Functions

  Type Name Description
Public function Static UDynamicMesh *

ClearPolygroups ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
int ClearValue,
UGeometryScriptDebug* Debug
)

 Resets the triangle PolyGroup assignments within a PolyGroup Layer to the given Clear Value (or 0 if no Clear Value is specified).
Public function Static UDynamicMesh *

ComputePolygroupsFromAngleThreshold ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
float CreaseAngle,
int MinGroupSize,
UGeometryScriptDebug* Debug
)

 Sets PolyGroups by partitioning the mesh based on an edge crease/opening-angle.
Public function Static UDynamicMesh *

ComputePolygroupsFromPolygonDetection ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
bool bRespectUVSeams,
bool bRespectHardNormals,
double QuadAdjacencyWeight,
double QuadMetricClamp,
int MaxSearchRounds,
UGeometryScriptDebug* Debug
)

 Sets PolyGroups by identifying adjacent triangles that form reasonable quads.
Public function Static UDynamicMesh * Creates and assigns a new PolyGroup for each disconnected component of a Mesh.
Public function Static UDynamicMesh * Creates and assigns a new PolyGroup for each disconnected UV island of a Mesh.
Public function Static UDynamicMesh * Copies the triangle PolyGroup assignments from one layer on the Target Mesh to another.
Public function Static UDynamicMesh *

DeleteTrianglesInPolygroup ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
int PolygroupID,
int& NumDeleted,
bool bDeferChangeNotifications,
UGeometryScriptDebug* Debug
)

 Deletes all triangles from the Target Mesh that have a particular PolyGroup ID, in the specific Group Layer.
Public function Static UDynamicMesh * Enables the standard PolyGroup Layer on the Target Mesh.
Public function Static UDynamicMesh * Create list of per-triangle PolyGroup IDs for the PolyGroup in the Mesh
Public function Static UDynamicMesh * Create list of all unique PolyGroup IDs that exist in the PolyGroup Layer in the Mesh
Public function Static int32

GetTrianglePolygroupID ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
int TriangleID,
bool& bIsValidTriangle
)

 Gets the PolyGroup ID associated with the specified Triangle ID and stored in the Group Layer.
Public function Static UDynamicMesh *

GetTrianglesInPolygroup ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
int PolygroupID,
FGeometryScriptIndexList& TriangleIDsOut
)

 Create list of all triangles with the given PolyGroup ID in the given GroupLayer (not necessarily a single connected-component)
Public function Static UDynamicMesh *

SetNumExtendedPolygroupLayers ( UDynamicMesh* TargetMesh,
int NumLayers,
UGeometryScriptDebug* Debug
)

 Sets the number of extended PolyGroup Layers on a Mesh.
Public function Static UDynamicMesh *

SetPolygroupForMeshSelection ( UDynamicMesh* TargetMesh,
FGeometryScriptGroupLayer GroupLayer,
FGeometryScriptMeshSelection Selection,
int& SetPolygroupIDOut,
int SetPolygroupID,
bool bGenerateNewPolygroup,
bool bDeferChangeNotifications
)
