Oh man, I just wasted too many hours of my life trying to figure out why calls to glBlitFramebuffer in my iOS app were returning GL_INVALID_OPERATION. I was targeting iOS 7, so I should’ve been able to use OpenGL ES 3.0 calls, and after all, I’d built against the v3 headers and everything else was […]
On my recent iOS puzzler Wordz, I decided not to reinvent the wheel, and instead use an off-the-shelf 2d game framework. I settled on Cocos2d. It makes it very easy to put together sprite-based games or apps by providing all the basic pieces like a scene graph, animations and integration with a couple of physics […]
Catchy title, eh? This little experiment came about as I’ve been working on an iOS app where I decided to use an embedded OpenGL view, via GLKit, for a bit more flexibility than a plain-old UIView. This found me falling head-first down a rabbit-hole of OpenGL ES shaders. I ended up putting together a little […]
A quick look back at some of the stuff I’ve been doing this year.
Using paths and text to simple create composite animated graphics with Core Graphics, UIKit and Core Animation.
If you know a bit of OpenGL you can integrate the powerful Bullet physics API into your iPad or iPhone app.
A quick look at the physics demo I’ve been writing using Bullet on iOS.
