Rt-Plot is a tool to generate Cartesian X/Y-plots from scientific data. You can enter and calculate tabular data. View the changing graphs, including linear and non linear regression, interpolation, differentiation and integration, during entering. Rt-Plot enables you to create plots fast and easily. The line calculations give full access to calculation and display ranges and can use statistical weights.
The options can be changed interactively. A powerful reporting module generates ready to publish documents. The result on the screen is the same as on the report printout (what you see is what you get).
Although the program looks simple, the graph can be altered in any item you can imagine. All distances in axis, scaling, numberings, captions colors, line- and point styles and colors can be altered. Thus a plot can be generated fitting the requirements of any journal you want to publish in and of cause your personal taste.

AutoSignal is the first and only program that completely automates the process of analyzing signals. It gives researchers the power to rapidly find components of complex signals that normally require extensive programming and mathematical routines. It takes full advantage of its graphical user intuitive interface to simplify every aspect of operation, from data import to output of results.
AutoRegressive linear models offer robust models that can quickly handle smaller data sets that FFT cannot accurately analyse. With AutoSignal, you can also recover signal components based on power - the component may be sinusoidal, a square wave, a sawtooth or anharmonic pattern. It lets you see a complete picture of the frequency space using the library of six Fourier Spectrum methods with total flexibility. It gives you a choice of three adjustable mother wavelets: Morlet, Paul and Gaussian Derivative - in both real and complex forms to optimise localisation results.
Scientists and engineers can perform complex signal analysis without programming by selecting menu items that determine how the computer will analyze and present data. Selecting a processing step or algorithm causes the software to provide further menus or windows so users can tailor performance to their needs. After the user makes a processing selection, the software immediately presents processing results in 2-D or 3-D views
Built-in spectral analysis procedures include :
FFT
AutoRegressive
Moving Average
ARMA
Complex exponential modeling
Minimum variance methods
Eigen analysis frequency estimation and Wavelets
AutoSignal consists of many important leading edge signal analysis, filtration, prediction, and noise removal technologies.

Mystica is a versatile art generator capable of creating custom images and movies for a variety of projects. Rather than designing standard still images, the program allows you to produce actual artwork. In addition to basic 2D designs, Mystica features a built-in 3D engine. You can render images and movies at any size, export them in all major graphics formats, and let Mystica generate a HTML gallery for you.
3D images are uniquely interactive, and may be explored in real time by means of helicopter, car, virtual camera, or just by walking. The 3D Viewer allows to take screenshots from all perpectives. The underlying 3D engine has the power and complexity of modern game engines and can be used for your own products.
Mystica's 2D editor includes six different freely combinable algorithms, each generating its own image style. You can configure the sequence setting for managing the complexity of your scene. An interesting feature is the Chaos function, which allows you to add "chaotic" structures while preserving the image design. Next, the program provides a complete tool for customizing the color scheme, perhaps to match your web site. There are also sliding scales for mixing linear and exponential colors. Finally, there's a Viewpoint section for navigating through a scene. Multilevel Undo and Snapshot functions as well as editable presets for both image design and coloring guarantee fast explorative results.
The movie generator interpolates between given images. Movies can be exported in all major video formats (divx, mpeg etc) .
Rendering is done fully automated in background. Rendered assets can then be explored in 3D or furtheron edited, e.g. by applying various effects (filters, 3D lighting, layering, coloring etc).
Both the effect and 3D section are also available for images of other sources.
This shareware version is fully functional, but places a watermark on all output. The integrated 3D part is pure fun - a worthwile break for your mind.
