Functions

  Type Name Description
Public function void

AppendMesh ( FDynamicMesh3& AppendTo,
const FTransformSequence3d& TransformSeq
)

 Append the geometry represented by this wrapper to the accumulated AppendTo mesh, under the given world transform
Public function bool

Build ( const FMeshSceneAdapterBuildOptions& BuildOptions
)

 If possible, spatial data structure should defer construction until this function, which will be called off the game thread (in ParallelFor)
Public function void

CollectSeedPoints ( TArray< FVector3d >& WorldPoints,
TFunctionRef< FVector3d(const FVector3d&)> LocalToWorldFunc
)

 Collect a set of seed points from this Mesh, mapped through LocalToWorldFunc to world space.
Public function double

FastWindingNumber ( const FVector3d& P,
const FTransformSequence3d& LocalToWorldTransform
)

 Calculate the mesh winding number at the given Position.
Public function Const FIndex3i

GetTriangle ( int32 TriId
)

  
Public function Const int32  
Public function FAxisAlignedBox3d

GetWorldBounds ( TFunctionRef< FVector3d(const FVector3d&)> LocalToWorldFunc
)

 Calculate bounding box for this Mesh
Public function Const bool  
Public function Const bool

HasUVs ( int UVLayer
)

  
Public function Const bool

IsTriangle ( int32 TriId
)

  
Public function bool

ProcessVerticesInWorld ( TFunctionRef< bool(const FVector3d&)> ProcessFunc,
const FTransformSequence3d& LocalToWorldTransform
)

 Apply ProcessFunc to each vertex in world space.
Public function bool

RayIntersection ( const FRay3d& WorldRay,
const FTransformSequence3d& LocalToWorldTransform,
FMeshSceneRayHit& WorldHitResultOut
)

 Find the nearest ray-intersection with the mesh. Must be callable in parallel from any thread.
Public function Const bool

TriBaryInterpolateNormal ( int32 TriId,
const FVector3d& BaryCoords,
FVector3f& NormalOut
)

 Compute the barycentric interpolated normal for the given tri
Public function Const FVector3d

TriBaryInterpolatePoint ( int32 TriId,
const FVector3d& BaryCoords
)

 Compute the barycentric interpolated normal for the given tri
Public function Const bool

TriBaryInterpolateUV ( int32 TriId,
const FVector3d& BaryCoords,
int UVLayer,
FVector2f& UVOut
)

 Compute the barycentric interpolated UV for the given tri
