摘要：本课题是基于Unity3D技术之上的关于农林行业方面的应用功能的实现，研究的目的在于模拟仿真出林间漫游和作业的流程，以实现林间可视化的一小部分。本课题在功能上实现了3个部分，分别为：其一，在一块模拟林间生态环境的三维地形中进行第一人称视角的漫游；其二，在漫游的场景地形一块较为空旷的地区，对已有标识的树木进行油锯伐木作业的操作体验，过程中存在操作提示，按照提示进行操作即可；其三，在一个以厂房为背景的场景中进行油锯的拆装交互，其中包括拆装的演示和手动操作的拆装。本课题研究的特色在于，用户可以足不出户地在电脑上较好地体验在林间环境内的漫游和某些林间作业的交互操作，进而熟悉某林区其中一片的生态环境及整个作业的大概流程和知识，而不必特意去某些林区进行实地考察。79742

Function Realization Based on Unity3D of Forest Roaming and the Application of Chain Saw

Abstract: This project is a realization of the application function in agriculture and forestry industries, based on the technology of Unity3D。 The purpose of the study is to simulate the process of roaming and operations in the forest, to realize a small part of forest visualization。 In this paper, three parts are realized in function: Firstly, users in the first person perspective can roam in a three-dimensional terrain of the forest that ecological environment is simulated; Secondly, in the relatively open area of the roaming scene, there is an operational procedure for the operation of the saws’ cutting, and there are also some tips in the process, which users can go on smoothly according to; Thirdly, in a scene with the background of a factory, users can interact with the disassembly and assembly of the chainsaw, including demonstration and manual operation for disassembly and assembly。 The feature of this research is that users can experience, on the computer indoor, the roaming in the forest environment and the interaction of certain forest operations, to be familiar with the ecological environment in an area of the forest and the approximate process and knowledge of the whole operation, without specifically going to some forest areas for on-the-spot investigation。
