Crawler cranes are the most expensive and frequently shared resource on construction sites, industries, etc. According to the characteristics of crawler crane, this paper presents a multiple modeling method of crawler crane based on OGRE (Object-oriented Graphics Rendering Engine) and Bullet Dynamic Engine. The multiple model is composed of rendering model, collision model, skeleton model and dynamic model. Based on this modeling method, not only vivid figuration and motion of the crane but also real-time collision detection and distance computation can be achieved.

According to the crawler crane’s structure and the scene management principle of OGRE (Object-Oriented Graphics Rendering Engine), this paper presents a new 3D parameterized modeling method of crawler cranes. By integrating the interactive modeling using 3DSMAX and the geometrical graphics modeling, the new method can solve the problem about rendering speed, vivid and parameterized models and how to obtain the position of key points. A case is described in order to demonstrate the use of the developed method and to illustrate its reliability.

Modeling System for Construction task Simulation (MSCS) presented in this paper is a 3D computer-aided drawing tool which is designed for construction task planners. It is based on OGRE (Object-oriented Graphics Rendering Engine) and Bullet Dynamic Engine, therefore the model created by MSCS has both geometric and dynamic properties. MSCS has already been used in Crawler Crane’s Lifting Simulation System which is developed by Dalian University of Technology in China to draw the work environment and the loads to be lifted.

The animation construction of forest scene is a virtual stand scene visualization framework which uses the related technologies of virtual forest modeling and stand scene visualization, and uses the scene graph technology to manage. This paper studies the influence of digital media technology on the animation design of forest scene. In this paper, the model of virtual stand scene is mainly completed by Creator modeling software of MultiGen company. In order to reduce the number of scene patches and ensure realism, the tree model is designed with OpenFlight tree hierarchy. At the same time, the key technologies of Creator modeling and model optimization are analyzed. The virtual stand scene visualization framework uses the open source graphics rendering engine OpenSceneGraph (OSG) as the scene driver to realize the stand scene visualization. This paper provides a variety of roaming control methods. The experimental results show that the virtual forest scene visualization framework can better simulate the forest scene and has a strong sense of reality.

Early information systems were mainly built around secondary, administrative processes of the value chain (e.g., accounting). But since the internet came into use, more and more primary processes have become accessible to automation: customer acquisition, ordering, billing and, in the case of intangible goods such as software, even delivery. Hence an increasing part of an enterprise has to be modeled and a substantial part thereof is implemented, usually in an object-oriented programming language like Java. To facilitate this complex task, the MEMO methodology (Multi-perspective Enterprise MOdeling) allows the description of the enterprise on three levels – strategy, organization and information system – and from four angles – process, structure, resources and goals. All partial models for the views are integrated via a common object-oriented core. In this framework we suggest a modeling method for the IS layer, the Event-driven Method Chain (EMC). It is based on the Event-driven Process Chain (EPC) by Scheer, which we adapt to fit both the MEMO methodology and the object-oriented paradigm thus making it suitable for the development of web-based applications. To illustrate this we use the example of a software trading company.

This article puts forward object-oriented Petri net modeling method, which possesses good encapsulation and modularity compared with current ordinary modeling method. On the macro level, it divides the re-entrant lines into different object modules according to the technology, so that the complexity of models is largely reduced through message delivery between objects. In the micro level, it explains objects' internal operational mechanism, in another word, each object's internal operation cannot be affected by other objects and environment. At last, it makes modeling and dynamic analysis by taking LED chips' processing flow for example, showing that re-entrant lines model based on object-oriented Petri net possesses good modeling ability.
