inline

Member Function Documentation

Cut()

bool FMeshSelfCut::Cut

(

const MeshIntersection::FIntersectionsQueryResult &

Intersections

)

Split mesh along the provided intersections

Parameters

Intersections

A set of mesh intersections, for example as returned by TMeshAABBTree3::FindAllSelfIntersections

ResetOutputs()

void UE::Geometry::FMeshSelfCut::ResetOutputs ( )

inline

Validate()

EOperationValidationResult UE::Geometry::FMeshSelfCut::Validate ( )

inline

Returns

EOperationValidationResult::Ok if we can apply operation, or error code if we cannot

Member Data Documentation

bCutCoplanar

bool UE::Geometry::FMeshSelfCut::bCutCoplanar = false

If true, detect coplanar faces and re-triangulate so that the triangulations match 1:1 (TODO: not implemented!)

bTrackInsertedVertices

bool UE::Geometry::FMeshSelfCut::bTrackInsertedVertices = false

If true, record vertex insertions

Mesh

FDynamicMesh3* UE::Geometry::FMeshSelfCut::Mesh

Mesh to cut – note that FMeshSelfCut::Cut is destructive, so this are an output

SnapTolerance

double UE::Geometry::FMeshSelfCut::SnapTolerance = FMathf::ZeroTolerance * 100.0

Tolerance distance for considering a point to be on a vertex, edge or plane

VertexChains

TArray<int> UE::Geometry::FMeshSelfCut::VertexChains

Outputs Packed chains of vertex IDs, representing the vertices for each segment in the mesh Packed as the number of vertices in that chain, followed by that many vertex ids, per segment NOT 1:1 w/ segments; some segments may have failed to insert

Empty if bTrackInsertedVertices == false
