![]() The NDS Association member companies decided to develop a data conversion tool for OpenDRIVE to support simulation activities of its members. Image source: Wikipedia OpenDRIVE and NDS The result is a precise 3-dimensional road definition. The basic principle for describing a road segment in OpenDRIVE is to first define a reference line (aka anchor line or road center line) and then attach various attributes to it. The data may be derived from manually created road networks, conversion of real-world map data, or data collected of real-world roads. Dynamic entities like cars, bikes, or pedestrians are not included. The data describes the exact road geometry, including surface properties, markings, signposting, and logical properties such as lane types and directions. Unlike other file formats, the description is typically used for simulation applications. Its main goal is the facilitation of data exchange between different driving simulators. The OpenDRIVE data format specification contains definitions for all static objects of a road network that allow realistic simulation of vehicles driving on roads. This is where the ASAM OpenDRIVE specification comes into play. Now, this can mean that engineers drive around in cars adorned with roughly hewn sheets of metal, or camouflaged with fancy swirls in black and white, but more often, it comes down to simulations – and lots of it. But before any car can hit the road, it needs to be thoroughly tested for all eventualities. In the last blog articles of our “Data for all” series, we’ve looked at standards that define how different, navigation-related kinds of data can be shared on the road – between vehicles, amongst ECUs or sensors, or with different manufacturers, suppliers, data providers or authorities. Some of the more exotic stages involve the player summoning an army of antlions to unleash on unsuspecting foes.Data for all: Simulating logical road networks with OpenDRIVE 22. A few levels require the player to navigate buggy-type vehicles. Setpieces in the game include co-ordinated assaults on enemy bases, fighting gigantic boss enemies, bringing down aircrafts with the rocket launcher, and others. ![]() One of the most notable weapons is the gravity gun, with which Gordon can pick up objects, hold them in the gun's anti-gravity field, then hurl them at the enemy with great force. To defend himself, Gordon has a range of weapons available: from the iconic crowbar for close-quarter fighting, through pistols and rifles, up to grenades and a rocket launcher. Policemen and foot soldiers work along with helicopters, gunships and gigantic walking machines to hunt him down. Gordon's enemies, apart from alien wildlife which found its way to Earth, are mainly Combine forces, which utilize a variety of firearms, gadgets and vehicles. The game features a realistic physics system: Gordon can pick up objects and toss them freely, and many of the puzzles are physics-based - for example, at one point the player has to weigh down a seesaw with bricks at one end to turn it into a ramp. On his way, he'll encounter a few friendly characters, but also fight dangerous foes. The player guides Gordon Freeman through the City 17 and the wilderness that surrounds it. Half-Life 2 is a linear first-person shooter with light puzzle-solving elements and many setpieces, similar to its predecessor in concept. Gordon is soon brought into a resistance group, and makes a seemingly futile attempt to bring down the Combine and liberate the Earth. Meanwhile, Gordon Freeman, the man who was at the center of the events that took place shortly before the rise of the Combine, awakens from his stasis and is inserted into a train to City 17 by the mysterious G-man. Earth is turning into a grim, oppressive police state. An energy field prevents humans from procreating, and no new children are born. Wallace Breen, a human scientist, rules the city on behalf of his new masters. A Combine Citadel is erected in City 17, a town in Eastern Europe reminiscent of World War II ghettos.
