scnnode

Trying to figure out how I create a SCNGeometry with polygon as primitiveType, My goal is to add polygon shaped node as a child of a sphere node, and make it look like MKPolygon for map kit, like in this example . My current code is: //Take an arbitrary array of vectors let vertices: [SCNVector3] = [ SCNVector3Make(-0.1304485, 0.551937, 0.8236193), SCNVector3Make(0.01393811, 0.601815, 0.7985139), SCNVector3Make(0.2971005, 0.5591929, 0.7739732), SCNVector3Make(0.4516893, 0.5150381, 0.7285002), SCNVector3Make(0.4629132, 0.4383712, 0.7704169), SCNVector3Make(0.1333823, 0.5224985, 0.8421428),

I'm new to iOS development and I've got myself stumped. I am trying to render a cube using SceneKit that has a different colour for each face. This is what I've got so far: func sceneSetup() { // 1 let scene = SCNScene() // 2 let BoxGeometry = SCNBox(width: 0.9, height: 0.9, length: 0.9, chamferRadius: 0.0) BoxGeometry.firstMaterial?.diffuse.contents = UIColor.redColor() let cube = SCNNode(geometry: BoxGeometry) cube.position = SCNVector3(x: 0, y: 0, z: -1) scene.rootNode.addChildNode(cube) // 3 sceneView.scene = scene sceneView.autoenablesDefaultLighting = true sceneView.allowsCameraControl =

I am trying to replicate this cube image shape (with permission from the original creator ) using scene kit. Thus far, I have the drawing code for the lines and the vertices. I cannot use an image because the background has to be transparent. The specific I am trying to solve right now is how to edit the stroke width for the SCNGeometryPrimitiveType.Line element. The basic way I am creating lines is like this: private func squareVertices(length: Float) -> [SCNVector3] { let m = length/Float(2) let topLeft = SCNVector3Make(-m-q, m+q, m+q) let topRight = SCNVector3Make( m+q, m+q, m+q) let

It's 360 degree video player project. I add a cameranode( SCNNode ) to a rootnode, the cameranode was put at the center(0,0,0) of the SCNSphere , It can play video by now. Now I have to use devicemotion. I need to rotate the camera when device moves. Not just rotate a certain angle. (Not just device move, When I'm holding a device, my moving regard as the device moving. because I found if I use deviceMotion.attitude.roll , the cameranode only moves when device moves by itself, not when I circle around with device) When device is located in (x1,y1,z1) position, the cameranode would rotate as
