Syntax

class FCubeGridBooleanOp : public UE::Geometry::FDynamicMeshOperator

Remarks

Operator meant to be used with UCubeGridTool that adds or subtracts a box to/from an input mesh, with options to weld the box's corners to make ramps/corners

Variables

Type	Name	Description
bool	bCrosswiseDiagonal	Only relevant when CornerInfo is used.
bool	bKeepInputTransform	When true, mesh is constructed such that ResultTransform is InputTransform.
bool	bSubtract	Determines whether the box is added or subtracted from the mesh.
bool	bTrackChangedTids
bool	bWorldSpaceUVs
TSharedPtr< TArray< int32 >, ESPMode::ThreadSafe >	ChangedTids	Will be reset to a container storing tids whose positions or connectivity changed.
TSharedPtr< FCornerInfo >	CornerInfo
TArray< int32, TFixedAllocator< 6 > >	FaceUVOrientations	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.
TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe >	InputMesh	The mesh to add to or subtract from.
FTransformSRT3d	InputTransform
double	OpMeshHeightUVOffset	When setting UV's on the box, the component affected by height is adjusted by this offset.
int32	OpMeshMaterialID	The material ID to give to triangles in the operator mesh.
TArray< int32, TFixedAllocator< 4 > >	OpMeshSideGroups	Both Input and Output: When not set to InvalidID, these will control the setting of the side groups in the operator mesh.
float	UVScale
FOrientedBox3d	WorldBox	Box from which to generate the second mesh.
