Quake releases - vQuake and QuakeWorld
The article will provide a user with information on vQuake and QuakeWorld. These are Quake releases.
VQuake
Let’s have a look at VQuake. In late 1996, id Software released VQuake, a port of the Quake engine to support hardware accelerated rendering on graphics cards using Rendition Vérité chipset. Aside from the expected benefit of improved performance, VQuake offered numerous visual improvements over the original software-rendered Quake. It boasted full 16-bit color, bilinear filtering (reducing pixelation), improved dynamic lighting and even optional anti-aliasing. VQuake was a proprietary port specifically for the Vérité; consumer 3D acceleration was in its infancy at the time, and there was no standard 3D API for the consumer market. After completing VQuake, John Carmack vowed never to write a proprietary port again, citing his frustration with Rendition’s Speedy3D API.
QuakeWorld
Now, let’s have a look at QuakeWorld . QuakeWorld was released in order to improve the quality of online play. It was relased by id Software released on December 17, 1996. It featured significantly revamped network code including the addition of client-side prediction. The original Quake’s network code would not show the player the results of his actions until the server sent back a reply acknowledging them. For example, if the player attempted to move forward, his client would send the request to move forward to the server, and the server would determine whether the client was actually able to move forward or if he ran into an obstacle, such as a wall or another player.
With the help of client-side prediction, which allowed players to see their own movement immediately without waiting for a response from the server, QuakeWorld’s network code allowed players with high-latency connections to control their character’s movement almost as precisely as when playing in single-player mode. The netcode parameters could be adjusted by the user, so that QuakeWorld performed well for users with high and low latency.
The tradeoff to client-side prediction was that sometimes other players or objects would no longer be quite where they had appeared to be, or, in extreme cases, that the player would be pulled back to a previous position when the client received a late reply from the server which overrode movement the client had already previewed; this was known as “warping”. As a result, some serious players, particularly in the USA, still preferred to play online using the original Quake engine (commonly called NetQuake) rather than QuakeWorld. However, the majority of players, especially those on dial-up connections, preferred the newer network model, and QuakeWorld soon became the dominant form of online play. Following the success of QuakeWorld, client-side prediction has become a standard feature of nearly all real-time online games.
As with all other Quake upgrades, QuakeWorld was released as a free, unsupported add-on to the game and was updated numerous times through 1998.
