Code With Jim

You will be needing a couple of addons and app: - MIDI input vmpk aka Virtual MIDI Piano Keyboard (or real physical keyboard you can plug into your computer) - AddRoutes - Audio Nodes - Sverchok

Being able to code AR contents and experience very quickly and easily from iPad has always been my dream. Swift Playground app is simply the perfect candidate since we don't have XCode yet on iPadOS but we have this powerful coding app where we can code with Swift and interactively generate 3D Augmented Reality. And that's just one area that can help me to dig deeper into coding programming and eventually making a useful app. AR really presents users with the perfect immersive environment to create an interactive virtual 3D scenes and a lot more that they can simply drop into real life. The limit is only your imaginations. When Swift Playground AR capability paired with other AR app such as Reality Composer to quickly compose 3D scene, attach interactions, audio and behaviour, suddenly you have a very powerful setup for AR. And all can be done via the iPad. We are in luck however; Apparently we can already procedurally generate AR contents and experience since Swift 5.1 ...

This is a quick test to make QR Code Generator that will run on Swift Playground app on iPad. I sourced some of the code online from few forums. The resulting QR Image on "Playground Preview" is stretched, however it seems to still work when I am using iPhone camera to scan it. Ideally the Playground Preview should not be stretched like this and keeping the QR image square. Saving the QR Code itself is another mystery. The whole code is actually very simple, taking advantage of Core Image CIFilter "CIQRCodeGenerator" as below: import Foundation import UIKit import PlaygroundSupport let data = "https://youtube.com/c/jimmygunawan".data(using: .utf8) let filter = CIFilter(name: "CIQRCodeGenerator", withInputParameters: ["inputMessage" : data, "inputCorrectionLevel":"L"]) let ciimage = filter!.outputImage! let transform = CGAffineTransform(scaleX: 20.0, y: 20.0) let image = ciimage.transformed(by: tran...

A few days ago, I found out about "Turi Create" , basically a Python module, a tool from Apple that allows non-Apple computer user to generate MLM aka Machine Learning Model that can be integrated inside iOS app on iPhone and iPad. The cool thing about Turi Create is that you can also use it for your own purpose in processing data using Machine Learning. https://developer.apple.com/videos/play/wwdc2018/712/ As an additional note, at WWDC 2018, Apple also presented XCode Playground tool for MacOS that allows user to easily generate this MLM model for all kind of purposes. The process is as simple as drag and drop for Image Classifier. It is quite fascinating and worth watching the video. STYLE TRANSFER From what I gather after a short research, there are a few applications of Machine Learning that we can use in application such as for Image Classification, Graphing, etc but one that interest me in particular is STYLE TRANSFER using Turi Create: https://apple.gith...

I have a big curiosity on how we can use OSC or MIDI to send message from one app to another app, potentially to generate (realtime) synth sound, visualization, and animation. This is especially a fun area and environment when we wanted to use CODE for CREATIVITY. Sonic Pi (by Sam Aaron) is one app I really love to use when dealing with Synth and Sonic generator. I remember using ChucK in the past by Ge Wang, ChucK is also cool, but Sonic Pi is a lot more friendly. http://sonic-pi.net Sonic Pi multi-threaded ness and LIVE LOOP is really something new for me. But Sam made it easy enough so that we could generate "listener" very easily. MAKING SOUND WITH CODE There are plenty of ways we can "trigger" Sonic Pi to generate sound. Obviously we can just use the built in RUBY language inside Sonic Pi app. Fairly simple and fun language to use and you can generate some noise in no time! Sonic Pi RUBY language documentation is really in depth and a full on progr...
