A Digital Twin is defined as a digital replica of a real entity in the physical world. In this study, the Digital Twin simulation is developed for connected and automated vehicles (CAVs) by leveraging the Unity game engine. A Digital Twin simulation architecture is proposed, which contains the physical world and the digital world. Particularly, the digital world consists of three layers, where the Unity game objects are built to simulate the "hardware", the Unity scripting API are used to simulate the "software", and external tools (e.g., SUMO, MATLAB, python, and/or AWS) are leveraged to enhance the simulation functionalities. A case study of personazlied adaptive cruise control (P-ACC) is conducted to showcase the effectiveness of the proposed Digital Twin simulation, where the ACC system can be designed to satisfy each driver's preference with the help of cloud computing.

Digital twin technology based on building a virtual digital city similar to a real one enables the simulation of urban phenomena or the design of a city. A geospatial platform is an essential supporting component of digital twin cities. In this study, we propose a planetary-scale geospatial open platform that can be used easily in the most widely used game engine environment. The proposed platform can visualize large-capacity geospatial data in real time because it organizes and manages various types of data based on quadtree tiles. The proposed rendering tile decision method provides constant geospatial data visualization according to the camera controls of the user. The platform implemented is based on Unity3D, and therefore, one can use it easily by importing the proposed asset library. The proposed geospatial platform is available on the Asset Store. We believe that the proposed platform can meet the needs of various three-dimensional (3-D) geospatial applications.

Haji merupakan rukun Islam yang kelima yang wajib dilaksanakan oleh seorang muslim yang telah mampu melaksanakannya. Manasik haji pada dasarnya adalah memberikan pelajaran atau informasi mengenai tata cara melaksanakan ibadah haji, sehingga tidak hanya terbatas pada calon jama’ah haji, biasanya masyarakat beragama muslim mempelajari tata cara melaksanakan ibadah haji dengan menggunakan buku-buku atau dengan cara memperagakan langsung dengan cara mensimulasikan tata cara ibadah haji sesuai dengan kondisi yang sebenarnya. Namun banyak kalangan masyarakat muslim yang enggan mendalami manasik haji, dikarenakan beberapa hal seperti tidak adanya waktu, dan kurangnya minat mempelajari dikarenakan kurang menarik dan tidak praktis. Dari hal tersebut sehingga muncul ide untuk membuat aplikasi simulasi manasik haji berbasis virtual 3D, aplikasi ini berisi tentang simulasi untuk rukun haji. Aplikasi manasik haji berbasis virtual reality ini dirancang dan dibuat dengan menggunakan software 3Ds Max dan unity 3D Game Engine. Hasil penelitian berupa aplikasi manasik haji yang dapat menampilkan simulasi virtual reality, yang meliputi simulasi tiba di bandara, Wukuf di Arafah, Mabit di Muzdalifah, Mabit di Mina, Jumrah, Tawaf, Sa’i dan simulasi Tahallul. Dengan adanya aplikasi ini diharapkan akan terjadi peningkatan minat masyarakat dalam mempelajari tata cara pelaksanaan ibadah haji.Kata kunci : virtual reality, manasik haji, simulasi, 3D.
