Research and Implementation of Optimization Techniques Based on a Hierarchical Structure for the Multi-light Source
Multi-light source optimization techniques is a technique to improve the rendering time for many-light source.Lightcuts1 is a classic algorithm and can handle complicated scenes and get very good result with faster speed.In this paper, we made an improvement to the algorithm for the artifacts of soft shadows.In our method, we select more than one representative of lights in light clusters and choose one light as the representative randomly during the rendering process.The experimental results show that this method can effectively improve the quality of soft shadows.
