Variables

  Type Name Description
Protected variable TSet< int > BaseBorderE  
Protected variable TSet< int > BaseBorderV  
Protected variable TSet< int > BaseBoundaryE  
Protected variable const FDynamicMesh3 * BaseMesh  
Public variable bool bComputeTriMaps Whether to compute triangle maps (adds additional cost). True by default.
Protected variable FMeshIndexMappings Mappings TODO: this is a fully generic mapping backed by TMaps both ways we could instead back the reverse mapping by a TArray since it's dense for submeshes
Protected variable FDynamicMesh3 Submesh

Functions

  Type Name Description
Public function void

Compute ( const TArrayView< const int >& SubTriangles,
int WantComponents,
bool bAttributes
)

 Computes the Submesh object, index mappings corresponding sub to base mesh, and boundary between sub and base mesh
Public function void

Compute ( FDynamicMesh3* Base,
const TArrayView< const int >& Triangles,
int WantComponents,
bool bAttributes
)

 Computes submesh object, setting a new BaseMesh first
Protected function void

ComputeBoundaryInfo ( const TArrayView< const int >& SubTriangles
)

 Compute boundary vertices and edges between the SubTriangles and the rest of the mesh Called by Compute after the Submesh is computed.
