YEBIS Optic Based Post-Processing


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.

YEBIS supports three types of HDR rendering architecture

YEBIS interfaces with the HDR rendering pipeline. If the graphics engine into which YEBIS has been installed supports HDR rendering, post-effects making maximum use of its capabilities can be added. Issues regarding the mechanism and use of HDR rendering are explained in a separate section (URL). Please refer to this for more about HDR rendering itself.

YEBIS supports three general HDR rendering pipelines.

Real HDR rendering

YEBIS can operate in this mode when paired with a graphics engine rendering with RGB in 16-bit floating point format (FP16).

In other words, the graphics input into YEBIS has the HDR information in FP16 format and YEBIS then provides the high quality post-effects with as little compromise as possible.

Of the three possible modes, this one offers the highest level of operation, and it is therefore recommended for PC and arcade games played on high-spec hardware. It is expected that new hardware referred to as “next generation consoles” are also expected to use this mode.

Simulated HDR rendering

YEBIS can operate in this mode when paired with a graphics engine rendering with RGB in 8-bit integer LDR (Low Dynamic Range) format.

In LDR format, HDR information cannot be recorded as is, and the graphics engine therefore compresses the luminance range based on the given guidelines before using the HDR information. The compression method for the HDR information is provided by YEBIS, and the graphics engine follows those guidelines and compresses the luminance range non-linearly, and performs HDR rendering in the LDR format buffer.

Since the HDR information is handled extremely accurately, YEBIS delivers very high-quality post-effects in this mode.

This is a good match for next-generation consoles such as PlayStation®4 and Xbox One where Real HDR rendering is a little too load-heavy.

Pseudo-HDR rendering


Pseudo-HDR rendering

This mode is also used when paired with a graphics engine rendering with RGB in 8-bit integer LDR format.

In this mode, YEBIS creates an image from an LDR frame based on an original algorithm, with no input HDR information, and acts as if HDR rendering is performed on the spot.

This mode is effective when paired with graphics engines designed with absolutely no awareness of HDR rendering. As a result, it is useful for converting graphics rendered with older LDR graphics into HDR-like graphics with a minimum amount of work.
