ARKit and Scenekit Utilities

generateNode()

Generates a SCNNode for a SvrfMedia with a type _3d. This method can used to generate the whole 3D model, but is not recommended for face filters.

Declaration

Copy
func generateNode(for media: SvrfMedia,
  onSuccess success: @escaping (_ node: SCNNode) -> Void,
  onFailure failure: Optional<((_ error: SvrfError) -> Void)> = nil)

Parameters

Return Value

On success, it generates and returns a SCNNode from the SvrfMedia provided. The SCNNode can then be added to a SCNView.

generateFaceFilter()

The Svrf API allows you to access all of Svrf's ARKit compatible face filters and stream them directly to your app. Use the generateFaceFilter method to stream a face filter to your app and convert it into a SCNNode in runtime. You can then add the face filter to SceneKit.

Declaration

Copy
func generateFaceFilter(for media: SvrfMedia,
  useOccluder: bool = true,
  onSuccess success: @escaping (_ faceFilter: SvrfFaceFilter) -> Void,
  onFailure failure: Optional<((_ error: SvrfError) -> Void)> = nil)

Parameters

failure | Error closure. -- error | A SvrfError.

Return Value

On success, it generates and returns a SvrfFaceFilter.

SvrfFaceFilter

The class SvrfFaceFilter contains the face filter SCNNode, ability to manage face filter animations, and optional scene overlays.

Declaration

Copy
class SvrfMedia {
  var looping: Bool = true
  var sceneOverlay: SvrfSceneOverlay?
  var node: SCNNode?
  var animations: [(CAAnimation, SCNNode)] = []
  func setBlendShapes(blendShapes: [ARFaceAnchor.BlendShapeLocation: NSNumber]): void
  func animationDidStop(_ animation: CAAnimation, finished flag: Bool): void
  func addAnimation(_ animation: CAAnimation, node: SCNNode): void
}
