SCNNode is a part of the SceneKit Framework. An SCNNode object represents a portion of a scene graph. A node by itself has no visible content when the scene containing it is rendered—it represents only a position in space (and transformation of coordinate spaces) relative to its parent node. To construct a scene, you use a hierarchy of nodes to create its structure, then add lights, cameras, and geometry to nodes to create visible content.

I have a node that I'm extracting from an SCNScene. I've got some information about it, but I'm confused about one thing - how the bounding box is calculated. The node is positioned once it is loaded at vector 0,0,0 using: [myNode setPosition:…

Avoid 3D nodes to get cut

I'm having a problem with big SCNNodes, they are getting cut like this: How do I avoid this? Is it something to do with the camera? With the SCNView size? With the size of the SCNNode? The SCNNode has this scale: node.scale = SCNVector3Make(100,…

SceneKit – How does the option impulse works for the method applyForce?

When applying a force on a dynamic body, it seems that this force won't be persistent even if impulse is set at false. I have a sphereNode with a physicsBody : dynamic, mass=1 and damping=0. World gravity is set at (0,0,0). If I apply a force in a…

Scale down SCNNode based on its SCNView size or phone screen size

I have a big SCNNode and I want to scale it down. Currently node is scaled down based on a magic number. However the node should be scaled down based on the phone's screen size or node's SCNView size. To make things easier I thought of having a…
