" VVVV" is a toolkit for real-time video composition, providing a graphical programming language for easy prototyping and development, designed to make it easier to manipulate large media environments by means of physical interfaces, real-time video, audio and video that can interact with many users at the same time.

1. Use the spread to easily handle a large number of objects: vvvv can handle a large number of objects at once, whether they are graphics or data, without the user having to make a particularly significant effort to do so. There is no significant difference in the user interface between controlling a single instance of a graphical object with vvvv and 1000 instances, which we call "spreading".

We sometimes want to assign different values to each individual in a group of objects, and spreading is an abstraction of this behavior. Setting up a table is like distributing plates at a dinner table, where they have different positions. vvvv includes a number of spreading generators to make it easier to write complex behaviors for a large set of objects.

2. Using Boygroup's seamless multi-projector technology:

There are many applications that require the use of several PCs to achieve the desired number of output screens/projections, and controlling these PCs individually It's easy to mess things up by controlling these PCs individually. Instead, vvvv allows us to easily control any number of client computers from a single server using Boygrouping technology.

Boygroup allows us to easily build multi-screen systems or seamless multi-screen projections. It allows us to build rendering clusters where we can individually pick and choose which nodes to run on the server and which to run on the client. It allows us to control which data needs to be transferred over the network and which is more appropriate to be computationally derived on all the clients, a capability that allows us to manually optimize a setup without much magic.

3. 3D rendering based on DirectX:

vvvv's 3D engine is based on Microsoft's DirectX technology. DirectX is a set of APIs (Application Programming Interfaces) for high performance computing. By leveraging the power of modern graphics cards, DirectX allows vvvv's rendering performance to approach that of computer games.

DirectX terminology was maintained as much as possible when translating DirectX features into vvvv's graphics programming interface. This makes it easy for people familiar with DirectX programming to understand the substance underneath this veneer.

4. Loading 3D models:

Although vvvv has nodes for creating, calculating, or modifying geometric data, it should not be viewed as a 3D modeling tool. The proper way to get an existing object moving is to import a model with textures using DirectX's own .x format file, which is supported by almost all major 3-D modeling software. In addition to importing models,

vvvv provides standard geometry such as quadrilaterals, grids, cubes, spheres, and of course teapots.

5. Texturing of 3D models using dynamic graphics or images:

There is a large range of options for using textures in vvvv. In addition to traditional still images (such as bmp, targa, png, dds, etc.), vvvv can use image files, camera inputs, or flash movies as mapping for any 3D object. Even a part of the desktop can be used as a texture, and the texture can be generated in real time from any data in a patch.

6. Real-time shading programming:

vvvv's pixel and vertex shading allows users to accomplish more than the usual visual representation of a 3d appearance. Shaders allow you to run programs on the graphics card, and shaders make it clear how the graphics card resolves each 3d vertex sent to it, what calculations are loaded on it, and how the color of each pixel is derived.

7. Real-time physics simulation:

vvvv contains ODE by Russel Smith, a set of open-source, high-performance library functions that can be used to simulate rigid body dynamics (collision detection with friction). (collision detection with friction), ODE is useful in simulating vehicles, objects in virtual reality environments, virtual organisms, and many other applications.

8. Real-time video analysis:

The video analysis node is implemented through the freeframe plugin system, so it can be developed independently from vvvv. Some nodes have been implemented with a number of different tracking techniques. Such as: contour capture, color capture, motion detection, etc.. If this is not enough, you can always develop custom freeframe plugins.

9. Audio features:

vvvv's sound engine is based on Microsoft's DirectShow technology and is capable of playing most formats of audio files as well as doing simple mixing of multiple audio files (as long as these files are The vvvv sound engine is based on Microsoft's DirectShow technology and is capable of playing most formats of audio files as well as simple mixing of multiple audio files (as long as they are playable in Windows Mediaplayer).

All input devices with WDM drivers (also called multichannel devices) can work with vvvv. A very interesting thing for many people is to analyze the input sound, there are several ways to get the volume of each channel or through the FFT (Fourier Transformation) algorithm to get the volume of different frequencies.

10. The ability to interact with a wide variety of external devices and protocols:

vvvv has the ability to control a wide variety of third party devices such as DVD players, industrial interfaces (for lighting and electrical), touch screens, gaming devices, turntables, positioning and directional sensors, MIDI devices, DMX interfaces, serial interfaces, keyboards, and mice.

In addition to the underlying protocols such as TCP, UDP and RS232 for communication with other computers or software, the high level nodes allow communication via MIDI, DMX, ArNet, OSC, HTTP and IRC.

VVVV is a hybrid graphical and text programming language environment for easy prototyping and development, designed to facilitate the handling of large multimedia environments and physical interfaces more easily. This includes real-time motion graphics, audio and video capabilities that can interact with many users simultaneously. It features real time, many other languages with many different modes of programming and operation, and can be used for non-commercial applications at no cost.

vvvv is suitable for many contexts, including common computer-related media such as audio, video, 3D animation, the Internet, and so on, just to name a few particularly popular ones. In addition to creating and converting for these media, vvvv is also easy to develop the ability to accept a variety of inputs and generate outputs for a variety of external devices.
