Neothyne

Neothyne is an attempt at getting back to the roots of good old twitch shooting akin to that of Quake World.

Here's what it looks like currently

Philosphy

A modern dependency free game engine to make a twitch shooter with

Status

As of late Neothyne is just an engine offering

• Efficent KD-tree (which allows for)

  • Efficent static and sweeping collision detection
  • Efficent scene management
  • Smooth world traces for accurate and efficent collision response

• Deferred renderer (which can do)

  • Directional lighting (with ambient and diffuse terms)
  • Specular lighting (with power and intensity terms)
  • Point lighting (with omnidirectional shadow mapping)
  • Spot lighting (with shadow mapping)
  • Skybox
  • Soft particles
  • Normal mapping (dot3 bump mapping)
  • Displacement mapping (steep parallax and relief mapping)
  • Fog (linear, exp and exp2)
  • Fast approximate anti-aliasing (FXAA)
  • Screen space ambient occlusion (SSAO)
  • Vignette
  • View frustum culling
  • Skeletal model animation (IQM)
  • Variable color grading (supporting)
    • Color balance (shadows, midtones and highlights)
    • Hue, lightness and saturation
    • Brightness and contrast

• Scripting language (Neo language)

  • Heavily inspired by Javascript, C++, Lua, Ruby, C#, Java (In order of inspiration)
  • Dynamically typed (with optional typing)
  • Structured
  • First class values
  • Lexically scoped
  • Type rich (function, method, bool, int, float, string, array, object)
  • Object oriented (Single inheritence multiple-interface)
  • Garbage collected

• Fire and forget audio mixer (which can do)

  • Multiple sound sources (global and local)
  • Faders (adjust volume, speed, panning over time)
  • Dynamic audio control
    • Fade volume, speed, panning, etc.
    • Panning
    • Speed
    • Filters
      • Echo
      • Biquadratic Resonance Filters
        • Low pass
        • Hi pass
        • Band pass
      • DC Blocking
    • Audio grouping

• Immediate-mode graphical user interface (which can do)

  • Buttons
  • Items
  • Check boxes
  • Radio buttons
  • Windows
  • Collapsible areas
  • Labels (left-justified text)
  • Values (right-justified text)
  • Sliders (horizontal and vertical)
  • Indentation
  • Headers (vertical separations and lines)
  • A variety of raw rendering primitives (such as)
    • Lines
    • Rectangles
    • Text
    • Images
    • Models

• Console (which allows for)

  • Global configuration
  • History and tab completion
  • Reactive changes to various engine components (including renderer)

• Asset optimization (which can do)

  • Online texture compression
  • Online linear-speed vertex cache optimization
  • Online half-precision float conversion
  • DXT end-point optimization (helps old hardware DXT decode fetches)

Goals

• Networking (client/server model)
• Build the game
• Scripting

Etymology

• Neo (Old English from Proto-Germanic: nawiz, nawaz, i.e: "corpse")
• Thyne (Old English: thyn, þyn. Cognate to German: dein, i.e: "yours")

In modern English: "your corpse"

System requirements

Neothyne requires a GPU which is capable of GL 3.0. Modern low profile GPUs may function poorly. (Note: Some cards are advertised as being GL 2 capable, but with newer drivers, can become GL 3 capable. This is the case for some cards in the GeForce 8 series, for example.)
