Classes

Name Remarks
FAttributesSetBase This is the container for all attributes and their arrays.
FAttributesSetEntry This is a wrapper for an allocated attributes array.
FMeshAttributeArraySetBase This is the base class for an attribute array set.
FMeshAttributes  
FMeshConstAttributes  
FMeshElementChannels This is a wrapper for an array of allocated MeshElementContainers.
FMeshElementContainer Class representing a collection of mesh elements, such as vertices or triangles.
FMeshElementIndexer This is an efficient container for holding back references to mesh elements from attributes.
FMeshElementTypeWrapper This is a wrapper for a FMeshElementChannels.
TArrayAttribute Proxy object which fields access to an unbounded array attribute container.
TAttributeArrayContainer  
TAttributesSet This is a version of the attributes set container which accesses elements by typesafe IDs.
TMeshAttributeArrayBase This defines the container used to hold mesh element attributes of a particular name and index.
TMeshAttributeArraySet This is a type-specific attribute array, which is actually instanced in the attribute set.
TMeshAttributesRef This is the class used to access attribute values.
TMeshElementArray We prefer to access elements of the container via strongly-typed IDs.
TMeshElementArrayBase This defines the container used to hold mesh elements.
TMeshElementContainer Templated specialization for type-safety.
TMeshUnboundedAttributeArraySet This is a type-specific attribute array, which is actually instanced in the attribute set.
UMeshDescriptionBase  
UMeshDescriptionBaseBulkData UObject wrapper for FMeshDescriptionBulkData

Structs

Name Remarks
ConstDispatchFunctor  
DispatchFunctor  
FEdgeID  
FElementID  
FElementIDRemappings This is a structure which holds the ID remappings returned by a Compact operation, or passed to a Remap operation.
FMeshDescription  
FMeshDescriptionBulkData Bulk data storage for FMeshDescription
FPolygonGroupID  
FPolygonID  
FTriangleID  
FUVID  
FVertexID  
FVertexInstanceID  
TIsBulkSerializable Traits class to specify which attribute types can be bulk serialized.
TJumpTable We need a mechanism by which we can iterate all items in the attribute map and perform an arbitrary operation on each.
TMeshAttributesRefType  
TMeshAttributesRefTypeBase Define type traits for different kinds of mesh attributes.
TMeshAttributesRegisterType Additional type traits for registering different attributes.
TVariantFromTuple Helper template which generates a TVariant of all supported attribute types.
