Abstract. Night raid became more and more important in modern conflict
because of the wide use of different kinds of night vision equipments; this is why
the night training is playing an important role in military training. As an impor-
tant method of military training, simulated training could not lose sight of night
training. In this essay, we will consider the followings: firstly, the light properties
of real time 3D graphics engine in OpenGVS4.5; secondly, the simulation of the
vision effect of night environment, low-light-level night vision, and infrared
night-vision scope; and finally, the results of our research that have been applied
in a variety of driver training simulators and the satisfaying effect of the training.

Keywords: Night vision simulation, low-light-level night vision simulation and
infrared thermal image simulation.

1 Introduction

In recent years, the 3D graphic and simulation technology had been continually
improved since different kinds of training simulator became more and more acceptable.
With the improved fidelity of simulators, the 3D graphic and simulation technology
became an efficient and important training method that has the characteristic of safety,
environmental friendly, all-weather suitable and low cost. Driving training simulator
offered a wide range of subject according to the requirements of driving: the whole
process of driving is simulated, and all necessary skills for driving are focused on. The
Driving simulation training had been an important auxiliary method of driving training,
especially for tank driving training.
Night fighting is common in modern war, and is becoming more and more impor-
tant. Night training is becoming an important training part in order to better prepare our
army for the war in the future. In tank driving training, more than one-third is driving
training at night. Therefore, night training simulation would directly affect the overall
performance of the driving simulation.

OpenGVS was one of the Quantum3D company's products which developed a real-time
visual simulation scene graph. OpenGVS provided a variety of visual simulation functions
