1 INTRODUCTION
The report of the 19th National Congress of the
Communist Party of China clearly pointed out that
the implementation of Rural Revitalization Strategy,
and gradually realize the sustainable development of
ecological civilization (Liu, Liu, Jing, et al. 2012). At
the same time, "opinions on Rural Revitalization
Strategy" and "Rural Revitalization strategic
planning (2018-2020)" also put forward that Rural
Revitalization Strategy should be implemented, and
rural environmental governance is the only way to
implement Rural Revitalization Strategy (Ren 2021),
and good environment is an important foundation
and guarantee for the development of rural economy
(Du 2021). The comprehensive governance of rural
ecological environment is the only way to realize the
green agricultural production and low-carbon
agricultural life, and then realize the transformation
of rural economic development (Gao 2018). The
environmental governance of hometown village is an
important national development strategy, and
accompanied by the application of network,
informatization and digitization in the development
of rural economy and society, Digital governance of
rural environment has become the focus of current
research (M A, Zhang, Liu 2019).
Therefore, this paper first introduces the latest
digital technology of 3D scene representation,
namely cesium for unreal, which combines the 3D
geospatial function of cesium with the high fidelity
rendering ability of virtual engine 4 (UE4). The
combination of cesium technology and virtual engine
4 technology realizes the creation of 3D environment
from real to digital. Then, the digital and visual
construction of rural environment is realized by using
cesium for unreal technology. The construction
results of this paper will help policy makers
intuitively and comprehensively understand the
situation of rural environmental governance, quickly
grasp the overall situation of the target area, and be
conducive to the digital governance of rural
environment.

UE4 is a popular game development engine all over
the world (Tian 2021). The Unreal engine is a
complete set of integrated tools for building games,
simulation and visualization, with sufficient
flexibility to meet the needs of development teams of
different sizes (Wang 2021). Unreal engine is the
most open and advanced real-time 3D creation
platform in the world. After continuous improvement,
it is not only a temple-level game engine, but also
brings unlimited creative freedom and
unprecedented control to professionals in various
industries. Whether it's cutting-edge content,
interactive experiences, or immersive virtual worlds,
it's all in the illusory engine.
The Unreal engine is a palace-level real-time
engine and editor, with photo-level realistic
rendering functions, dynamic physics and effects,
lifelike animation, robust data conversion interface
and so on. It is an open and extensible platform that
can bring you unlimited creative freedom.
With the unprecedented demand for real-time 3D
technology in digital countryside, learning illusory
engine has become the best way to expand digital
countryside.
2.3 Cesium for Unreal
Cesium for Unrea, which was officially released in
2021-03-30, is a 3D Earth plug-in tailored by Cesium
for the illusory engine, which makes the unreal
engine have the ability of Google Earth and opens a
new door for simulating the real world. Cesium for
Unreal, based on open standards and API, combines
the 3D geospatial capabilities of Cesium with the
high-fidelity rendering capabilities of Unreal engines
to open the 3D geospatial ecosystem for game
engines. Cesium for Unreal enables you to create a
digital world from real-world 3D content, and use
Cesium for Unreal to create a digital world with real-
world scale and 3D content.
3 RESEARCH ON DIGITAL
CONSTRUCTION OF RURAL
ENVIRONMENT BASED ON
CESIUM FOR UNREAL
Based on cesium for unreal, the research of rural
environment digital construction is realized by
designing a three-dimensional visualization system
(Wang, Li, Zhang, Chen, Yang, Yu 2021). The
design idea of the system, first of all, the rural
environment big scene data collection and important
facilities refinement model, and then data format
conversion, using the cesium for unreal import data,
combined with blueprint interactive function and
front-end display function, realize the digital display
of rural environment (Wang, Li, Fan 2020). Finally,
through the collected sensor data and scene digital
information, based on the principle of Bryson
collaborative governance model, the environmental
governance function is developed, the factors of the
effectiveness of the target rural environmental
governance are extracted, and the governance
strategies are formulated through human-computer
interaction to provide the basis for environmental
governance.

3.2 Establishment of Fine Model of
Important Facilities
Digital governance of rural environment is
inseparable from fine model. Based on 3DMAX
software, this paper carries out fine modeling of
important facilities in the area where sensors have
been installed. The content of fine modeling mainly
includes weather station, ecological breeding plant,
public toilet, garbage can, camera, etc., so as to
realize the fine modeling in the system by clicking on
the model (Fig. 3), The real-time monitoring data and
images of the facilities can be displayed intuitively.

conversion.
3.4 Using Cesium for Unreal to Import
Cesium for Unreal is a free plug-in on Unreal engine
Mall that installs and activates plug-ins. Use the
Cesium for Unreal plug-in to import the converted
oblique photography model and fine model into UE4.
3.5 Blueprint Interaction
Blueprints are a special class of asset that can be used
to create logic in an intuitive, node-based way, or to
set up some variable data. Planners can create custom
Actor, Event, functions, etc., and do Gameplay
iterations quickly without writing any code.
The blueprint can also choose to inherit the C++
class, get the variables defined in C++, call the
functions defined in C++, or implement the event
defined in C++. The interaction between scenes is
realized by using the blueprint function.
3.6 Use Pixel Streaming to Interact
with the Front-End Page
The implementation of pixel streaming is to put the
computing that can only run on the terminal in the
cloud, and call powerful high-end computing
resources (CPU/GPU/ memory, etc.) in the cloud to

calculate. The end user uses a standard web browser
to connect to the application, of course, it can also
send a variety of control signals (mouse, keyboard,
touch, etc.) to the cloud computing node, and push
the calculated picture back to the terminal after
processing (Zhang, Zhou, Shen, et al. 2019). Pixel
streaming plug-in is integrated in UE4, and the
interaction between front-end Web interface and 3D
scene can be realized by using this plug-in. The effect
is shown in figure 5.

3.7 Realization of Environmental
Governance Function
Through the collected sensor data and scene digital
information, based on the principle of Bryson
collaborative governance model, the environmental
governance function is developed, the factors of the
effectiveness of the target rural environmental
governance are extracted, and the governance
strategies are formulated through human-computer
interaction to provide the basis for environmental
governance (Zhou, LI, Wang, et al. 2018).
4 SUMMARY
This paper first studies cesium for unreal, and finds
that this technology combines the 3D geospatial
function of cesium with the high fidelity rendering
ability of virtual engine 4 (UE4). The combination of
cesium technology and virtual engine 4 technology
can realize the creation of 3D environment from real
to digital. Furthermore, based on the research of
digital construction of rural environment of cesium
for unreal, the digital and visual construction of rural
environment is realized, which provides a scientific
basis for environmental governance. If we want to
achieve more accurate environmental governance
function, we need to further improve the
environmental model.
