Include

#include "Operations/JoinMeshLoops.h"

Syntax

class FJoinMeshLoops

Remarks

FJoinMeshLoops connects two open loops of a mesh with a quad-strip. A 1-1 match between the loop vertices is assumed.

The fill strip currently is configured so that:

  • entire strip is assigned a new face group

  • the entire strip becomes a separate "normal island", ie hard normals at border with existing mesh

  • the strip is unwrapped into a UV rectangle starting at vertex 0 and ending back at 0 again

Variables

Name Description

Public variable

TArray< FIndex2...

 

JoinQuads

Quads along the join strip, in order of loops. Each quad is two triangle indices

Public variable

TArray< int32 >

 

JoinTriangles

Triangles of the quads flattend out (convenient), ie size = 2*NumQuads

Public variable

TArray< int32 >

 

LoopA

First loop

Public variable

TArray< int32 >

 

LoopB

Second loop

Public variable

FDynamicMesh3 &...

 

Mesh

InputsThe mesh that we are modifying

Public variable

TArray< int32 >

 

NewGroups

Groups created by the operation (currently 1)

Public variable

TArray< int32 >

 

QuadGroups

Group for each quad, ie size = NumQuads (currently all have same value)

Public variable

float

 

UVScaleFactor

Quads on the stitch loop are scaled by this amount
