Class EdgeLoopRemesher

This is a custom Remesher that only affects the edges along an EdgeLoop. The edges are only split and collapsed, flipping is not permitted. The loop vertices are smoothed along the loop, ie using curve laplacian rather than one-ring laplacian.

[TODO] avoid rebuild_edge_list(). requires handling various cases below... [TODO] Precompute() seems overly expensive...? [TODO] local-smoothing impl is not very efficient. Should not be necessary to rebuild nbrhood each time if we are not changing it.

Constructors

EdgeLoopRemesher(DMesh3, EdgeLoop)

Declaration
public EdgeLoopRemesher(DMesh3 m, EdgeLoop loop)
Parameters
Type Name Description
DMesh3 m
EdgeLoop loop

Fields

InputLoop

Declaration

public int LocalSmoothingRings
Field Value
Type Description
Int32

OutputLoop

Declaration
public EdgeLoop OutputLoop
Field Value
Type Description
EdgeLoop
