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

So, been working hard on my projects, and discovered some interesting things in Android possibilities for frame animation. Last time I was using an HTML approach, because of memory consumption issues with using ImageViews. However now my approach is using View.onDraw(Canvas) to draw BMPs straight off files, in an asynchronous way, and it seems to …
Hi, Just a quicky about OpenCV and Windows Presentation Framework interoperability. It's really easy with a simple Managed C++ wrapper. What I'll show is how to transfer an OpenCV cv::Mat into WPF's BitmapSource. Let's see how it's done.
Hi, I'll present a quick and simple implementation of image recoloring, in fact more like color transfer between images, using OpenCV in C++ environment. The basis of the algorithm is learning the source color distribution with a GMM using EM, and then applying changes to the target color distribution. It's fairly easy to implement with …
Switching, merging or swapping, call it what you like - it's a pain to pull off. You need to spend a lot of time tuning the colors, blending the edges and smudging to get a decent result. So I wrote a plugin for the wonderful GIMP program that helps this process. The merge is done …
Hi The graphics course I took at TAU really expanded my knowledge of 3D rendering, and specifically using OpenGL to do so. The final task of the course, aside from the exam, was to write a 3D game. We were given 3 choices for types of games: worms-like, xonix-like and lightcycle-like. We chose to write …
Hi I recently did a small project combining a Java web service with a OpenCV processing. I tried to transfer the picture from Java environment (as BufferedImage) to OpenCV (IplImage) as seamlessly as possible. This proved a but tricky, especially the Java part where you need to create your own buffer for the image, but …
