The Open Source Artzy™ Camera is an ARKit super-starter project created by Delasign that features an AR multi-media recorder, 3 AR samples, a library of free metal shaders and special effects, illustrator and maya files.
If you create anything, please share it on Instagram and tag @artzyapp along with #artzy.
Download the repo and print the three images in the "GettingStarted" folder. These are the three AR samples that come with the project.
After printing, open the app and place your phone infront of the images to experience the three samples.
I recommend reading up on AR and ARKit before becoming familiar with how the samples were created. These are found in the "HowItWasMade" folder, which includes the files that were used and the corresponding images.
If you have any questions please email questions to : artzy@delasign.com

This project features a double neon glow - the word glows in blue, whilst the halo glows in red.
For tutorials on how this was created please read the following:
Geometry:
- How to use an Adobe Illustrator Curve in Maya.
- How to turn a turn a simple sketch into an extruded model on Maya
- UV Mapping: How to Convert an Extruded Cylinder’s UV’s to Simple Layout
Neon:
- Apple Documentation : SCNTechnique
- ARKit Theory: Intro to SCNTechniques.
- How to create a glowing neon effect for a geometry in ARKit through a SCN Technique
- A SCNTechnique requires a .scn model
Code:
The key parts to this working are found in PieceOfArtzy/PieceOfArtzy.swift line 182 -> 264, with the SCNTechnique and associated assets under the PieceOfArtzy/SpecialEffects/GlowInTwoColors folder.
Extra: To see it perform an animated, timed stroke - switch the functionality in PieceOfArtzy/PieceOfArtzy.swift line 34.
This project features a 3d stroke neon glow - it appears as though the word has been drawn.

- A SCNTechnique requires a .scn model
Stroke: The key parts to this working are found in PieceOfArtzy/PieceOfArtzy.swift line 66 -> 92. The amount of the letter that must be shown at any given instance has to be programmed in order for the camera to be able to capture it. For a non-capturable version and how to take it from there to the latest version, please read:
Code:
The key parts to this working are found in PieceOfArtzy/PieceOfArtzy.swift line 264 -> 312, with the SCNTechnique and associated assets under the PieceOfArtzy/SpecialEffects/Glow folder.
This project features an outline of a hand that animates to show you the peace sign.
