今回我々は OpenSimulator のアーカイブデータであるOARファイルをUnityに読み込ませるための変換システムの開発を行った.これにより,OpenSimulator を共有開発環境とし,Unityを通して容易に3次元空間の可視化データの作成が可能になった.We developed a conversion system to load OpenSimulator Archive (.oar) files into Unity. This system allows the user to load world data jointly created in OpenSimulator into Unity on a region-by-region basis, and to ultimately output the data from Unity in a variety of formats. These features allow us to treat the pairing of OpenSimulator and Unity as a shared development environment, which simplifies the low-cost creation of 3D spatial visualization data
