I am trying to get a SCNVector3 from a CGPoint. I am using a gesture recognizer to get the location of a touch (as a CGPoint). The problem is that the touch doesn't always hit something when I hit test because there isn't always an object being touched. (Touch an empty space to move your ship to that empty spot). Other Stack Overflow question that I have found uses the SCNHitTestResult to get the worldCoordinates but that doesn't work for me. Does anyone know how to find this? Given that I know the z coordinate of course. Ships that move always move with a z position of 1. I Need

I'm trying to animate my model on a SceneKit scene: create a simple cube model and export it to cube.dae create a simple skeleton for cube and make a simple rotation animation using bones and export it to animation.dae using Apple sample Fox demo (WWDC 2015), I tried to put model on scene and it works animate box rotation – it is working but after applying animation, the cube changes its position to (0,0,0) Maybe someone has succeeded with skeletal animation and SceneKit using another 3d tool (Maya, Blender, 3D Max)? to convert .dae to .scn I select DAE file and then in Xcode "editor" -->

I'm tying to create an app with Scene kit to solve Rubix Cube. I've my own dae file for the cube. this is my setup code in viewDidLoad let myscene = SCNScene(named: "Rubik1.scnassets/Rubiks_Cube.dae") scene.rootNode.addChildNode((myscene?.rootNode)!) // retrieve the SCNView let scnView = self.view as! SCNView // set the scene to the view scnView.scene = scene geometryNode = (scnView.scene?.rootNode.childNodeWithName("Cube",recursively: true))! let panRecognizer = UIPanGestureRecognizer(target: self, action: "panGesture:") scnView.addGestureRecognizer(panRecognizer) upon recognising a pan

I read several tutorials how to place 3d objects in SceneKit/ARKit applications and all of them uses .scn format files for the objects. But I found there is no any issues if I use original .dae format and do not convert it to .scn format. I don't really see any difference between .dae and .scn formats. Actually result seems to me the same but can you explain what the difference between them and what I should use in what cases? Thank you! DAE (Digital Asset Exchange, aka Collada) is a vendor-neutral format for 3D assets. It supports a wide range of features that exist in multiple 3D authoring

I'm trying to blur a node or create a blur effect in SceneKit. let ship = scene.rootNode.childNodeWithName("ship", recursively: true)! var ciFilters = [CIFilter]() ciFilters.append(CIFilter(name: "CIGaussianBlur", withInputParameters: [kCIInputRadiusKey: 30])!) ship.filters = ciFilters Results in: Which, I thought ok maybe I'm using the CIFilter incorrectly. However CIHalftone works fine: ciFilters.append(CIFilter(name: "CICMYKHalftone", withInputParameters: ["inputWidth": 20])!) I've also tried with CIZoomBlur also doesn't work, however CIPixellate does. Am I missing something fundamental

I am loading a third-party .dae Collada file as a scene into a SceneKit project. The .dae file has many different animations in it, set at different times/frames. I am trying to figure out how I can split these out and reference each individual animation by reference name. There are no intelligible reference names in the dae file - the animations are all set as one single animation. I am able to parse out the animations into a CAAnimation object, and verify that I have successfully done so with the following code: SCNScene *scene = [SCNScene sceneNamed:@"art.scnassets/man.dae"]; SCNNode *man =
