SceneKit project to create 3D logo

This is a demo SceneKit project composed of three elements:

1. outside box (defined via six SCNBox objects per corner and then combining eight corners)
2. inside sun (defined via a SCNTube object for the circle and UIBezierPath objects per "ray")
3. position of camera

Project Structure

• GameViewController.swift
  • initialises the View, Scene and Camera
  • func initScene() calls createBox() and createSun()
• makeCorner.swift
  • makeCorner()
• createBox.swift
  • createBox() calls makeCorner() eight times
• createSun.swift
  • createSun()

Functional as of 11th April 2020

• effectively version 1.0
• code compiles and runs
• sun is correctly positioned inside box
• box is truly cubic
• camera is correctly positioned and allowed to be manipulated
• box spins around the sun based on touch input (random spin, not based on touch vectors)

Development to do

Major

Minor

• add curvature to sun ray sides - they are drawn using UIBezierPath QuadCurves but currently render with straight lines
• rotate each ray fractionally to line up parallel with sun surface
• change materials of cube to be metallic and reflective - really needs new lighting sources to make this work
• embed in SwiftUI view
