GLKit Examples
I've added three new projects to my iOS OpenGL ES repository on GitHub. They are fairly simple examples of how to use GLKit and GLKBaseEffect. You can find them in the GLKit Stuff directory.They're kind of rough, but they should be helpful to you if you're just getting started with GLKit and trying to figure out how to use it.Thanks to Julián Oliver for tweeting the solution to a problem I was having getting textures to work with GLKBaseEffe...

CGAffineTransform Additions
As you probably know, Apple provides a bunch of functionality for manipulating objects in 2D space using CGAffineTransform. Oddly, Apple doesn't provide you with a way to extract the scale, transform, and rotation information from a CGAffineTransform and they don't provide any shearing functionality at all.Here are some additional inline functions that I use. This adds the ability to extract component values of the CGAffineTransform and also adds the ability to create and extract shear information.As always, this code is free to use without restriction or limitation, but has no warranty whatsoever. If you fix a bug, feel free to let me know about the fix so I can incorporate the fix.#ifndef __MCP_AFFINE_TRANSFORM_ADDITIONS__#define __MCP_AFFINE_TRANSFORM_ADDITIONS__#import <CoreGraphics/CoreGraphics.h>#ifdef...

Long Live the King
Jeff Atwood of Coding Horror has an interesting post today about being a developer for Apple's ecosystem. We'll leave aside for now the fact that Jeff isn't and has never been an Apple developer and is, in fact, a strong proponent of Microsoft's developer stack. Despite that flaw, I usually enjoy reading Coding Horror. I think Jeff's a smart guy with a lot to offer the world in terms of insight about software development.But…Jeff's premise today is that third party Apple developers "serve at the pleasure of the king", which is absolutely true. But, he finishes his post by saying he would never develop for Apple's app stores because of the chance of "being thrown under a bus" by Apple. Fair enough, we all have different tolerance levels for things, and his assumption here is essentially correct....

Disappointing
So, like others, I was tempted to write a defense of the iPhone 4S after all the pundits and naysayers came out last week calling the iPhone 4S "disappointing". I'm glad I never found the time. As it turns out the iPhone 4s doesn't need anybody to stand up for it.1,000,000 phones sold on the first day of pre-orders. That's 400,000 more than the iPhone 4. And, that's not counting the number that will sell on October 14th when they arrive at the Apple Stores in 7 countries. There's also a large batch of countries that don't get the phone until October 28, and a whopping 40 more countries (including China, where new Apple Stores have been shattering sales records lately) that won't get the iPhone 4s until some time in December.Yeah. Disappointing. You guys in the media sure nailed that o...

Respect & Shame
It's been fascinating seeing how many people have responded to the death of Steve Jobs exactly the way I did. It's truly amazing how many people who never met the man feel not just that the world has lost somebody significant but that they themselves have lost a friend.Hearing others express exactly what I'm feeling? It helps. And, for the most part, the media has been right there with us, responding to Steve's death by focusing on his impact and the good he has done. I really hope seeing how many peoples' lives he has touched is helping Steve's family and friends get through this.But not all of the media has chosen to focus on the good. I won't link to any of the actual articles, but Gawker and the New York Times top a short list of media outlets that have chosen to focus on Steve's flaws...

Sad Mac
I haven't had much time for blogging lately. I have about a half-dozen unfinished blog posts in my queue, but have been too busy to finish any of them. One of the things keeping me busy right now is work for Apple through MartianCraft. This work, in many ways, is a dream come true for me, as I wanted to work for Apple for years and never managed it. I started programming on an Apple ][+ in 1980 and Apple has been a part of my life ever since then. I don't need to look much further than the desk I'm sitting at to realize just how much my life has been impacted by this company called Apple started in a garage by two guys named Steve. I make a living using Apple's products and developing for Apple's products, but more importantly, my life is better...
