vertex(_:at:ofPath:at:)

Declaration

func vertex(_ vertex: UnsafeMutablePointer<FxVertex>!, at index: Int, ofPath pathID: FxPathID!, at time: CMTime) throws

Parameters

• vertex:

  A pointer to an FxVertex structure to hold the information about the vertex in question.

• index:

  The index of the vertex you want to retrieve. This is 0-based, so if the path has n vertices, this will be between 0 and n-1.

• pathID:

  The ID of the path from which you wish to retrieve a vertex.

• time:

  The time at which to retrieve the vertex information.
