Book is out :)

You can buy a copy at:

The book comes with all source code that you would need to build applications using OpenGL in Windows, Linux, Mac OS X or Android! I've also put in some effort to link OpenCV and the Android Sensor Manager in Android, and so others who are interested in building interactive application have a simple-to-use code to get started.

With a little bit of hack, you can connect the code base to any depth sensor and OpenCV! That allows you to build lots of applications easily.

Although the book is out, there are still lots I would like to cover, e.g., OpenGL lighting techniques, Compute Shader, and OpenCL/CUDA! Those are super useful for data visualization! and will be covered if there is a great sale to this book this time.

Meta Update & New Book

Augmented Reality eyeglasses is definitely a hot topic these days. At Meta, there are lots of press, and I will start posting ones that I had interview with next.

Also, now my new book is ready for pre-order. You can find the latest work here, especially on the OpenGL + OpenCV side. This book is aimed for beginners who want to know how to get started. I can always answer more difficult problem here if anyone asks.

More to come! Stay tuned...

Through the Glass

Surface tracking based on depth map seems to be robust enough to handle most of the common issues with the color based tracking algorithms. Here is a demo that shows how we can project an image onto 3D seamlessly using OpenGL and our own tracking algorithm.

Paper of course? :)

Hand Tracking (IMPROVED)

Finally fixed some of the issues in the previous hand tracker, and now it works almost as good as the one provided by NITE.

The algorithm is actually very light in resource, and I've already ported it to run on the Android. Stay tuned. =)
