mesh_isotropic_remesh — 3D resolution op

• Data kinds: mesh → mesh

• Call: import fullseye as fs; fs.ledger.mesh_isotropic_remesh(V, F, target_edge, iterations=5, project=True, relax=0.5) (implementation को सीधे call करना हो तो import meshres; meshres.mesh_isotropic_remesh(V, F, target_edge, iterations=5, project=True, relax=0.5), registry से लेना हो तो ops3d.get("mesh_isotropic_remesh"))

उपयोग

uniform *target_edge* तक incremental isotropic remeshing (mesh)।

Botsch & Kobbelt, *A Remeshing Approach to Multiresolution Modeling* (SGP 2004): per iteration (1) split edges longer than 4/3·L, (2) collapse edges shorter than 4/5·L into their midpoint when the link condition holds, no incident edge would exceed 4/3·L and no face flips, (3) flip edges that bring the four valences closer to 6, (4) relax each vertex toward its neighbours' centroid in the tangent plane (*relax* ∈ [0,1]),

(5) project the result back onto the input surface (closest point on

the original triangles, *project*=True) so the shape is not smoothed away. Boundary vertices are pinned. The result is a triangle mesh whose edge lengths cluster around L regardless of how the input was sampled — the fix for "coarse and dense regions treated alike". Measured on a pole-clustered UV sphere: edge p95/p5 from 5.6 to < 1.5, area within 2 %, closed manifold preserved (tests/test_meshres.py).
