Functions

  Type Name Description
Public function Virtual int32

CreateNewKey ( float KeyIn
)

 Add a new key to the curve with the specified input.
Public function Virtual void

DeleteKey ( int32 KeyIndex
)

 Remove the specified key from the curve. KeyIndex must be within range ie >=0 and < NumKeys.

EvalSub ( int32 SubIndex,
float InVal
)

 Evaluate a subcurve at an arbitary point.
Public function Virtual Const void

GetInRange ( float& MinIn,
float& MaxIn
)

 Get input range of keys. Outside this region curve continues constantly the start/end values.
