Hyperion is a tool designed to help developers and artists quickly create
and prototype realtime 3D solutions: demos, benchmarks, little applications
or games.

Hyperion works a little bit as FireFox or IE: it takes a 3D scene description
code, located in a XML file, and executes it. Really simple!

Hyperion aims to put realtime 3D graphics in everybody's hands by using
a new and very understandable scripting language that will ensure an
efficient understanding of the latest 3D technologies. Hyperion uses
a clever mixture of XML, LUA scripting and GLSL (OpenGL Shading
Language). The underlying 3D engine uses OpenGL for hardware graphics
acceleration.

"features:

Layers

Neon v2 can display up to 10 effects blended each other with
different modes: additive, subtractive, multiply, mask, etc.
Each of them can also have its own filter plus a special layer
to apply a filter to all FX at once.

Output

Output window resolutions from 320x240 up to 1024x768, scalable
to fullscreen with a bilinear filtering when needed. Read manual
in order to setup multimonitor work properly.

Effects

Realtime 3D scenes (through included 3DS Max 7 exporter)
Static Images (JPG, TGA, PNG, TIFF, GIF, BMP, PCX)
.AVI (uses installed codecs)
.MPG,.WMV (through DirectShow, uses installed codecs)
.MPG (through FFMpeg library, uses installed codecs)
.SWF (Beta)
Live Video Captures (Beta)
On screen messages
Post Processing FX

Filters

Filters can be applied to any FX source. Neon v2 filters include
colorize, distort, hi/lo-pass, pixelate, emboss, glow, blur,
halftone, etc. Any user can also program his own filters using
a plain Microsoft .FX effect file based on Pixel Shaders 2.0.

Filter SDK

A filter SDK is available so everyone can code their own
filters, with custom variables added to the GUI easily (slider,
checkbox, combobox, textbox). VC6 C++ basic filter sample
included.

Freeframe

Freeframe support (beta) for all you freeframe filter fans. No
limit for custom variables, they are added runtime as needed."

and the list goes on.

Definately one of my favorites. Its also one of the hardest to
work with without experience, so learn try to get some before
jamming with this bad boy.

VJ is a new developing form of visual expression and performance.
It could be found in clubs, rave parties and art gallerias.
SoYUz is the VJ's best friend for mixing his pre-made video
content on the live set. SoYUz is a "video jockey" mixer for
real time video manipulations in a 3D environment.

Like a DJ turntable, the VJ software mix and layer 2 (or more)
different sources of video to create the "Third Image" a new
image that is existing only in that point of time.

The most basic unit of the visual mix is the movie loop. On
top of that, you can add a live video image into the mix or
sync the video to a sound source.
