Methods

can_collapse_constraints(Int32, Int32, Int32, Int32, Int32, Int32, Int32, out Int32)

Declaration

Parameters
Type Name Description
Int32 eid
Int32 a
Int32 b
Int32 c
Int32 d
Int32 tc
Int32 td
Int32 collapse_to
Returns
Type Description
Boolean

can_collapse_vtx(Int32, Int32, Int32, out Int32)

Declaration
protected bool can_collapse_vtx(int eid, int a, int b, out int collapse_to)
Parameters
Type Name Description
Int32 eid

Cancelled()

if this returns true, abort computation.

Declaration
protected virtual bool Cancelled()
Returns
Type Description
Boolean

collapse_creates_flip_or_invalid(Int32, Int32, ref Vector3d, Int32, Int32)

check if edge collapse will create a face-normal flip. Also checks if collapse would violate link condition, since we are iterating over one-ring anyway.

This only checks one-ring of vid, so you have to call it twice, with vid and vother reversed, to check both one-rings

Declaration
protected bool collapse_creates_flip_or_invalid(int vid, int vother, ref Vector3d newv, int tc, int td)
Parameters
Type Name Description
Int32 vid
Int32 vother
Vector3d newv
Int32 tc
Int32 td
Returns
Type Description
Boolean

edge_flip_metric(ref Vector3d, ref Vector3d)

Declaration
protected double edge_flip_metric(ref Vector3d n0, ref Vector3d n1)
Parameters
Type Name Description
Vector3d n0
Vector3d n1
Returns
Type Description
Double

flip_inverts_normals(Int32, Int32, Int32, Int32, Int32)

Check if edge flip might reverse normal direction.

Not entirely clear on how to implement this test. Currently checking if any normal-pairs are reversed.

Declaration
protected bool flip_inverts_normals(int a, int b, int c, int d, int t0)
Parameters
Type Name Description
Int32 a
Int32 b
Int32 c
Int32 d
Int32 t0
Returns
