Variables

Public

Name Type Remarks Include Path Unreal Specifiers
bCrosswiseDiagonal bool Only relevant when CornerInfo is used. CompositionOps/CubeGridBooleanOp.h  
bKeepInputTransform bool When true, mesh is constructed such that ResultTransform is InputTransform. CompositionOps/CubeGridBooleanOp.h  
bSubtract bool Determines whether the box is added or subtracted from the mesh. CompositionOps/CubeGridBooleanOp.h  
bTrackChangedTids bool   CompositionOps/CubeGridBooleanOp.h  
bWorldSpaceUVs bool   CompositionOps/CubeGridBooleanOp.h  
ChangedTids TSharedPtr< TArray< int32 >, ESPMode::ThreadSafe > Will be reset to a container storing tids whose positions or connectivity changed. CompositionOps/CubeGridBooleanOp.h  
CornerInfo TSharedPtr< FCornerInfo >   CompositionOps/CubeGridBooleanOp.h  
FaceUVOrientations TArray< int32, TFixedAllocator< 6 > > For each face of the op box (indexed as in IndexUtil::BoxFaces), determines the orientation in which the UV's should be assigned, which can be imagined as number of counterclockwise rotations of the face in the UV plane while keeping the corner labels the same. CompositionOps/CubeGridBooleanOp.h  
InputMesh TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe > The mesh to add to or subtract from. CompositionOps/CubeGridBooleanOp.h  
InputTransform FTransformSRT3d   CompositionOps/CubeGridBooleanOp.h  
OpMeshHeightUVOffset double When setting UV's on the box, the component affected by height is adjusted by this offset. CompositionOps/CubeGridBooleanOp.h  
OpMeshMaterialID int32 The material ID to give to triangles in the operator mesh. CompositionOps/CubeGridBooleanOp.h  
OpMeshSideGroups TArray< int32, TFixedAllocator< 4 > > Both Input and Output: When not set to InvalidID, these will control the setting of the side groups in the operator mesh. CompositionOps/CubeGridBooleanOp.h  
UVScale float   CompositionOps/CubeGridBooleanOp.h  
WorldBox FOrientedBox3d Box from which to generate the second mesh. CompositionOps/CubeGridBooleanOp.h  

Functions

Public

Overridden from FDynamicMeshOperator

Name Remarks Include Path Unreal Specifiers

virtual void CalculateResult ( FProgressCancel* Progress
)

 Calculate the result of the operator. This will populate the internal Mesh and Transform. CompositionOps/CubeGridBooleanOp.h
