vz (ViZualizator) Real-Time TV graphics production system

vz (ViZualizator) is software complex for generation realtime TV-graphics. Its based on OpenGL rendering engine that perform rendering target picture in video adapter's framebuffer and block code that transfer framebuffer from videocard to video output adapter's framebuffer.

Rendering objects list is supplied from external file (in XML format). It's tree - based description of graphics primitives layout and operation about parameters changing.

Managing of vz behavior performed by external program that communicate with main rendering module using TCP protocol. Main program provides telnet-like shell where external commands send throw using predefined syntax. Command could be used for loading "scene" file (primitives layout), modification parameters of graphic primitives or for starting/stopping timeline's complex (called director).

Video output provided by professional video adapter (for now it's only [[1]] card tested). Output driver could be written for almost all adapters with open SDK.
