阴影锥法生成阴影 volume shadow
The main work of this dissertation is concentrated in following three aspects:1. In shadow generation, the shadow map algorithm is optimized based on projection distance, so the visual effects of traditional algorithm is improved.
主要工作集中于以下几点:1.在阴影生成方面,提出基于投影距离的阴影图算法,对传统软阴影生成算法的视觉效果进行了改进,使得软阴影的模糊程度和阴影的投影距离相关,在保证渲染效率的基础上得到了视觉上更加真实的阴影效果。
