Simple example usage of OpenGL 4 and vertex array / vertex buffer rendering in a Qt QGLWidget.

Years ago I wanted to implement PTAM. I was young and naïve Well I got a few moments to spare on a recent sleepless night, and I set out to implement the basic bootstrapping step of initializing a map with a planar object - no known markers needed, and then tracking it for augmented reality …
Hi, Just reporting on a small achievement, part of a big project: Creating a browser plugin to display the Kinect depth map on screen. The integration was fairly easy, which leads me to think that both FireBreath and OpenNI/Nite are pretty neat framework that are robust.. So let's see how it's done
How to create a motion-parallax screen using Kinect head tracking. Code in C++, using OpenGL and OpenNI's skeleton model.
Hi, Just wanted to share a bit of code using OpenCV's camera extrinsic parameters recovery, camera position and rotation - solvePnP (or it's C counterpart cvFindExtrinsicCameraParams2). I wanted to get a simple planar object surface recovery for augmented reality, but without using any of the AR libraries, rather dig into some OpenCV and OpenGL code. …
Update: check out my new post about this http://www.morethantechnical.com/2012/10/17/head-pose-estimation-with-opencv-opengl-revisited-w-code/ Hi Just wanted to share a small thing I did with OpenCV - Head Pose Estimation (sometimes known as Gaze Direction Estimation). Many people try to achieve this and there are a ton of papers covering it, including a recent overview of almost all known methods. …
Hi Been working hard at a project for school the past month, implementing one of the more interesting works I've seen in the AR arena: Parallel Tracking and Mapping (PTAM) [PDF]. This is a work by George Klein [homepage] and David Murray from Oxford university, presented in ISMAR 2007. When I first saw it on …
