High resolution 2D video content in High Definition or higher resolutions has become widespread and video playback of such media in immersive virtual environments (VE) will be a valuable element adding more realism to VE applications. This kind of video playback, however, has to overcome several problems. First, the data volume of video clips can reach up to hundreds of gigabytes or more depending on the length of the clips, and the data has to be streamed into virtual reality (VR) systems in real-time. Second, the interactivity of the playback screen in 3D virtual environments requires efficient rendering of each video frame. Interactivity means that the plane of the video playback screen needs to rotate, translate, and zoom in and out in 3D space as the viewer roams around in the VE. This also means that the video is not necessarily parallel to the display screen but will need to be displayed as a general quadrangle. In this work, we propose an efficient algorithm that utilizes m...
