视觉优化的移动三维图形自适应重构技术研究

摘要

In order to generate the satisfactory visualization results on mobile terminal,adapt different hardware environment and software requirements,an adaptive rendering approach of hierarchical model selection based on the visual importance is proposed.The distribution ratio of the different levels of LOD (levels of detail) model is adjusted according to the importance of visual objects in the scene,meets the requirements of limiting calculation mechanism,and good stability of generation time for scene is maintained.An experimentation in dynamic scene is presented to enhance the scene rendering speed effectively based on ensuring the scene realistic visualization.Consequently,the study offers the compromise solution for the cost of graphics rendering on mobile terminal and visual effects.%为保证移动终端上生成满意的可视化结果,适应不同软硬件环境的要求,提出了一种基于视觉重要性的模型分层选择自适应绘制方法.该方法根据场景中对象的视觉重要性,自动调节不同级别细节层次模型的分布比例,满足限时计算机制的要求,使场景的生成时间保持较好的稳定性.在动态场景中对该方法进行的实验结果表明,该方法能在保证场景可视化真实感的基础上,有效提升场景的绘制速度,为移动终端图形绘制成本和视觉效果提供了一种折中解决方案.
