0.0: Swift OpenGL Setup

To follow along with these tutorials, you'll need a Mac with the latest public version of Xcode (Xcode 6.4 as of this writing).  To get Xcode, open the App Store and search for Xcode. 



You'll see a bunch of applications, but Xcode should be the first one if you typed in "xcode" into the search field.  I already have the application downloaded, so the button says "Open", but if you haven't downloaded Xcode, the button will say "Get".



You may be prompted to input your AppleID and password and click "Buy".  Remember, the app is free.  The app will download automatically when you "Buy" the app.  Once it has downloaded, you'll find it in your Applications folder, Launchpad, or by holding down ⌘ and pressing the spacebar you'll get Spotlight Search where you can type in "xcode" and press return on the keyboard.



The first time you open Xcode, you should see the splash screen.  This is a great starting point to create new projects or open existing and recent projects.  Create a new project by clicking on "Create New Project" (I've blurred out my previous projects, but you would see your previous project at the right of the welcome screen).  While in Xcode, you may open the Welcome Screen at any time by pressing ⇧⌘1 on the keyboard.


The page down menu prompts you to select the type of project to create.  On the left side of the menu, select Application under OS X.  Then select Cocoa Application from from the icons at the left.  Click next.  You'll be prompted for a name, company, etc.  The name of our project is SwiftOpenGL.  Leave the Organization name field blank for now.  For Organization Identifier, you have to put something, so it nothing is there, insert "com".  Click on the language dropdown menu and select Swift if it is not selected already.  Finally, make sure Use Storyboards is checked and Create Document-Based Application and Use Core Data are not checked.


Click next and you'll be asked for a location to save the project and related files.  I recommend using the Developer folder that should have been created when you downloaded Xcode.  You should be able to find it by click on the dropdown menu at the top of the menu and click on Macintosh HD.



Select the Developer folder, and click Create.  A whirlwind of computer magic will ensue and you'll be presented with your first Xcode app!  At the top left of the screen, you'll see a play button icon.  This is the Run button.  Click Run and you're application will build and launch.  It's not exciting--just a grey window--but it'll let you know that you have a working application.



Now that we have a working app, we need to add a view to our window that will display out OpenGL content.  Continue to 0.1: The SwiftOpenGLView

4.0.0: MVC OpenGL Part 1

Image
Thinking in MVC Thus far, all of our code has been living in the view.  This was helpful for a time so we could see how the individual pieces of OpenGL interact in the simplest way possible; however, there is a limit to the readability and modularity of this C-like paradigm.  To fix this, we'll refactor the graphic engine into separate pieces in a way that conforms, as best we can, with Apple's MVC app design. Start by creating a new target--completely new.  Click on the SwiftOpenGL project in the Project Navigator.  In the Editor view, beneath all of the targets listed, click on the “+“.  Name the new target OpenGLMVCPt1.  Copy the ViewController.swift and SwiftOpenGLView.swift code into new versions of these files as we have done before (remembering to adjust the compile sources so that the new versions are used instead of those from OnTheMove).  This time, however, we’re going to call the view controller SwiftOpenGLViewController because we want to show that this co

Using Swift with OpenGL

Image
Programming with Mac has changed a lot since the introduction of Swift to the platform.  It's a great language that has grown so much since its conception a year ago.  The tendency is to continue to use old paradigms with new tools; however, Swift is so different from C and Obj-C.  It demands that we rethink how we program on the Mac so we aren't limiting the potential of this new language. With those ideas in mind, I have endeavored to rethink OpenGL programming in terms of using Swift.  Classically a C++ dominated topic, graphics programming in Swift offers some interesting twists this programming genre.  Though there are some great tutorials for using OpenGL in a Swift project, most of them do not utilize some of the new Swift paradigms (namely protocols, extensions, and more value types instead of reference types).  I am not an expert or even professional programmer by any means, but the tutorials that I shall write here work and are intended to be in line (as much as
