Real-Time Shadow Research in Virtual Environment with Higher Complexity and Larger Shadow Regions

In this paper, based on visible differences of real-time shadow in virtual environment with higher complexity and larger shadow regions, comparison and combination of hard shadow operators and soft shadow operators are made possible. On the basis of perceptual psychology and vision, we present the model of real-time shadow processing in virtual environment with higher complexity and larger shadow regions, and that have verified the proposed ideas by means of the experiments.
