Light field algorithm is one of the most famous image-based rendering techniques. In this paper, an improved light field algorithm - sphere light field algorithm - is proposed. This new algorithm replaces the parallel planes used in traditional light field algorithms by a triangularly parameterized sphere surface. Comparing to the traditional light field algorithms, this new algorithm achieves a more uniform distribution of light slabs in the three dimensional space. This improves the quality of the rendered images. Using the triangular parameterization and subdivision of the whole light field, less calculation and less memory are needed, resulting in improved real-time rendering.
