摘　　要：针对三维交互场景中受到数据量限制等多方面因素,导致难以实现完整场景阴影无损渲染问题,提出一种面向三维交互场景的实时阴影渲染方法。充分考虑三维交互场景对阴影渲染的实际需求,研究不同空间分辨率下阴影渲染精细度,从阴影形成条件和过程出发,建立光照模型,分析光照变化条件和着色差异等变量下的阴影形成结果,构建多细节层次模型,在线模型渲染的基础上,利用点模型进一步填补线模型阴影条件下的空隙,完成阴影渲染。经过实验证明所提方法的渲染性能良好,保证视觉条件下的连续性,渲染时间短、效率高,用户感知评价好。A real-time shadow rendering method for 3D interactive scenes is proposed to address the problem of difficulty in achieving lossless rendering of complete scene shadows due to various factors such as limited data volume.On the basis of fully considering the actual requirements for shadow rendering in 3D interactive scenes,we researched the fineness of shadow rendering under different spatial resolutions.And then,we built a lighting model based on the formation conditions and processes of shadow.Meanwhile,we analyzed the shadow formation results based on the variables such as lighting conditions and coloring differences.Moreover,we constructed models at multiple level of details.Based on the line model rendering,we used a point model to further fill the gaps of the line model under the shadow conditions,thus completing the shadow rendering.The experimental results show that the proposed method has good rendering performance and ensures the continuity under visual conditions,with short rendering time,high efficiency and good user perceptual evaluation.
