Tutorial: How To Quickly Create High Performance Image Filters With GPUImage

Some time ago I mentioned the excellent GPUImage library that eliminates the need for most of the OpenGL ES 2.0 boilerplate code making image and video filters easier on the iOS platform.

Apple made it much easier to create image filters with Core Image, but there are tremendous speed gains to be had by using OpenGL ES 2.0 directly.

Jake Gundersen who created the excellent iOS Core Image section in the iOS 5 By Tutorials book has created an in-depth step-by-step tutorial on how to use GPUImage to create a complex video tutorial.

Here’s a video demonstrating the filter you’ll create with the tutorial:

Definitely a huge time savings by using GPUImage over coding OpenGL ES 2.0 shaders without GPUImage.
