Hello World SceneKit

In this project I created my first scenekit app, displaying a scene and picking which component i touch. The color of the touched component changes randomly.

Learned about:

Creating sceneKit projects in XCode

To create a sceneKit capable project I had to create a new project in XCode, selecting SceneKit Project. I don’t know, at this moment, it it is possible to add sceneKit later to an existing project.

Creating a Scene in XCode

XCode has a sceneKit scene editor: a simple 3d editor to create things in a scene. No complex manipulations, only spatial placements, light and camera position and materials.

Loading a scene into SCNView

The SCNView is the view responsible to render the scene. You load a scene from the assets and pass it to the SCNView. In my code this is written in the func showMyFirstScene().

Creating animations

When I tap an object I create a SCNTransaction. A transaction takes some time (animationDuration) and interpolates some property to another value during this time. At least that’s how I understood it.
