WeatherMasters game purpose is to build a rainbow across all the sky while cleaning the landscape from raindrops and thereby scattering the clouds.

A game includes 50 levels and combines unsophisticated, classic, easy-to-learn game play and an original action.

Mastering the game is facilitated by prompts. The game provides for bonuses that make a playing process varied and unforeseeable.

Not everybody is endowed with the ability to set fine weather, to scatter the clouds, to build a rainbow. You will be given such a chance in our game. It is not so easy, especially at first (as the weather gets better, it is easier to build a rainbow). Only those daring and decisive will set about it and when they manage to succeed they will be rewarded by the beauty appearing before them.

The beautiful landscape is saddened only by the gloomy cloud from where multicolored drops fall now and then. Drops fall on the land and remain there in layers.

Silent Wings Simulator game is a highly realistic flight simulator, designed to give high training value for soaring pilots as well as great fun for everyone interested in flight simulation.

The dynamic behavior is based on accurate models from computational aerodynamics, and new techniques for terrain modeling support sceneries of virtually unlimited size and detail.

Learn how to keep control during extreme maneuvers or climb the thermals into the fully volumetric cumulus clouds. Experience the excitement of low altitude hang-flying along spectacular mountain ridges, or simply load a GPS log to replay your own or your fellow pilot’s real life flight.

Aerodynamics

The aerodynamics in the simulator is governed by true physical principles in that the force field acting on the glider is computed from local air flow over the wing profiles as well as position and movement of the control surfaces (elevator, aileron, rudder). The force field is represented by a multitude of local force vectors giving rise to correct behavior, even in “asymmetric situations” like for example side-slip, stall, aero towing and entrance into thermals.

Sceneries

The sceneries in Silent Wings are based on a breakthrough in level-of-detail (LOD) technology that integrates triangulated topographic models, terrain textures, linear features and physical objects in a unified framework geared towards real time visualization. This technology scales almost perfectly with data sizes and allows in principle any resolution for real time rendering.

Weather

The weather model is constructed through realistic simulation of the physical systems for thermals and wind layers. Thermals are based on ground heat capacity models deduced from spectral analysis of certain satellite images. With this as a basis the complete thermal cycle, including rise of warm air, build-up of cumulus clouds, inflow of cool air, and evaporation of the cumulus clouds, is simulated to give high visual and physical realism.

In fact, the user can judge ground, wind and cloud characteristics in the same way as he does during real physical soaring, and find that the atmospheric properties behave as he would expect.

Aircraft

Silent Wings contains 4 flyable aircraft ranging from the sturdy G-103 Twin II trainer to the open class Antares self-launcher. All aircraft have animated moving parts and fully functional 3D cockpits. The wings are flexing naturally in respons to the aerodynamic situation.

The current library of aircraft is planned to be extended, not only with sailplanes, but also other types of flying vehichles.

DB Visual ARCHITECT (DB-VA) offers software developers an excellent solution for database applications development. DB Visual ARCHITECT is an Object-Relational Mapping tool which provides an easy-to-use environment bridging between object model, data model and relational database.
DB-VA not only empowers you the visual modeling capability for performing both logical and physical data design, but also automates the roundtrip mapping between object model and data model.
Developers save enormous amounts of time using DB-VA to manage the coding of SQL and JDBC transparently with Plain Old Java Objects (POJO), as DB Visual ARCHITECT empowers software designers to perform roundtrip engineering of a relational database into a Class Diagram, and to an Entity Relationship Diagram and vise versa. Likewise designers can also create a database from entity relational models or class models visually on the fly.
DB-VA also generates a cost-effective, reliable, scalable and high-performance object to relational mapping layer. The generated mapping layer includes the support of transaction, cache and other optimized features. DB-VA increases the productivity and significantly reduces the risks of developing the relational mapping layer manually.
Main features:
Automate the Mapping Between Java Objects to RDBMS Tables
DB Visual ARCHITECT helps mapping between Java objects to relational database. This act not only preserves the data, but also the state, foreign/primary key mapping, difference in data type and business logic. Developers are no longer necessary to handle those tedious tasks.
Re-engineering Application Based on Legacy Database
DB Visual ARCHITECT allows you to reverse database (DB Reverse) tables through JDBC into UML models. You can form Class Diagram from the reversed models and redesign the legacy database without pain.
Multiple Database Support
DB Visual ARCHITECT promote easy migration between databases by enabling the same set of ORM Java objects to serve different databases. Besides, the tool help transforming proprietary data-type into one that suit the default database which is specified by user.
Well Proven Visual Modeling Technology
DB Visual ARCHITECT inherits the visual modeling environment from Visual Paradigm for UML, a well-known UML CASE Tool that provides intuitive inline editing for both Class Diagram and ERD. This truly what-you-see-is-what-you-get diagram editing facility reduces the effort and time in design the system.
Enhancements:
- Branch and tag capabilities were added to the VP Teamwork Server, including Subversion and CVS repository integration.
- This allows different modeling projects to be run in parallel while keeping the release quality project stable in the trunk.
- There were also a number of enhancements for various other features.

Gamma Patrol project is an old style, vertical scrolling space shooter.

You have to fight your way through lots of enemies using different kinds of weapon systems.

The game was intended to be my first Linux program, but I had to switch to Win95 for a while, because the harddisk with Linux fucked up. Now - with a brand new K6-2 500MHz - development is continued under Linux again.

Gamma Patrol is built on top of the Simple DirectMedia Layer (SDL), a platform independent API for games. My primary target platform is Linux, but Im able to supply Windows and BeOS versions, too. Thanks to SDL and GCC this is just a matter of ./configure && make

The game features quite nice looking graphics - almost everything has been rendered with the PoVRay raytracer. Title and background music is still to be composed, my wife just began to play with a tracker...
