Tools for constructing pseudo-3D space on the WWW using images
Recently, due to advancements in virtual reality and computer graphics technologies, a virtual space that looks as real as a real space has been constructed. Accordingly, there are many studies that employ virtual spaces to support human communication and remote working. Until now, the virtual space employed by these studies has been composed of geometric models. Since the real space is very large and there are a lot of objects in the real world, the cost of modeling the real space is very high. In our previous paper,(10)) we proposed a method for building a virtual space using image data, named the image based non-rendering (IBNR), in order to cut down the cost. In this paper, we explain the design and implementation of the tools which we implemented to construct virtual spaces based on IBNR. With these tools, it is easy to construct and renew a large-scaled virtual space based on the real space.
