This research investigated the impact of synchronous distributed non immersive cloud-VR (cloud computing type of Virtual Reality) meetings using the annotation function by noting an architectural design process. The experimentation of collaborative design work at the early stage of a housing renovation project was executed by three designers. The synchronously distributed meetings using cloud-VR and a freehand sketching function were completed in two days. The annotation function was used effectively when a designer wished to show the space composition and volume shape of the planned building and so on. The proposed design environment, sharing a 3D virtual space with viewpoints, plans, sketches and other information synchronously and remotely, was feasible and effective.

This document describes the development of a high-definition virtual reality application reconstructing Azuchi Castle and its old town in 1581. Researchers created 3D models with over 7 million polygons and texture maps with over 1.8 billion pixels. Level of detail techniques and procedural modeling were used to render the large-scale environment in real-time. Qualitative feedback from VR experts noted realistic details but inconsistencies in shading and shadows. A survey of 286 end-users found 88% rated the VR experience as good or very good and 89% found it very or interesting. The project aims to use this VR system for tourism, education and civic pride in the local area.

This slide is presented in CDVE2012 (The 9th International Conference on Cooperative Design, Visualization, and Engineering).
Abstract. This research presents the availability of a landscape simulation method for a mobile AR (Augmented Reality), comparing it with photo montage and VR (Virtual Reality) which are the main existing methods. After a pilot experiment with 28 subjects in Kobe city, a questionnaire about three landscape simulation methods was implemented. In the results of the questionnaire, the mobile AR method was well evaluated for reproducibility of a landscape, operability, and cost. An evaluation rated as better than equivalent was obtained in comparison with the existing methods. The suitability of mobile augmented reality for landscape simulation was found to be high.

This slide is presented in CAADRIA2012 (The 17th International Conference on Computer Aided Architectural Design Research in Asia).
Abstract. The mobility of people's activities, and cloud computing technologies are becoming advanced in the modern age of information and globalisation. This study describes the availability of discussing spatial design while sharing a 3-dimensional virtual space with stakeholders in a distributed and synchronised environment. First of all, a townscape design support system based on a cloud computing type VR system is constructed. Next, an experiment of a distributed and synchronised discussion of townscape design is executed with subjects who are specialists in the townscape design field. After the experiment, both qualitative mental evaluation and quantitative evaluation were carried out. The conclusions are as follows: 1. Users who use VR frequently and who use videoconferencing consider that the difference with face-to-face discussion is small. 2. A Moiré pattern may occur in a gradation picture. 3. The availability of distributed and synchronised discussions with cloud computing type VR is high.

This slide is presented in CAADRIA2011 (The 16th International Conference on Computer Aided Architectural Design Research in Asia).
Abstracts: Acquiring current 3D space data of cities, buildings, and rooms rapidly and in detail has become indispensable. When the point cloud data of an object or space scanned by a 3D laser scanner is converted into polygons, it is an accumulation of small polygons. When object or space is a closed flat plane, it is necessary to merge small polygons to reduce the volume of data, and to convert them into one polygon. When an object or space is a closed flat plane, each normal vector of small polygons theoretically has the same angle. However, in practise, these angles are not the same. Therefore, the purpose of this study is to clarify the variation of the angle of a small polygon group that should become one polygon based on actual data. As a result of experimentation, no small polygons are converted by the point cloud data scanned with the 3D laser scanner even if the group of small polygons is a closed flat plane lying in the same plane. When the standard deviation of the extracted number of polygons is assumed to be less than 100, the variation of the angle of the normal vector is roughly 7 degrees.

Visual Environment by Semantic Segmentation Using Deep Learning: A Prototype ...Tomohiro Fukuda
This document describes a proposed method for estimating sky view factor (SVF) using semantic segmentation with deep learning networks. Specifically:
- It develops a system using SegNet and U-Net deep learning models to perform pixel-wise semantic segmentation of sky and non-sky areas from images to calculate SVF ratios.
- The system was trained on 300 manually segmented images and tested on 100 fisheye photographs, achieving 98% accuracy in estimating SVF under different sky conditions.
- Future work is needed to apply the system to live video streams rather than static images. The method provides an efficient, high-precision way to estimate important urban environmental metrics like SVF.

Computational visual simulations are extremely useful and powerful tools for decision-making. The use of virtual and augmented reality (VR/AR) has become a common phenomenon due to real-time and interactive visual simulation tools in architectural and urban design studies and presentations. In this study, a demonstration is performed to integrate structure from motion (SfM) into VR and AR. A 3D modeling method is explored by SfM under real-time rendering as a solution for the modeling cost in large-scale VR. The study examines the application of camera parameters of SfM to realize an appropriate registration and tracking accuracy in marker-less AR to visualize full-scale design projects on a planned construction site. The proposed approach is applied to plural real architectural and urban design projects, and results indicate the feasibility and effectiveness of the proposed approach.

This slide is presented in CAADRIA2010 (The 13th International Conference on Computer Aided Architectural Design Research in Asia).
The purpose of this study is development of a tool by which citizens who are non-specialists can design a regional revitalization project. Therefore, a 3DCAD/VR (3-Dimensional Computer Aided Design/Virtual Reality) combination system was developed by using SketchUP Pro, GIMP, and UC-win/Road. This system has the advantages of low cost and easy operation. The utility of the system was verified as a result of applying the developed prototype system in the Super Science High School program for high school students created by the Ministry of Education, Culture, Sports, Science and Technology, Japan. It has been used for two years, since 2007. In addition, the characteristics of the VR made by the non-specialists were considered.

addressed, and the continuous study method using VR and a blog is shown. Then, evaluation
is conducted by considering an actual design project as a case study. Furthermore, VR
functions needed through the case study are developed. Using this method, a small patio
on which parasols were permanently and lawfully set up on a road lot was completed.

This ppt is presented in CAADRIA2008 (The 13th International Conference on Computer Aided Architectural Design Research in Asia).
As a method of dissemination of environmental symbiosis design towards
environmental problem solutions, 3DCG pre-rendering animation (3DCGPRA) which has
a high quality of representation and has a powerful appeal, is expected to be particularly
effective. After arranging components required in an environmental symbiosis design, the
representation targets which needed to be developed were clarified. In addition,
representation methods of shade and shadow, grass, human activity, and symbiosis methods
etc. were developed. In a real project, a 7’ 3DCGPRA was created applying these new
methods, and its validity was evaluated.
