ScientificVR (SVR) is a software package for visualization of complicated physical-chemical processes numerical simulation results as well as 3D distributions obtained from other sources, for example, results of tomography. The package has a flexible plug-in architecture, and its possibilities can be easely expanded by means of developing corresponding plug-in by user or by GDT Software Group at client's request.
The package features are:
- 3D voxel graphics: SVR is able to visualize function distribution in a 3D domain by means of setting color and transparency of each domain point depending on function value in this pount. Color and transparency dependance on fuction value is set by means of a color-transparency palette adjusted by a user;
- stereoscopic 3D presentation: SVR allows users to view stereoscopic presentation of functions 3D distributions;
- creating animation files: SVR allows users to view both the dynamic process as it progresses and static distributions from different viewing angles by means of creating and viewing dynamic and rotating animations;
- friendly and intuitive GUI: this makes users' work and education process fast and easy;
- on-the-fly visualization: SVR provides on-the-fly data visualization when it visualizes GDT package computation results;
- unrestricted combination of different image presentation types: users can combine different data presentation types, for example isosurfaces and stremlines, and/or use different color paletts for different parts of the image.
Output formats
ScientificVR allows to save images in the most of the best known graphic formats:
- Windows Bitmap (BMP);
- Portable Network Graphics (PNG)
- Tag Image File Format (TIFF)
- Joint Photographic Experts Group File Interchange format (JPEG)
- Encapsulated Postscript format (EPS)
- other graphic formats (it depends on the type of the installed plugins)
Images can also be printed out.
Types of data presentation
- Graphs
This way of presentation of one-dimensional scalar quantities is one of the easiest and most convenient.
- Color presentation of 2-dimensional scalar data
This pictorial and efficient way of presenting 2-dimensional distribution of a scalar quantity on the computer screen is accomplished by means of coloring the domain points with a certain color, corresponding to the value of the parameter in question. The user can set up the color palette himself.
- Height presentation of 2-dimensional scalar data
Another way of presenting 2-dimensional distribution of a scalar quantity consists in drawing such a 3D surface, the first two point coordinates of which correspond to the point coordinates of a 2-dimensional domain, and the third coordinate is proportionate to the scalar quantity in question.
- Isolines
Very often it turns out to be convenient to present distribution of a 2-dimensional parameter with the help of isolines. Their color may be assigned by a value of a certain preset parameter.
- 2- and 3- dimensional vectors
To visualize 2- and 3-dimensional vector fields the user has to draw vectors in the points, located at fixed distances from one another. Vector depths can be either equal or proportionate to vector depths of the field. Vector colors may represent the values of the parameter indicated by the user in points where these vectors are drawn.
- 3-dimensional voxel graphics
For the presentation of distribution of 3-dimensional parameters a special technique has been designed, based on voxel graphics and the use of translucent palettes.
- Isosurfaces
Isosurfaces are similar to isolines, but are meant for visualizing 3-dimensional fields. The color of isosurfaces depends on the value of the parameter.
- Composite displays
The above mentioned types of data presentation can be easily combined, which allows to carry out multifactor qualitative analysis of the phenomenon.
- Тextures
The distribution of the parameter over any surface can be represented with the help of textures.
- Streamlines and tracers
Streamlines provide important information about the structure of vector fields. Streamlines may be represented in a number of different ways: by means of lines, belts, tracers of flow, "optical disc", etc.
- Animation
3-dimensional animation allows to gain more information about a certain process or phenomenon. Videos can be saved in the AVI format using different compression setups (depending on the types of endecs installed in the system).
- Stereo-images
One of the most important capabilities of the ScientificVR® visualizer is that of generating and showing stereo-images on ordinary personal computers. To see the stereoeffect, the user has to use conformable video display card and stereo glasses (for example, ASUS V7100 Deluxe).
