I'm using Xcode 7.3.1, Swift 2.x, iOS target is 9.3. I can find convenience init init(MDLObject mdlObject: MDLObject) in Apple docs , but I don't see it in my project. I opened standard game project starter, SceneKit is imported. I've tried: Double checking iOS version Adding import ModelIO Finding "mdlObject:" in header files in SceneKit.framework - not found Looking for alternative methods (maybe Apple moved it somewhere) but there are no other inits with that parameter, no class function, nor I found any corresponding export function in MDLObject Cleaning project... I can see all SceneKit

I'm trying to render a 3D model in SceneKit but it looks incorrect. For example this model (it's an SCN file with texture and you can reproduce it in your Xcode): In Xcode Scene Editor it is rendered like this: Transparency -> Mode -> Dual Layer Double Sided = true If I turn off the "Write depth" option, it will look like this: But there are also some issues because it I see only "the lowest layer" of haircut. I think this should be possible. How to do it right? The reason that in your 3D model some strands of hair popped out when viewed from different angles is quite usual for SceneKit: your

According Apple's docs, SCNMaterial.diffuse.contents can be a AVPlayer . In this case material appear content of video. Everything seems ok but I get several sceneKit error logs: [SceneKit] Error: Could not get pixel buffer (CVPixelBufferRef) Below is my code. Move [_player play] to viewWillAppear does't help. - (void)viewDidLoad { [super viewDidLoad]; self.boxNode = [self.sceneView.scene.rootNode childNodeWithName:@"box" recursively:YES]; NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/VRF_SuLie.MP4"]; AVURLAsset *asset = [AVURLAsset assetWithURL:[NSURL

I have several nodes in my scene which i can rotate and drag around. I've set up a physicsWorld delegate, added physicsBody with type kinematic to my nodes and check for physicsWorld didBeginContact - up to this point everything is ok, when i move the nodes , the contact begin/end fires. The way i'm trying to handle this is to set a bool var that change to true once the contact start to prevent further movement, but i'm running into cases (especialy if i drag the node too fast) , that the node gets a little bit inside of the other object. should i use different approach to this? I don't really

I am going through some SceneKit concepts and one I am trying to solidify in my head is unprojectPoint. I understand that the function will take a point in 2D and return a point in 3D (so one with the proper Z value). When I read the documentation I read this: /*! @method unprojectPoint @abstract Unprojects a screenspace 2D point with depth info using the receiver's current point of view and viewport. @param point The screenspace position to be unprojected. @discussion A point whose z component is 0 (resp. 1) is unprojected on the near (resp. far) clip plane. */ public func unprojectPoint(_

First, before I go on, I have read through: SceneKit painting on texture with texture coordinates which seems to suggest I'm on the right track. I have a complex SCNGeometry representing a hexasphere. It's rendering really well, and with a full 60fps on all of my test devices. At the moment, all of the hexagons are being rendered with a single material, because, as I understand it, every SCNMaterial I add to my geometry adds another draw call, which I can't afford. Ultimately, I want to be able to color each of the almost 10,000 hexagons individually, so adding another material for each one is
