Rendering for a Better
Augmented Reality
Miguel Churruca, Marketing and Communications Director,
Brainstorm, considers the increasing demand for realism...

V

iewers are more demanding on
the realism of virtual content,
and this is especially critical on
Augmented or Mixed Reality broadcast
projects. Addressing this not only
requires high-quality rendering, but
also perfect integration between
the different elements of the scene
to provide a sense of realism, with
precise perspective matching and
correct broadcast continuity.
To achieve this, real-time graphics
render engines developed for
broadcast sometimes need to co-exist
with gaming or architectural render
engines, which can provide excellent

Demands for more realistic virtual content

rendering results for backgrounds and
scenes, allowing for realistic results
on these renderings. But Augmented
Reality broadcast applications also
require the interaction between sets,
talents and virtual objects, many of
them created out of external data
sources such as statistics, charts or
bars, which are perfectly rendered by
real-time broadcast graphics render
engines such as Brainstorm's.
Along with advanced imaging and
rendering features such as HDR (High
Dynamic range) and PBR (Physically
Based Rendering), Brainstorm also
supports gaming and architectural
engines like Unreal Engine. These
highly complex engines provide
realistic scenes, and played along with
Brainstorm's eStudio render engine
allows InfinitySet not only to show
excellently rendered background
scenes, but also to integrate datadriven graphics elements in the final

scene, like 3D motion graphics, lowerthirds, tickers, CG and many other
elements.
Brainstorm's approach to external
render engine support is unique in
the industry, as it features such deep
integration that allows InfinitySet
to control different Unreal Engine's
parameters in real-time, as opposed
to other solutions which rely on
different machines to render the
different scenes and graphics to later
combine them. Most importantly,
Brainstorm's approach for merging
both engines' render parameters and
buffers, makes them work as a single
render engine, and working in a single
machine (Combined Render Engine
- as Fig.1). This simplifies setups as it
does not require additional hardware
such as studio mixers.
InfinitySet can control, from its
own GUI, different parameters of
Unreal Engine's Scenegraph (World

Fig.1: Combined

Render Engine

Outliner), including cameras, via the
parameter's ID. InfinitySet does this
by converting Unreal Engine's World
Outliner list into a Brainstorm list and
exposing the equivalent parameters
in the InfinitySet interface. Unreal
Engine's
render
buffers
are
transferred to the InfinitySet engine
in real-time, allowing the combined
engine to add the chromakeyed talent,
the data-driven graphics and other
elements.
InfinitySet's TrackFree™ technology
allows for tracked, fixed cameras or
any combination of them to shoot
the talent on the set using internal
or external chromakeyers, and when
using fixed cameras, InfinitySet can
move the scene rendered by Unreal,
by using the internal mixer's camera
presets.
