In Virtual Reality(VR), virtual worlds are mainly created by computer graphics, which is not completely realistic when it is used to describe the existing real world. The best way to do this, therefore, is to create a virtual world with images captured by cameras. For interactive response, which is essential for VR, the system needs to change the image being displayed according to where the human operator, whom we call as a virtual viewing point, is viewing from. In other words the system has to deal with the occlusion problem, which is mainly caused by motion parallax. This paper proposed a solution to the occlusion problem. It introduces scenery planes which sample the real world as flat planes based on the assumption that these planes are sufficient to represent the world while the virtual viewing point is moving. There are two types of scenery planes: far planes, which do not need to consider depth during movement, and near planes, which do need to consider depth. The method is verified by a prototype system with stereoscopic viewing ability.
