【摘要】：近年來(lái),BIM的快速發(fā)展給土木工程建設(shè)帶來(lái)了革命性的影響,工程項(xiàng)目的設(shè)計(jì)與施工也由傳統(tǒng)的二維逐漸過(guò)渡到三維。同進(jìn),BIM的數(shù)據(jù)共享的思想使得工程建設(shè)參與各方能夠更好地交流、溝通與協(xié)調(diào)。顯著提高了工程項(xiàng)目建設(shè)的效率,減少了在設(shè)計(jì)與施工過(guò)程中出現(xiàn)錯(cuò)誤的概率,給項(xiàng)目建設(shè)方帶來(lái)了巨大的經(jīng)濟(jì)效益。 在本文中,我們將對(duì)如何使用BIM數(shù)據(jù)庫(kù)提供的來(lái)自于不同的專業(yè)、不同的設(shè)計(jì)部門(mén)的三維管線模型的綜合性的碰撞檢測(cè)作深入的研究與探討。并通過(guò)結(jié)合MFC應(yīng)用程序框架、OSG三維渲染引擎與Bullet Physics物理引擎的功能來(lái)實(shí)現(xiàn)三維管線間的碰撞檢測(cè)功能。 本文首先介紹虛擬現(xiàn)實(shí)技術(shù)的背景與將碰撞檢測(cè)功能應(yīng)用于BIM的現(xiàn)實(shí)意義,以及物理處理引擎的發(fā)展現(xiàn)狀。接著對(duì)BIM的概念以及三維管線的設(shè)計(jì)作簡(jiǎn)單的概述。然后,我們將針對(duì)于三維場(chǎng)景的渲染與管理以及碰撞檢測(cè)的算法以及物理引擎作深入的探討。三維場(chǎng)景的渲染與管理的章節(jié)主要探討了三維圖形渲染管線的基本知識(shí)與著色器的基本概念與用法,以及OSG圖形渲染引擎的基本的圖形渲染與場(chǎng)景管理知識(shí)。碰撞檢測(cè)的章節(jié)主要探討了兩階段劃分理論與在各階段適用的算法分類,碰撞檢測(cè)算法的基礎(chǔ)包括包圍體概念、圖元測(cè)試、包圍體層次、空間劃分與BSP樹(shù)、凸體測(cè)試等,以及Bullet引擎的相關(guān)知識(shí)。 最后,本文通過(guò)結(jié)合OSG引擎與Bullet Physics引擎設(shè)計(jì)出一個(gè)具有基本的三維圖形渲染與場(chǎng)景管理功能與碰撞檢測(cè)功能的應(yīng)用系統(tǒng)。系統(tǒng)著重講述了場(chǎng)景數(shù)據(jù)的讀寫(xiě)與管理、場(chǎng)景的組織與渲染、場(chǎng)景與用戶的交互實(shí)現(xiàn)、碰撞檢測(cè)的實(shí)現(xiàn)與結(jié)果的組織等內(nèi)容。本系統(tǒng)在個(gè)人計(jì)算機(jī)上具有很好的穩(wěn)定性,在處理大量的三維管線數(shù)據(jù)模型的渲染與碰撞檢測(cè)時(shí)具有較快的速度與較高的效率。
[Abstract]:In recent years, the rapid development of BIM has brought a revolutionary impact on civil engineering construction, and the design and construction of engineering projects have been gradually transferred from traditional two-dimensional to three-dimensional. The idea of data sharing with BIM enables all parties involved in engineering construction to communicate, communicate and coordinate better. The efficiency of project construction is improved significantly, the probability of error in design and construction is reduced, and great economic benefit is brought to the project constructor. In this paper, we will make an in-depth study and discussion on how to use the BIM database to provide comprehensive collision detection of 3D pipeline models from different professional and different design departments. The collision detection function between 3D pipeline and 3D pipeline is realized by combining the functions of MFC application framework, MFC 3D rendering engine and Bullet Physics physical engine. This paper first introduces the background of virtual reality technology, the practical significance of applying collision detection to BIM, and the development of physical processing engine. Then the concept of BIM and the design of three-dimensional pipeline are briefly summarized. Then, we will discuss the rendering and management of 3D scene, collision detection algorithm and physical engine. The chapter on rendering and management of 3D scene mainly discusses the basic knowledge of 3D graphics rendering pipeline, the basic concept and usage of shader, and the basic knowledge of graphics rendering and scene management of OSG graphics rendering engine. The chapter of collision detection mainly discusses the theory of two-stage partition and the classification of algorithms applied in each stage. The basis of collision detection algorithm includes bounding volume concept, graph element testing, bounding volume level, space partition and BSP tree, convex body testing, etc. And knowledge of Bullet engine. Finally, by combining OSG engine with Bullet Physics engine, this paper designs an application system with basic functions of 3D graphics rendering, scene management and collision detection. The system focuses on the reading, writing and management of scene data, the organization and rendering of scene, the interactive realization of scene and user, the realization of collision detection and the organization of result. The system has good stability on personal computer, and has high speed and high efficiency in dealing with a large number of 3D pipeline data model rendering and collision detection.
