OpenGL ES Update

Sorry for the silence around here lately.

Unfortunately, the next chapter of OpenGL ES 2.0 I plan to release contains detailed, step-by-step instructions based on Xcode 4 (mostly written around the time of DP2) which is still under NDA. As a result, this chapter is going to take a little longer to scrub, and I haven't had much time to scrub lately.

In the meantime, I realized that I've never linked to the PowerVR Insider SDK, so I'm rectifying that. The company that makes the GPU in all iOS devices has an SDK you can download - in fact, they have several versions of it for different platforms, including iOS. Most of the code is fairly generic C++ with just enough Objective-C around them to work, but there's a metric buttload of good code there for doing all sorts of things. Definitely worth signing and downloading, because they show you how to do a lot of common tasks. It's not very beginner-friendly, granted, but still a great resource you should know about. Most of the code is general OpenGL ES and not actually specific to their hardware, though some of the texture-related tools and optimizations are designed for best performance on their hardware and in some cases use vendor-specific extensions. If you're an iOS-only dev, that's not a problem at all unless Apple changes their GPU vendor.

Thanks for the link, but it looks like the registration page is having problems getting the captcha image. I'll try again later. BTW, thanks for the great articles. I'm looking forward to the next OpenGL post.

Just by way of encouragement: a fantastic chapter 4. Just what I needed to kick me into looking at ES2 rather than ES1, but was previously too scared! Looking forward to the next instalment.
