Hey guys! Just updated my earlier blog post on creating Augmented Reality (AR) on iPhones using the new iOS4.0 features. I’ve also moved away from the 'UIGetScreenImage' function as it’s no longer supported. Now, we access the camera using the AV Foundation framework with the help of AVCaptureSession. As always, you're free to download and fiddle with my code available in this blog. Happy Programming!

As I strove to learn OpenGLES 2.0 for new gaming projects on iPhone and Palm Pre, I faced certain challenges due to the introduction of a programmable graphics pipeline in OpenGLES 2.0. With this mechanism, we are responsible for writing the code to generate our graphics, which was overwhelming at first. To help others, I ported some of the NeHe tutorials over to OpenGLES2.0 on iPhone in an easily-digestible way. In this post, you will find a walkthrough of the first 4 tutorials, complete with codes, explanations and screenshots to make learning easier.

This tutorial guides you through applying textures to a rotating 3D cube using OpenGL. We will be utilizing the esUtils code, specifically its function esGenCube, and modify our shaders to accommodate our texture coordinates. After setting up our new mvp matrix and position vertex attribute, we will apply a texture to our rotating cube. The code can be found via a provided link.

I've made a triumphant return to the blogosphere with the release of my new game, 'Tanks!' developed for Palm Pre/Pixie and soon for iPhone devices. The game, an experiment to learn OpenGLES 2.0, is a testament to the feasibility of porting C++ or C code from iOS to Palm PDK, despite minor challenges with UI interaction and audio. So gear up, folks! Download 'Tanks!', step onto the battlefield and let the mayhem begin! Next stop on my coding odyssey - Android!

In this blog post, I delve into the specifics of porting code for drawing 3D shapes in ES2.0. I detail how to overcome the lack of depth buffer in the default OpenGL template and describe how to add rotation to objects by saving the model view matrix. This post offers a useful walkthrough, especially for those keen to deepen their understanding of 3D rendering nuances in ES2.0.

I'm thrilled to have introduced my first 3D game on the app store. The entire process served as a real learning curve, with some elements still appearing obscure, yet adding to the intrigue. The games section of the app store is known for its fierce competition, but challenging the status quo by doing something different from the regular utility apps is quite a welcome change. I'm generally proud of how the game has turned out and look forward to its reception. You can download the game on the app store.

Had a laugh this morning at the Apple store on Regent Street with an iPad owner who doesn't know what to do with his shiny new toy, and a confused cyclist who was convinced only a celebrity could draw such a crowd! Certainly a morning for the books.

Hey there, just a quick update to let you know I've whipped up a new demo using the RSS feeds from the iPlayer site. It locates URLs and takes advantage of the webview to play the movies out, pretty neat huh? Just a reminder, you'll need the iPhone SDK and tool chain to get this project up and running, and remember, it's a rough around the edges, so use with caution. Be sure to check out the original blog post for more insight. Just a heads up, don't expect to see this app on the iTunes store anytime soon, the...

Just got an iPad from the US, thinking it'd be perfect for BBC iPlayer. To my dismay, the website needed flash to play anything! Weirdly, iPhones can run it, so I'm trying to trick the iPad iPlayer website into thinking my iPad is an iPhone. It involves setting a User-Agent and using some simple code to change 'embed' tags to HTML5 video tags. Works pretty fine so far, even with full screen video and device rotation. Just needs some tidying up. Although I believe BBC will eventually update their code for the iPad, we're allowed some hacks in the meantime....

Just gave a enlightening talk on Box2D at the LiDG and have prepared a step-by-step walkthrough on creating a simple pinball game using the open sourced 2D physics engine! You'll learn the concepts of Body, Shape, Friction, etc. as well as how to build and run the Box2D engine for iPhone. By the end of the blog, you'll be equipped to create a basic working game in a couple of 100 lines of code! Don't forget to check out my slides and demos linked in the blog!

Here's the concept: your iPhones turn into wireless controllers and your tablet is now your console, all thanks to gamekit. It's a whole new way of gaming, reminiscent of the Wii, or using your devices for interactive card games. Interesting eh?

In this blog, I explain the process behind my Sudoku Grab app, a solution that uses basic image processing techniques to recognize Sudoku puzzles. This is done by locating the puzzle in an image, turning it back into a square form, segmenting it to find potential numbers, and lastly, recognizing those numbers. This involves simple thresholding techniques, blob extraction algorithm, perspective transform, and a Neural Network for Optical Character Recognition (OCR) to recognize digits from the photograph. I conclude by mentioning the potential for multiple enhancements to this process.

Apologies for the radio silence on sales stats for our app, but to be fair, there hasn't been much spark! After the US App Store feature, it was a sliding game down the charts, but still, we average about 10-30 copies daily. We excitedly crossed the 25,000 download mark recently. Oh, and there's a chart you can find below with more deets. A Dutch website brought a brief sales soar, but that's died down now. All told, we've clocked in 25591 paid and 8436 free downloads, the latter gaining a brief spotlight during a celebratory two-week freebie phase. Sure seems...

I'm thrilled to announce that Sudoku Grab has reached 25000 downloads! As a token of gratitude, the app will be available for free until the 25th June. A huge thank you to everyone who has purchased the app and for all the valuable feedback.

I'm off to San Francisco this Sunday for the Apple's WWDC event. I'm anticipating it will provide a lot of valuable insights for potential future enhancements.
