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.

A Tale in the Desert is a massively multiplayer role-playing game set in ancient Egypt.

It uses the internet to allow thousands of players to play together in the same world. All of the characters you will see and talk to in the game are controlled by other people just like you, not by a computer.

A Tale in the Desert is the first online game to focus on long-term planning and long-term goals rather than combat. Goals include the creation of great works of art and architecture, becoming a powerful leader, and building wealth.

Construction:

Objective: To build a base of operations.

Similarities to: Tropico, Rollercoaster Tycoon, Zeus, Capitalism

Explanation: Your base consists of machines that produce goods, ranging from simple objects like bricks and boards to highly customized goods like gearboxes, mixed paints, and cut gems.

The Challenge: Your base must be designed to operate efficiently and must take into account the values of the goods, supply, and demand.

Puzzles: As you unlock new technologies, you will need to figure out how they work and how you can use them to increase your efficiency.

Trading:

Objective: To make a profit trading goods and services with other players.

Similarities to: Master of Orion 2, Port Royale

Challenge 1: A Tale in the Desert contains too many goods for you to produce everything you need. You must trade to obtain the necessities.

Challenge 2: Learning skills is extremely expensive. To recoup the cost, you must figure out how to hire out your skills to other players.

Puzzles: You must figure out what your goods are worth, and what your time is worth. You must decide whether to give things away freely, and hope for generosity in return, or whether to trade on a more controlled, negotiated basis.

The Tests:

Objective: To increase your powers by performing ritual tests of character.

Similarities to: The multiplayer games you see on Reality TV shows.

The Challenge: There are dozens of different tests, each one a unique ritual that increases your powers. They run the gamut from building a pyramid, to breeding and exhibiting a scarab beetle, to winning a dueling tournament, to searching for hidden altars, to winning an election. They only have one thing in common: they all require you to strategize against other players.

Lawmaking:

Objective: To lift Egypt out of anarchy into true civilization.

The Challenge: A civilization must have rules: rules about who gets to own which piece of land, rules about what kind of pollution is permitted, rules about inappropriate behavior, rules about who gets to benefit from your research labors, rules about who owns which vein of ore. Egyptians must choose these rules for themselves.

The Puzzle: Can you do better than the real governments of today? Can you create a truly fair and just society?
