Demos related to OpenGL, Qt/QML, OpenCV and other X technologies.

Demo	Description	Screenshot
cvDisplacementMapFilter	Displacement Map Filter implementation in C++/OpenCV that renders two images as a movie clip.
cvFruitClassification	C++/OpenCV port of a cool Python application that performs Oranges vs Apples classification using LDA.
cvQtImage	C++/OpenCV/Qt example that displays an image and the RGB values of a pixel based on mouse coordinates.
cvQtCameraGL	An interesting demo that shows how to use C++/OpenCV to retrieve frames from the camera and draw them with Qt QGLWidget for GPU rendering (OpenGL).
cvQtVideo	Another C++/OpenCV/Qt example on how to display video files with configurable Aspect Ratio.
cvWatershedSegmentation	Stackoverflow answer that uses C++/OpenCV's watershed segmentation with distance transform to segment beans.
ipcQtGesture	C++/Qt application that uses the old Intel® Perceptual Computing SDK 2013 for gesture recognition. Windows only.	No image available
qml2DRaycasting	QML implementation of 2D raycasting.
qml2DRaycastingEngine	QML implementation of a 2D raycasting engine.
qml2DQuadTree	QML implementation and visualization of the data structure Quadtree that offers operations to insert new points and search them within a rectangular area.
qml3DTerrain	Qt3D/QML implementation of dynamic terrain generation based on Perlin noise.
qmlBattery	A Qt/QML element that displays the amount of energy left in a Battery as horizontal bars according to the charge. For demonstration purposes, the charge value is set dynamically and randomly from the C++ side.
qt3DRenderer	A complete 3D Graphics Renderer that demonstrates how to load simple meshes from Wavefront files (with texture) and performs all the required transformations to project them on a 2D color buffer that is copied into a QImage object to be displayed with Qt.
qtArduinoSerial	A simple C++/Qt example on how to print data from a serial (COM) port connected to Arduino.	No image available
qtFPSvsTIMEAnimation	Super educational C++/Qt implementation of FPS-based and Time-based animation techniques, as explained by Steven Lambert.
qtGLMdemo	A customized QGLWidget that loads a 3D model from the disk using Nate Robins GLM library and renders it using native OpenGL calls.
qtKinectVideo	C++/Qt application based on Color Basics from Kinect for Windows SDK 1.8. This demo displays the Color Stream of the camera.	No image available
qtLinearRegressionGD	C++/Qt/Eigen implementation of Linear Regression based on Daniel Shiffman's tutorials. Data is plotted with Madplotlib (Qt required).
qtLogoBlurGL	A silly C++/Qt/OpenGL demo that renders a logo on a texture and displays a glow around it.
qtSmoothColorTransition	A C++/Qt application that takes a grayscale image and performs a smooth color transition using a predefined color palette based on linear interpolation.
