YEBIS Optic Based Post-Processing


Key new features of YEBIS

YEBIS development is working to improve HDR compatibility with a number of support functions for HDR TV output. Functions such as various gamma transfer functions (OETF) including PQ, HLG, and more; and a wide range of color gamuts, such as AdobeRGB, BT.2020, DCI-P3.

Variegated Customizable Glare Effects
YEBIS has a large number of Glare effects, the most widely known being the HDR effect. Furthermore, each effect can be freely customized.  Learn More
Depth of Field Effects
Optically convincing Bokeh effects nearly indistinguishable from images photographed by actual lenses.   Learn More
Motion Blur
Create a sense of speed in the movement of a character or in the motion of a scene.  Learn More
Physically Accurate Optical Post-effects
A variety of optical effects are available, ranging from highly realistic to more dramatic.  Learn More
Three Selectable HDR Rendering Effects
All of the post-effects in YEBIS interface with the HDR rendering pipeline. Three types of HDR rendering pipelines are supported, and can be selected based on performance of the target platform and design of the graphics engine.
  Learn More
Post-process Anti-aliasing
YEBIS offers a new, low load anti-aliasing technique for handling jagged edges that can’t be fully removed with the general MSAA method.  Learn More
Artistic and special effects
YEBIS excels in delivering photo-realistic effects and is also capable of creating more expressionistic and avant garde-style effects that evoke emotions.
  Learn More
Easy to Install Architecture Also Supports DirectX11 Generation Tech
No major revisions to the graphics engine are required when installing YEBIS. It is connected directly.  Learn More
Color Adjust
The monotone, sepia tone, and saturation (etc.) of rendering effects can be changed in real-time.  Learn More
A Proprietary Processing Algorithm Balancing Quality and Performance
Scaleable design ensures that even if speed is a priority, high quality performance can be achieved, and even if high quality is a priority, speed can be achieved.  Learn More

YEBIS - Reality Acceleration Post-effect Middleware Enters its 2nd Generation

YEBIS a post-effects middleware solution
Even in an age of advanced programmable shaders, it is still difficult to simulate and implement all graphical effects natively within a game. Silicon Studios’ graphic developers have therefore created post-effect technology for effective and convincing real-time visuals across numerous platforms.
Briefly explained, post-effects are visual effects added during post-processing to a frame that has already been fully rendered in order to enrich its visuals. Although not unlike the process of retouching photos taken with a digital camera, post-effects used in real-time graphics employ a special algorithm for retouching, and generating effects in real-time.
YEBIS is middleware that enables such post-effects.

YEBIS is unique because of its method of processing algorithms in a way that are as physically and optically correct as possible. Visuals are therefore much more realistic and convincing than those obtained with general post-effects processing. YEBIS comes with a multitude of post-effects supporting a variety of purposes and applications. In addition to being able to use post-effects as provided, they can also be used to create original post-effects by customizing the parameters. YEBIS is a middleware system offering post-effects, so the visuals targeted for processing are first created by the client’s graphics engine. In other words, YEBIS runs as an attachment to the client’s graphics engine. The process of integrating YEBIS to your existing graphics engine is dramatically simple, and requires virtually no changes to your engine. In other words, effects can be added to already finished graphics without being influenced by the complexity of the existing graphical scene.
Architecture suitable for game graphics development   Click to Read More
Although YEBIS is suitable for all types of real-time graphics development, it is particularly powerful for development of graphics for video games.
With game graphics that place a high priority on real-time processing, it is necessary to achieve high performance while also maintaining convincingly realistic quality. In order to achieve a high level of technical expertise and many years of experience are required.
The development of YEBIS revolved around Masaki Kawase, the man who led the movement toward programmable shaders, and the creator of many commonly used techniques which permeate the entire game development scene through his ‘Kawase Method’. Perhaps for that reason, YEBIS has successfully constructed unmatchable algorithms that, in comparison with other general post-effects systems, allow for higher quality graphics despite the focus on speed, and higher performance despite the focus on quality.
This characteristic makes it possible to work just as effectively on mobile devices as it does on high-end consoles. It is also the reason that this tool is superior for development of game graphics across multiple platforms with wide variations in expressiveness and functionality.
The direct descendent of YEBIS, inheriting all its features, has arrived and is targeted not only at existing platforms, but also at the next generation of consoles.
Its name is YEBIS.
