 2% %rc6Uc+[RRURU5nO/[R "[RR US9 UnURUSS9upVURURURUS9SnXW4$)a% Refine a field defined on the encapsulated triangulation.
