Vamos Automotive Simulator / News: Recent posts

Version 0.8.1 - Configuration Fixes

I recently switched from Gentoo to Debian. (Gentoo's great, it's just more hands-on than I want to be sometimes.) Well, I ran into some trouble trying to build Vamos. This release should make the configure script more portable. Even so, there are a few things that may not be automatic on some systems. So I'll show the steps I went through to get everything building and running.

I installed wheezy and then switched to the testing distribution. I installed
- libsdl-dev
- libopenal-dev
- libalut-dev
- freeglut3-dev
- libboost-all-dev
- python3-dev... read more

Version 0.8.0 - Pythonified!

The main application is now a Python 3 program. The C++ simulation code is wrapped into modules by Boost.Python, so there's no loss of performance. This is intended to be a first step toward a friendlier game-like interface.

Other changes include better robot behavior, especially when passing; the ability to qualify and race against robot cars; tire heating; and improved randomly-generated tracks.

Vamos 0.7.1 is Released

Functionality has been added to make the main program more like a racing game. The computer-controlled cars can now pass and be passed reasonably gracefully. Sets of F1 and GT cars are provided with varying appearance and performance characteristics. The running order, time intervals, and lap count shown on screen. Performance of the robot cars can be adjusted from the command line to match your opponents to your skill level.... read more

Vamos is now in Git

The official code repository is now in Git. You can get it with
git clone git:// vamos-git

The CVS repository is no longer maintained. It'll remain stuck a some point after the 0.7.0 release.

Vamos 0.7.0 is out

The latest release includes improvements to the computer-controlled cars. They handle just about any track without tweaking. They even account for humps, dips, and banking when deciding how fast to go and when to brake. They can be pretty stiff competition. The control algorithms are documented in detail.

Vamos 0.6.3 Is Out

Robot drivers now try to avoid collisions. Heavily used vector functions were inlined to improve performance. Bumpy surfaces are more realistic. Timing inaccuracies have been fixed. A sound for riding kerbs has been added. The map view now has keys for zooming and panning. Several new tracks have been added: Yas Marnia, Monza with banked oval, Valencia, Singapore, Jerez, and the new Silverstone layout.

Vamos 0.6.2 Is Out

The performance of robot cars is greatly improved in this release. I wouldn't say they're unbeatable, but I can't keep up on most tracks. Added "--demo" or "-d" option in case you want to ride along with a robot. Try "vamos -d -c F1 -t Spa" for a fun ride.

Aerodynamic forces are now reduced when driving in another car's slipstream. The density of the air is reduced, resulting in decreased drag and downforce, when a car is where another car has recently been.... read more

Vamos 0.6.0 is released

A new release of Vamos Automotive Simulator is available. Vamos is an automotive simulation framework with an emphasis on thorough physical
modeling and good C++ design. Vamos includes a real-time, first-person, 3D driving application.

Support for pit lanes is now provided. Collisions with the ends of the pit wall are detected. Bugs in the general handling of collisions have been fixed. Another bug that caused the wheels to stop spinning when they leave the ground was also fixed. One symptom of this problem was loss of control when hitting the kerbs in the F1 car.... read more

Vamos 0.5.7 Is Out

This version uses SDL for graphics and input handling and OpenAL for audio. The user-visible changes are an optional full-screen mode and audio effects like doppler shift and distance attenuation.

If you're using the code, please note that the locations of some files have changed.

Vamos 0.5.6 Is Out

Version 0.5.6 has a few bug fixes and some progress on pit lanes. Silverstone, Imola, Albert Park, Interlagos, Laguna Seca, Bahrain, and Spa tracks have been updated.

This release is a checkpoint before I start doing some maintenance of the design.

Vamos 0.5.5 Is Out

Handling has been improved by changing the way that lateral and longitudinal forces are combined. Camber forces are now handled correctly. Cars can be set to shift to neutral instead of stalling. Engine torque curves may be specified by a set of control points.
Preliminary support for pit lanes has been added. Skew calculations have been fixed and documented.

Vamos 0.5.4 Is Out

Rendering of sharp turns can be improved by providing a "skew" parameter in the track definition file. Rear views are now rendered while panning. Cars are reloaded without losing textures or affecting frame rate. Multiple cameras can be specified in the track definition files. Definition files outside of the installation directories can be specified on the command line by giving full path names.

Posted by Sam Varner 2005-07-01

Vamos 0.5.3 Is Out

This release includes optimizations for faster startup and, when multiple cars are used, higher frame rates. The Istanbul grand prix curcuit has been added. Support for CppUnit tests has been added.

If you have CppUnit on your system the tests will be built and run unless you disable them at configure time. Right now there are only a few tests, but there will be more in future releases.

Vamos 0.4.0 Is Out

The main reason for incrementing the middle number is that all of the XML definition files are now in place. In addition, the Silverstone, Magny-Cours, and Nurbergring tracks were updated, and Monza was added. Braking markers (signs that show the distance to a curve) were added. Wing behavior was improved. The main branch of LibSigC++ is now used. A customizable system was put in place to handle keyboard and joystick input. Documentation was updated.
