Congratulatory Note On Engagement

physical model of the tires

The tires have a key role in the dynamics of a vehicle through them we have the vehicle's interaction with the asphalt, and are home to all the main forces exchanged with it. In literature, many physical models have been proposed for them, but for our purpose realtime simulation we have identified these possible candidates:

• model Pacejka
  
• brush model
• spring model

The first is the most widely used by most current simulations, is an empirical model based on experimental observations of some correlations between the quantities characterizing the behavior of a gomma.E 'based on' approximated curves of some of the tire behavior (such as lateral force / slip angle) by interpolation. The coefficients of interpolating polynomials are obtained by means of "magic formulas" from some physical parameters. The advantage is that at runtime everything is reduced to a simple lookup in a table, because the job of calculating the coefficients can be easily done offline and store the in all pre-calculated tables.

The last two models attempt to explain the physical phenomenon of the adhesion rubber-asphalt and calculate the forces at play. In fact, you must divide the tire sectors (or segments) and apply the formulas to each of them. From the standpoint of use in real-time are much heavier than Pacejka, in fact every frame must calculate all the forces and iterate this calculation for each area. But to simulate some important aspects such as elastic deformation of the shoulder of the tire, the temperature distribution on the tread, etc ...

How Tight Is Tight Bolt

circuit wanted. . .

For the first test of Engine chart urge to have a 3D model of a circuit well done. Thus we turn to the Italian community in many modders simracing: there would be enough permission to use within a circuit Oversteer already made (perhaps in the form of rFactor, etc.).

to take this opportunity to reiterate that we are always looking for a 3D model of circuits for the creation of dedicated circuits to Oversteer.

hope of finding a great help, waiting for your proposals.

Force Feedback

From the partial results of the survey show that, so far, the most desirable features is the force feedback. As our knowledge on this subject are quite limited, we support you all.

What are the physical laws that govern it?
How does it interface with the engine peripherals? Would
manual or automatic setting of its parameters?

The staff is expanding!

As you can see from the box, the technical staff of the project expands. Offers are coming together by all parties. Today we have added Alessandro Castellini, a mechanical engineer in Milan as a consultant for the physical Pierluigi Nastasi, student of Information Science of Catania as a model of car, and finally Mirco Dondolini , 23-year-old Tuscan great sim racing expert, as a tester across the board. Congratulations to our new employees from the staff.
invitation to all lovers of Italian racing sim: help with the project according to your ability and skills! We make a concerted effort to create the best Italian sim!

Open a forum on DrivingItalia

Thanks to the support offered by the portal DrivingItalia, we have a forum dedicated to the project. Three sections were created:

1. Technical choices: we will discuss the pros and cons of various solutions implemented
2. Physics: vehicle dynamics will be discussed and formulas related
3. Wishlist : This section was created with the aim of identifying innovative and original features that differentiate Oversteer by existing simulators.

A special thanks to Nicola "Velocipede" Trivilino, director and founder of DrivingItalia, which made this possible.
We expect many on the forum, to grow together this project.

What's The Symptomoflupus

Minimal

Being a "garage" game, developed in his spare time, you can not expect to have the wealth functionality of commercial games. For the first release I decided to focus on a minimum set of features that distinguish it as a realistic driving simulation, with advanced graphics and advanced physics. The project must be very flexible so you can add more functionality over time, and other categories of cars.
Analyzing the main driving simulators, I have identified the essential characteristics for Oversteer:

hardware / software platforms:

• Windows XP / Vista : DirectX 9.0c, XNA Framework, video card with Shader Model 2.0 or higher.
• XBox360 with XNA Game Launcher installed.
  

Gameplay:

• track type: street circuits
  
• Type of car: wheel covers, car
  
• Game Mode: private tests, single race, championship
• Choice of sessions (practice, qualifying, race)
• Setup editable

Graphics:

• Normal mapping for all objects of the circuit
• Offset mapping to emphasize the importance of the curbs
• Environment mapping for car bodies
• with HDR and dynamic lighting effects "bloom"
  
• Soft shadows
• lens flare effect when you have the sun in front of the tires on the asphalt tracks

Sound:

• engine sounds pre-recorded

Physics:

• Aerodynamics : simulation of the downforce of the wings and ground effect, the wake effect.
• frame: the moment of inertia about three axes, anti-roll bars.
• Suspension: double wishbone. Adjustable shock absorbers and springs.
  
• Tires: Pacejka model-like, temperature, pressure and wear variables dynamically
• Transmission: rear-wheel drive with limited slip differential adjustable

Artificial Intelligence:

• configurable number of opponents
• pilots to defend the position that
  
• possible errors of pilots to

Genesis of Oversteer Oversteer

As a child, playing with the first game for the legendary Commodore 64, I dreamed of becoming a game programmer, then the cases of life and environmental conditions (low sw-house distribution of video games in Italy), led to deal with boring business software. But I continue to cultivate this passion and chase this dream. So far they have managed to achieve only incomplete demo, but from the Microsoft XNA framework I started to believe in the possibility of creating a "garage game".
This library allows the programmer to focus on the amateur specific aspects of your game, avoid spending time putting up the infrastructure, just think of the ease of importing graphics and sound files allowed by the Content Pipeline. Also I have been fascinated by the idea of \u200b\u200bbeing able to schedule a next-generation consoles like Xbox 360 and it is amazing how easily you can deploy and debug a project on the X360. The main objection that many people make is that the use of an interpreted language such as C # is a limit to performance, but in fact the largest computational load in the modern game you have for graphics and this is now almost entirely drawn from the GPU via shaders, so C # is no longer a big problem. For me, that I came from years of programming C and C + +, C # was a discovery pleasant, really construct a very powerful and convenient as the region, the delegates also allows you to use threads so easy, this is a card winner of the XNA framework because all the new CPUs are multicore (XGPU can process the 6 hardware threads simultaneously). A further push towards the choice of XNA came to learn that, in early 2008, Microsoft will launch a YouTube-like site, which will serve as a showcase for amateur games created with XNA. I think it's important to have a minimum visibility for your game, also the best video games published by Microsoft itself will be on XBox360 Live Arcade Marketplace. Also with version 2.0 of XNA, which is available at Christmas, it will also support multiplayer network, making it really completes the platform.
Choosing the technology, I had to decide the type of game to be created, I have decided to make a game that I would have liked to play, rather than deciding based on commercial grounds and fashions. Have always been fond of car racing and F1, and my favorite video games are always been the driving simulators and therefore the choice fell on this type. Also because there were some good examples of games created by amateur projects of one to two people and become a commercial reality: see example of Italian or the Dutch Netke Live for Speed, the game you intend to inspire me, however, is R- Factor, for its versatility and modifiability. Other sources of inspiration were the driving realism of Forza Motorsport 2 and clean graphics and lighting of Gran Turismo 4 and 5. It 'clear that for an amateur project is impossible to reach the technical level of the games mentioned as well as implement all their features. So I decided to focus on a subset Feature of that for me are the essence of a driving simulator: a photo-realistic graphics and physics very realistic. Much of the preparatory work for this game was to study the dynamics of the vehicle: I bought 3 different books, including the "Bible" of the race engineers, "Racecar Vehicle Dynamics" by Milliken & Milliken.
