Functions

  Type Name Description
Protected function Const void

ApplyVertexColorTransform ( FVector4f& Color
)

 Applies an optional sRGB-to-Linear color transform on the input.
Public function void

Convert ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
bool bCopyTangents
)

 Default conversion of DynamicMesh to MeshDescription.
Public function void Internal functions that you can also call directly Ignore any Attributes on input Mesh, calculate per-vertex normals and have MeshDescription compute tangents.
Public function void

Convert_NoSharedInstances ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
bool bCopyTangents
)

 Convert with no shared VertexInstances.
Public function void Convert while minimizing VertexInstance count, IE new VertexInstances are only created if a unique UV or Normal is required.
Protected function void

ConvertPolygroupLayers ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
const TArray< FTriangleID >& IndexToTriangleIDMap
)

 Transfer PolygroupLayers from DynamicMesh AttributeSet to MeshDescription.
Protected function void

ConvertWeightLayers ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
const TArray< FVertexID >& IndexToVertexIDMap
)

 Transfer WeightLayers from DynamicMesh AttributeSet to MeshDescription.
Public function Static bool

HaveMatchingElementCounts ( const FDynamicMesh3* DynamicMesh,
const FMeshDescription* MeshDescription,
bool bVerticesOnly,
bool bAttributesOnly
)

 Checks if element counts match. If false then Update can't be called you must call Convert
Public function bool

HaveMatchingElementCounts ( const FDynamicMesh3* DynamicMesh,
const FMeshDescription* MeshDescription
)

 Checks if element counts match.
Public function void

Update ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
bool bUpdateNormals,
bool bUpdateTangents,
bool bUpdateUVs
)

 Update existing MeshDescription based on DynamicMesh.
Public function void

UpdateAttributes ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
bool bUpdateNormals,
bool bUpdateTangents,
bool bUpdateUVs
)

 Update only attributes, assuming the mesh topology has not changed.
Public function void

UpdateTangents ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut
)

 Use the MeshIn Overlays to update the Tangent and BinormalSign attributes of the MeshDescription, assuming mesh topology has not changed.
Public function void

UpdateTangents ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut,
const UE::Geometry::TMeshTangents< double >* SrcTangents
)

 Use the TMeshTangents to update the Tangent and BinormalSign attributes of the MeshDescription, assuming mesh topology has not changed.
Public function void Updates the given mesh description based conversion options provided in the constructor.
Public function void

UpdateVertexColors ( const FDynamicMesh3* MeshIn,
FMeshDescription& MeshOut
)

 Update only vertex colors, assuming the mesh topology has not changed.
