scenekit

Have been looking at lighting on Scenekit, and while I can now apply a lighting node to light something I'm looking for a way to light from within an object. As an example imagine a neon glow, or a lightbulb that casts light on other objects. Any ideas how to achieve this? Many thanks. As @DavidRönnqvist hints in comments, there are multiple ways to make an object appear to glow. You can do these together or individually — you'll probably need to tweak how you combine them to get the effect you want. For an object that emits light, you probably don't want shading from other light sources in

I am keen to adopt the new Swift language as this seems to be the way forward with Apple development. I have also been impressed with the new SceneKit support in iOS 8. I would like to programatically create custom geometry at runtime but I am struggling to get the Swift code to work. Yet the equivalent code in Objective C works OK. This could be a bug, or something I am doing wrong. I am simply trying to create and render a single triangle. I will ignore the normals and textures etc at this point for simplicity. So I am only expecting to see a black triangle. Swift Code (not working) var

I've managed to get a cube (SCNNode) placed on a surface where the camera is pointed, however I am finding it very difficult to do the simple (?) task of also placing text in the same position. I've created the SCNText and subsequent SCNNode, however when I add it to the rootNode the text always seems to be added above my head and off the camera to the right (which tells me thats the global origin point). Even when I use the exact same values of position I used for the the cube, the SCNText node still gets placed above my head in the same spot. Apologies if this is a basic question, I've never

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
