Xonotic
''Xonotic'' () is a free and open-source first-person shooter video game. It was developed as a fork of'' Nexuiz'', following controversy surrounding the game's development. The game runs on a heavily modified version of the Quake engine known as the DarkPlaces engine. Its gameplay is inspired by ''Unreal Tournament'' and '' Quake'', but with various unique elements. Gameplay There are sixteen different game modes in ''Xonotic'', including classic modes like deathmatch and capture the flag. In order to unlock more game modes, players must complete different levels of gameplay. To score points, players must kill enemies using futuristic weapons while completing objectives. The gameplay is very fast-paced, due to players being able to move at high speed and jump erratically. While the basic concept is inspired by other games of the same genre, there are several unique elements. Emphasis is placed on movement and player physics, with a focus on gaining speed, jumping great di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DarkPlaces Engine
The ''Quake'' engine is the game engine developed by id Software to power their 1996 video game '' Quake''. It featured true 3D real-time rendering and is now licensed under the terms of GNU General Public License v2.0 or later. After release, it immediately forked, as did the level design. Much of the engine remained in ''Quake II'' and ''Quake III Arena''. The ''Quake'' engine, like the ''Doom'' engine, used binary space partitioning (BSP) to optimise the world rendering. The ''Quake'' engine also used Gouraud shading for moving objects, and a static lightmap for nonmoving objects. Historically, the ''Quake'' engine has been treated as a separate engine from its successor, the ''Quake II'' engine. However, both engines are now considered variants of id Tech 2. Although, the codebases for ''Quake'' and ''Quake II'' were separate GPL releases. History The ''Quake'' engine was developed from 1995 for the video game ''Quake'', released on June 22, 1996.

Nexuiz
''Nexuiz'' is a free first-person shooter video game developed and published by Alientrap. The game was released under the GNU General Public License (GPL) and uses the DarkPlaces engine, a modified ''Quake'' engine. A remake, also called ''Nexuiz'', has been released for Steam and Xbox 360 using CryEngine 3. The original game was released on May 31, 2005. Gameplay ''Nexuiz'' is primarily multiplayer (though it includes a full single-player campaign, which allows one to play through the various multiplayer game types and maps with bots), and allows for hosting and joining of games. It supports new gametypes, or whole conversions quickly applied to it (much like '' Quake''). Development ''Nexuiz'' development started as a ''Quake'' modification in the summer of 2001 by Lee Vermeulen. Soon afterward the project moved to the DarkPlaces engine created by Ashley Hale, who later also joined the project. The original design called for a simple deathmatch project with a f ...

Strafe Jumping
Strafing is the act of moving sideways in a video game relative to the player's forward direction. Strafing allows a player to keep the camera focused on a target such as an enemy, while moving in a different direction. Techniques Circle strafing Circle strafing is the technique of moving around an opponent in a circle while facing them. Circle strafing allows a player to fire continuously at an opponent while evading their attacks. Circle strafing is most useful in close-quarters combat where the apparent motion of the circle strafing player is much greater than that of their stationary enemy, and thus the chance of making the enemy lose track of their target is higher and/or the enemy is required to lead the target when firing. The effectiveness of circle strafing is mitigated when the opponent's weapon fires projectiles that travel instantaneously (also referred to as a hitscan weapon), or fires at a high rate, e.g. with a machine gun. Circle strafing is especially effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bloom (shader Effect)
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of an extremely bright light overwhelming the camera or eye capturing the scene. It became widely used in video games after an article on the technique was published by the authors of ''Tron 2.0'' in 2004. Theory The physical basis of bloom is that, in the real world, lenses can never focus perfectly. Even a perfect lens will convolve the incoming image with an Airy disk (the diffraction pattern produced by passing a point light source through a circular aperture). Under normal circumstances, these imperfections are not noticeable, but an intensely bright light source will cause the imperfections to become visible. As a result, the image of the ...

Rocket Jumping
In shooter games, rocket jumping is the technique of using the knockback of an explosive weapon, most often a rocket launcher, to launch the shooter into the air. The aim of this technique is to reach heights and distances that standard character movement cannot achieve. Although the origin of rocket jumping is unclear, its usage was popularized by '' Quake''. Rocket jumping is used often in competitive play, where it can allow the player to gain quick bursts of speed, reach normally unobtainable heights, secure positional advantages, or in speedrunning. However, a potential consequence of rocket jumping is that it can injure the player, either from the blast or from fall damage. This effect makes the technique less useful in games where the damage from the blast and/or fall is high, or where health is difficult to replenish. Rocket jumping from standing is impractical in real life, and would be certainly fatal if attempted. However, ejection seats from an aircraft are, in effect, a ...

Dynamic Lighting
Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources, models, shading techniques, and effects to suit the needs of each application. Light sources Light sources allow for different ways to introduce light into graphics scenes. Point Point sources emit light from a single point in all directions, with the intensity of the light decreasing with distance. An example of a point source is a standalone light bulb. Directional A directional source (or distant source) uniformly lights a scene from one direction. Unlike a point source, the intensity of light produced by a directional source does not change with distance over the scale of the scene, as the directional source is treated as though ...

Deathmatch (gaming)
Deathmatch, also known as free-for-all, is a gameplay mode integrated into many shooter games, including first-person shooter (FPS), and real-time strategy (RTS) video games, where the goal is to kill (or "frag") the other players' characters as many times as possible. The deathmatch may end on a ''frag limit'' or a ''time limit'', and the winner is the player that accumulated the greatest number of frags. The deathmatch is an evolution of competitive multiplayer modes found in game genres such as fighting games and racing games moving into other genres. Description In a typical first-person shooter (FPS) deathmatch session, players connect individual computers together via a computer network in a peer-to-peer model or a client–server model, either locally or over the Internet. Each individual computer generates the first person view that the computer character sees in the virtual world, hence the player sees ''through the eyes'' of the computer character. Players are ...

Offset Mapping
Parallax mapping (also called offset mapping or virtual displacement mapping) is an enhancement of the bump mapping or normal mapping techniques applied to textures in 3D rendering applications such as video games. To the end user, this means that textures such as stone walls will have more apparent depth and thus greater realism with less of an influence on the performance of the simulation. Parallax mapping was introduced by Tomomichi Kaneko et al., in 2001.Kaneko, T., et al., 2001Detailed Shape Representation with Parallax Mapping In Proceedings of ICAT 2001, pp. 205-208. Parallax mapping is implemented by displacing the texture coordinates at a point on the rendered polygon by a function of the view angle in tangent space (the angle relative to the surface normal) and the value of the height map at that point. At steeper view-angles, the texture coordinates are displaced more, giving the illusion of depth due to parallax effects as the view changes. Parallax mapping descr ...

High-dynamic-range Rendering
High-dynamic-range rendering (HDRR or HDR rendering), also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios. Video games and computer-generated movies and special effects benefit from this as it creates more realistic scenes than with more simplistic lighting models. Graphics processor company Nvidia summarizes the motivation for HDR in three points: bright things can be really bright, dark things can be really dark, and details can be seen in both. History The use of high-dynamic-range imaging (HDRI) in computer graphics was introduced by Greg Ward in 1985 with his open-source Radiance rendering and ''lighting simulation'' software which created the first file format to retain a high-dynamic-range image. HDRI languished for more than a decade, held back by limited computing power, storage, and ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
