Syntax
class FMeshSnapOpenBoundaries
Remarks
Similar to FMeshResolveTJunctions, but does not add any vertices to the mesh. Supports running multiple snapping iterations, because snapped-to edges may move in subsequent snaps.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
TSet< int32 > | BoundaryEdges | Subset of mesh boundary edges (otherwise all boundary edges are processed) |
 |
bool | bPreventFlips | Whether to avoid snapping in cases where doing so would locally flip a triangle |
 |
bool | bSnapToEdges | Whether vertices can be snapped to edges; otherwise, vertices are only snapped to other vertices |
 |
double | DistanceTolerance | Distance threshold used for various checks (eg is vertex on edge, end endpoint tolerance, etc) |
 |
int32 | MaxIterations | Maximum number of snapping iterations to perform |
 |
FDynamicMesh3 * | Mesh | The mesh that we are modifying |
 |
int32 | NumVertexSnaps | Number of vertex snaps performed (cumulative over iterations) |
 |
double | VertexSnapToleranceFactor | Scalar multiple of DistanceTolerance at which we snap a vertex directly to another vertex, rather than an edge |
