Super Mixer is a project I started in summer 2009 to experiment with OpenGL for the real-time mixing of several videos. In short, it is a ’V-Jeying’ program for mixing many video files in life performances.
I won’t enter into too much details because I want to keep some ideas in a corder before eventually releasing/publishing them. I can however present the general idea; each video is a layer (a-la photoshop) and its transparency and blending options can be altered in real time. OpenGL makes (...)
The CREATE USB Interface (or CUI board) is made and produced by Dan Overholt (AAU, DK). It is IMO a good alternative to the more famous and more industrial Arduino, and I had the opportunity to play a bit with it.
Anyway, the point is the following:
CUI boards are provided as HID usb devices, so, reading data from them means reading a HID device.
The little source provided here just does that for Linux! : CUIReader
Warning; this is not a specific driver for the CUI board, this is not (...)
This short document explains how to program with OpenSceneGraph in order to control objects or the camera from external tracking. These are however general guidelines which can be used for programming many things. I present how to create an OSG node callback, how to connect to a remove VRPN tracker, and how to create a custom camera manipulator.
Visiting a node during update
Given that you have a ref to a node in the scenegraph;
You want to move it at every (...)
