【摘要】：隨著計算機技術的飛速發(fā)展,CG(Computer Graphical)元素越來越多的在各個方面影響著人們的生活。其中包括了常見的電影特效、電視廣告、游戲、以及虛擬現(xiàn)實。虛擬現(xiàn)實技術,是多媒體技術廣泛應用后興起的計算機新技術,通常情況下可用于包括虛擬場景、虛擬產(chǎn)品、虛擬規(guī)劃、房地產(chǎn)、博物館甚至是軍事仿真領域。 諸城恐龍園VR系統(tǒng)是一個以恐龍為主要元素的主題性VR系統(tǒng),該系統(tǒng)主要描述了不同時期恐龍的形態(tài)、動作、叫聲以及恐龍的生活環(huán)境,通過利用虛擬攝像機的位移來使得用戶能夠更直接的了解有關于恐龍的知識。與此同時,本系統(tǒng)也支持用戶通過虛擬攝像機的位移旋轉等操作來進行與恐龍之間的互動。對于系統(tǒng)場景模型建模而言,本文主要利用Paint Effects筆刷庫中豐富的植物筆刷,輕松實現(xiàn)很多炫目的建模效果。對于界面設計而言,主要研究如何利用簡潔生動的過場動畫來完成對于時間軸變化的控制,從而完成對于時間、空間的過渡。針對于本系統(tǒng)特點,從系統(tǒng)的實際制作出發(fā),主要的研究工作以及成果包括以下幾個部分: 1.在詳細分析系統(tǒng)需求和核心技術的基礎上,提出系統(tǒng)整體框架設計方案。 2.通過歸納不同種類樹木的結構特點,完成系統(tǒng)基本樹木的模型框架建模,結合Paint Effects工具建模特點進行來進行模型繪制,同時利用路徑曲線完成對于模型的動態(tài)生成。 3.通過對比不同種類草地植物的結構特點,完成系統(tǒng)基本草地植物的模型建模,同時研究粒子系統(tǒng)生成,結合Sprite顯示屬性完成草地類植物模型建模。 4.通過歸納不同種類恐龍?zhí)攸c,完成系統(tǒng)恐龍模型建模,分析恐龍模型多邊形特點,完成系統(tǒng)恐龍模型的基礎模型分類和基本制作。完成多邊形建模方法結合粒子系統(tǒng)實例化來對于恐龍群體建模。結合實際恐龍園地形結構特點以及各種特殊地形地貌,完成恐龍園標準地形建模。建立恐龍基本動態(tài)庫,結合Skeleton工具來進行對于模型的動態(tài)制作其中包括奔跑、撕咬、追逐、吼叫等。 5.結合本系統(tǒng)發(fā)展方向和系統(tǒng)主題完成系統(tǒng)界面設計,依據(jù)虛擬攝像機的位移與恐龍模型的距離產(chǎn)生互動,擊發(fā)恐龍的包括奔跑、撕咬、追逐、吼叫等事件反饋。同時利用數(shù)據(jù)頭盔來進行對于系統(tǒng)的沉靜式虛擬,結合利用數(shù)據(jù)手套進行點觸式擊發(fā)事件。 6.通過對系統(tǒng)進行測試并對數(shù)據(jù)進行分析。主要對系統(tǒng)顯示真實度、交互性能、數(shù)據(jù)延遲、數(shù)據(jù)存儲效率等相關數(shù)據(jù)進行測試,測試的結果驗證了設計構想,能夠滿足項目的需求。
[Abstract]:With the rapid development of computer technology, CG (Computer Graphical) elements affect people's lives more and more. These include common movie effects, TV ads, games, and virtual reality. Virtual reality (VR) is a new computer technology developed after the wide application of multimedia technology. It can be used in the fields of virtual scene, virtual product, virtual planning, real estate, museum and even military simulation. The VR system in Zhucheng Dinosaur Garden is a thematic VR system with dinosaurs as its main element. The system describes the morphology, movements, sounds and living environment of dinosaurs in different periods. By using the displacement of virtual cameras, users can learn more directly about dinosaurs. At the same time, the system also supports users to interact with dinosaurs through virtual camera displacement rotation and other operations. For system scene modeling, this paper mainly uses the abundant plant brushes in the Paint Effects brush library to easily realize a lot of dazzling modeling effects. For interface design, the main research is how to control the time axis change by using vivid and concise animation to complete the transition of time and space. According to the characteristics of the system, the main research work and results are as follows: 1. Based on the detailed analysis of the system requirements and core technologies, the design scheme of the overall framework of the system is proposed. 2. By summarizing the structural characteristics of different species of trees, the model framework modeling of the basic trees of the system is completed, and the modeling characteristics of Paint Effects tools are combined to draw the model. At the same time, the dynamic generation of the model is accomplished by using the path curve. 3. By comparing the structural characteristics of different species of grassland plants, the model modeling of basic grassland plants in the system is completed. At the same time, the generation of particle system is studied, and the model modeling of grassland plants is completed with Sprite display attributes. 4. By summarizing the characteristics of different kinds of dinosaurs, the modeling of the system dinosaur model is completed, the polygon characteristics of the dinosaur model is analyzed, and the basic model classification and basic making of the system dinosaur model are completed. The polygon modeling method combined with particle system instantiation is used to model the dinosaur population. The standard terrain modeling of the dinosaur garden is completed by combining the topographic structure characteristics of the actual dinosaur garden and various special landforms. The basic dynamic library of dinosaurs was established, and the model was made dynamically with Skeleton tools, including running, biting, chasing, roaring and so on. 5. According to the displacement of the virtual camera and the distance between the dinosaur model and the system interface design, the system interface design is completed, and the dinosaurs' running, biting, chasing, roaring and other incident feedback are generated according to the displacement of the virtual camera and the distance of the dinosaur model. At the same time, the data helmet is used to simulate the system, and the data glove is used for the point-touch event. 6. Test the system and analyze the data. The system display reality, interactivity, data delay, data storage efficiency and other related data testing, the test results verify the design concept, can meet the needs of the project.
