Functions

  Type Name Description
Public function Static UDynamicMesh * Builds a Bounding Volume Hierarchy (BVH) object for a mesh that can be used with multiple spatial queries.
Public function Static UDynamicMesh * Finds the nearest point (Nearest Result) on the Target Mesh to a given 3D point (Query Point) by using the Query BVH.
Public function Static UDynamicMesh * Finds the nearest intersection of a 3D ray with the mesh by using the Query BVH.
Public function Static UDynamicMesh *

IsBVHValidForMesh ( UDynamicMesh* TargetMesh,
const FGeometryScriptDynamicMeshBVH& TestBVH,
bool& bIsValid,
UGeometryScriptDebug* Debug
)

 Checks if the provided Bounding Volume Hierarchy (BVH) can still be used with the Mesh — it generally returns false if the mesh has been changed.
Public function Static UDynamicMesh *

IsPointInsideMesh ( UDynamicMesh* TargetMesh,
const FGeometryScriptDynamicMeshBVH& QueryBVH,
FVector QueryPoint,
FGeometryScriptSpatialQueryOptions Options,
bool& bIsInside,
EGeometryScriptContainmentOutcomePins& Outcome,
UGeometryScriptDebug* Debug
)

 Tests if a point is inside the mesh using the Fast Winding Number query and data stored in the BVH.
Public function Static UDynamicMesh *

RebuildBVHForMesh ( UDynamicMesh* TargetMesh,
FGeometryScriptDynamicMeshBVH& UpdateBVH,
bool bOnlyIfInvalid,
UGeometryScriptDebug* Debug
)

 Rebuilds the Bounding Volume Hierarchy (BVH) for the mesh in-place, which can reduce memory allocations, compared to building a new BVH.
Public function Static UFunction BlueprintCallable, Category, Meta void Reset the Bounding Volume Hierarchy (BVH) by clearing all the internal data.
Public function Static UDynamicMesh *

SelectMeshElementsInBoxWithBVH ( UDynamicMesh* TargetMesh,
const FGeometryScriptDynamicMeshBVH& QueryBVH,
FBox QueryBox,
FGeometryScriptSpatialQueryOptions Options,
FGeometryScriptMeshSelection& Selection,
EGeometryScriptMeshSelectionType SelectionType,
int MinNumTrianglePoints,
UGeometryScriptDebug* Debug
)

 Create Mesh Selection of mesh elements in TargetMesh contained by QueryBox, using QueryBVH to accellerate the computation.
