Classes

  Type Name Description
Public struct FCompressedRichCurve A runtime optimized representation of a FRichCurve.  
Public struct FCurveAtlasColorAdjustments    
Public struct FCurveAttributes Structure allowing external curve data to express extended attributes  
Public class FCurveOwnerInterface Interface you implement if you want the CurveEditor to be able to edit curves on you.  
Public struct FIndexedCurve A curve base class which enables key handles to index lookups.  
Public struct FIntegralCurve An integral curve, which holds the key time and the key value  
Public struct FIntegralKey An integral key, which holds the key time and the key value  
Public struct FKeyHandle Key handles are used to keep a handle to a key. They are completely transient.  
Public struct FKeyHandleLookupTable Lookup table that maps key handles to indices in an external data structure Maintains a map of key handle to last known index, and an array of optional key handles that's used to validate map entries.  
Public struct FKeyHandleMap Represents a mapping of key handles to key index that may be serialized  
Public struct FNameCurve Implements a curve of FNames.  
Public struct FNameCurveKey One key in a curve of FNames.  
Public struct FRealCurve A rich, editable float curve  
Public struct FRichCurve A rich, editable float curve  
Public struct FRichCurveEditInfoTemplate Info about a curve to be edited.  
Public struct FRichCurveKey One key in a rich, editable float curve  
Public struct FRuntimeCurveLinearColor    
Public struct FRuntimeFloatCurve    
Public struct FRuntimeVectorCurve    
Public struct FSimpleCurve A rich, editable float curve  
Public struct FSimpleCurveKey One key in a rich, editable float curve  
Public struct FStringCurve Implements a curve of FStrings.  
Public struct FStringCurveKey One key in a curve of FStrings.  
Public class IKeyFrameManipulator Templated key frame manipulator that knows how to add, remove and (re)arrange key times.  
Public class TKeyFrameManipulator Templated key frame manipulator that knows how to add, remove and (re)arrange key times.  
Public struct TKeyTimeIterator Key time iterator for TKeyFrameManipulator  
Public class UCurveBase Copyright Epic Games, Inc.  
Public class UCurveFloat    
Public class UCurveLinearColor    
Public class UCurveLinearColorAtlas Manages gradient LUT textures for registered actors and assigns them to the corresponding materials on the actor  
Public class UCurveVector    
Public class UDEPRECATED_CurveEdPresetCurve CurveEdPresetCurve A preset curve data object  

Functions

  Type Name Description
Public function CurveValueType

UE::Curves::BezierInterp ( CurveValueType P0,
CurveValueType P1,
CurveValueType P2,
CurveValueType P3,
float Alpha
)

 Assuming that P0, P1, P2 and P3 are sequential control points of an N=4 Bezier curve, returns the interpolated value for interpolation constant Alpha in [0, 1]
