“…Therefore, various element techniques such as game engine techniques with texture mapping instead of geometry, the culling technique to render only the objects contained inside the viewing frustum, and the Level of Detail (LOD) technique to change the 3D models and textures of different detail levels which depend on the distance from the VR virtual camera, have been developed to reduce the rendering load [3][4][5]. Previous studies on constructing a VR application by applying such techniques in architecture and urban fields have been reported, covering areas such as the future simulation of architecture and urban spaces at the design stage [6,7], digital archiving of existing architecture and townscapes [8], digital reconstruction of past architecture and ancient cities [9][10][11], and architectural education [12]. However, studies to construct a finely detailed realistic VR application applying these techniques using recent advances in the PC environment have not been reported.…”

Abstract. This study shows fundamental data for constructing a high-definition VR application under the theme of a three-dimensional visualization to restore past architecture and cities. It is difficult for widespread architectural and urban objects to be rendered in real-time. Thus, in this study, techniques for improving the level of detail (LOD) and representation of natural objects were studied. A digital reconstruction project of Azuchi Castle and old castle town was targeted as a case study. Finally, a VR application with specifications of seven million polygons, texture of 1.87 billion pixels, and 1920 × 1080 screen resolution, was successfully developed that could run on a PC. For the developed VR applications, both qualitative evaluation by experts and quantitative evaluation by end users was performed.

“…In order to propose an explicit representation of this regulation, some authors designed methods to generate buildable hulls from geometric constraints [3][4][5]. These hulls can be used for participation purposes or to help the design of buildings [6]. Some authors go further in the treatment of these rules by generating buildings [7][8][9] or proposing extensions to existing buildings [10].…”

Abstract:The Right to Build is defined by textual elements that determine what an owner can build on a parcel. Such regulations contain elements that can influence the development of territories. Expressed through legal texts, their effects on the territory are difficult to assess because of the documents' complexity and of the diversity of urban configurations. In this paper, we present a generic and extendable model to represent such regulations. This model is based on (1) a representation of geographical concepts (attributes, features and relations) mentioned in regulations and (2) rules formalized with Object Constraints Language (OCL). We also propose an implementation that allows the handling of formalized rules in order to check if a building configuration proposal respects urban regulations. Many applications are possible in order to assist in the conception of such regulations, land acquisition strategy or territorial evolution studies, in this article, we notably describe a future application dedicated to assist building permit surveyors.

Abstract:An increasing amount of attention worldwide has been diverted into using Building Information Modeling (BIM) tools and simulations via BIM models in the field of architecture. BIM modeling and the effective use of various types of numerical and quantitative simulation and analysis are used throughout architectural processes. Stakeholders of various parties can be better informed about projects and may offer their feedback in a more effective and rapid manner to foster better, but also speedy, decision-making, hence this type of technology is so important. In this paper, various types of software and solutions based on Information Modeling (IM) and Virtual Reality (VR) are utilized in the design of a company dormitory. Simulations via a BIM model are performed and a cloud-based 3D Virtual Reality is used for consensus building. This paper examines the detailed process of the project, the effectiveness of feedback on the design, and the process of reaching consensus. In addition to what has already been done or what is currently available, this paper also presents a summary of what will be offered in the future in terms of BIM modeling, environment simulation, and VR simulation, collectively.
