Description | Free-viewpoint rendering has always been one of the key motivations of image-based rendering and has broad application prospects in the field of virtual reality and augmented reality (VR/AR). The existing methods mainly adopt the traditional image-based rendering or learning-based frameworks, which have limited viewpoint freedom and poor time performance. In this paper, the cube surface light field is utilized to encode the scenes implicitly, and an interactive free-viewpoint rendering method is proposed to solve the above two problems simultaneously. The core of this method is a pure light ray-based representation using the cube surface light field. Using a fast single-layer ray casting algorithm to compute the light ray’s parameters, the rendering is achieved by a GPU-based three-dimensional (3D) compressed texture mapping that converts the corresponding light rays to the desired image. Experimental results show that the proposed method can real-time render the novel views at arbitrary viewpoints outside the cube surface, and the rendering results preserve high image quality. This research provides a valid experimental basis for the potential application value of content generation in VR/AR. |
