混合场景中光照一致性研究

Research of illumination consistency in hybrid scene

在基于本地与远程绘制的混合场景中,为了实现本地绘制场景与远程绘制场景的无缝融合,光照一致性是必须解决的问题。在服务器端绘制所需的复杂背景,在移动终端绘制交互对象,并在场景中使用相同的光照模型。在融合阶段利用服务器端所传递的光照参数对本地移动终端的光照模型进行光照重计算。利用时间插值的方法来模拟一天中环境光的变化情况,并对本地移动终端中的光照模型进行二次重计算。实验结果表明,通过上述方法,在移动终端上实现了不同场景的无缝融合。该方法用于移动终端的场景融合时具有较高的绘制效率与可行性。

Illumination consistency is a problem that must be addressed to reach the seamless integration of local rendering scene and remote rendering scene in a hybrid scene of local and remote rendering. This paper was aim to address the illumina- tion consistency problem. Firstly, it drawn the complex background on the server and drawn the interactive objects on the mo- bile terminal. While drawing the same illumination model was used. Secondly, it used the illumination parameters transmitted by the server to recalculate the illumination parameters for the illumination model on the local mobile terminal in the integration phase. Lastly, used the time interpolation method to simulate the changes of the ambient light during the day and recalculate the illumination model on the local mobile terminal. The experimental results show that, through the above method, the seamless in- tegration of scene can be realized on the mobile terminal. The mothed used for the integration of scene has the high rendering efficiency and feasibility.
