“…Apart from VFC, another popular culling technique is occlusion culling, which tries to determine objects that cannot be seen from the camera due to groups of other objects that lie between them and the camera [318] [187]. Occlusion culling depends on how the ob-jects affect (occlude) each other.…”

However, Nico Hempe's work, documented in this thesis achieves nothing less than a functional and proven software structure to cope with the request for realism in the ever increasing complexity of today's robotic and mechatronic applications. Over the decades, modeling for computer simulation and visualization has progressed from an early reliance on purely geometric models to extremely powerful simulation models which also incorporate the underlying physical principles. Nico's is to date one of the most important PhD dissertations which manage to bridge the gap between advanced simulation and comprehensive rendering techniques by combining the best of both worlds to impressive virtual reality applications. His virtual worlds, which do not only look good but serve as the basis for virtual testbeds, are key components in new development approaches in the context of eRobotics and "Industry 4.0". Starting in 2010, Nico's work helped to establish the research field of eRobotics in order to cope with the inherent complexity, facilitate the development and significantly cut down the cost of advanced robotics and mechatronics applications. The objective is to effectively use electronic media -hence the "e" at the beginning of the term -to achieve the best possible advancements in the development of the robots' respective fields of use. Current domains of eRobotics covered by Nico's work comprise industrial robotics, work machines, construction site automation, space robotics and even the fields of environmental and city modelling. This thesis reveals the technical details behind a spectacular accomplishment in com...

Hardware occlusion queries is a method by which graphic processing unit (GPU) can gives fast response to the visibility status of a geometry object in virtual environment. Increasing number of issued queries lead to stall in CPU and starvation in GPU. However, hardware occlusion queries have improved by exploiting temporal coherence (TC). TC is proven improved hardware occlusion queries based on previous research. In driving simulation as car or camera move fast, more and more objects in scene become less significant to be rendered. Implementation of TC on driving simulation need be redesigned so allow TC suitable to faster movement. Intent of this paper is to describe how automatic parameters adaptation in temporal coherence is applied to driving simulation environment. Automatic parameters adaptation manipulated when the car or camera movement become more faster to maintain interactively rendering process and maintain realisms of complex virtual environment.

The generation of real-time 3D graphics scenes normally demands high computational requirements. Several applications can benefit from efficient algorithms for rendering complex virtual environments, such as computer games, terrain visualization, virtual reality and visual simulation. This paper describes an improved view frustum culling method using spatial partitioning based on octrees for 3D real-time rendering. The proposed method is compared against two other approaches. Experiments using four different scenes are conducted to evaluate the performance of each tested method. Results demonstrate that the proposed method presents superior frame rate for all scenes.
