DDDKit

Swift Version Version License Platform

An open source library to support 360 videos and pictures. It's designed as a generic 3D library that you can use for much more!

Example of use cases

  • 360 video player
  • 360 image display
  • generic 3D scene
  • photo / video filters within a 3D scene

Installation

See the wiki! or:

pod 'DDDKit'

Quickstart

import DDDKit
import AVFoundation

class ViewController: DDD360VideoViewController {

  override func viewDidLoad() {
    super.viewDidLoad()
    show(from: myVideoURL)
  }
}

Example

Image filter (easy to be creative!)

// B&W filter:
@IBAction func didPressBW(_ sender: Any) {
  let program = try! DDDShaderProgram(fragment: defaultShader, shaderModifiers: [
    .fragment: "gl_FragColor = vec4(vec3(gl_FragColor.x + gl_FragColor.y + gl_FragColor.z) / 3.0, 1.0);",
  ])
  videoNode.material.shaderProgram = program
}

360 cubic projection

node.geometry = DDDGeometry.Cube()
let videoTexture = DDDVideoTexture(player: player) // AVPlayer with 360 cubic video
node.material.set(
  property: videoTexture,
  for: "SamplerY",
  and: "SamplerUV"
)

Features

  • easy to use syntax and logic
  • support of image and video textures
  • direct and easy access to shader's code, shaders modifiers -> easy to make image filters
  • focus on reliability on video support.
  • equirectangular and cubic 360 support
  • elements that can have any shape / position

Why not SceneKit?

  • SceneKit has bugs, such as memory leaks, failing video support (see SO)
  • no support of AVPlayerLayer / AVPlayer as video input
  • indirect video support (through SpriteKit)
  • openGL backed rendering failing on iOS 10
  • poor documentation
  • unresponsiveness from Apple on issues, and no timeline/transparency on fixes
  • no access to code to fix things yourself, since it's not open source.
