摘要
针对增强现实应用中的复杂三维场景实时渲染问题,提出一种结合GPU加速的连续多细节层次(Levels of Detail,LOD)模型优化方法,以便提供更加流畅的用户感官体验。该方法采用并行局部处理架构,每个网格区域的生成均不依赖于已存在的其他网格,因此三维场景生成不使用任何层次结构,十分适合基于GPU的LOD处理,并且具有高度可扩展性。测试结果表明,相比其他模型优化方法,所提优化方法在流畅度方面表现出更好的性能,有效增加了场景模型的实时性。
Aiming at the real.time rendering problem of complex 3D scenes in augmented reality application,a continuous levels of detail(LOD)optimization method combining graphics processing unit(GPU)acceleration is proposed to provide more smooth sense experience for users. The parallel local processing architecture is adopted in the method,and each mesh region is generated independently of other existing meshes. 3D scene generation does not use any hierarchical structure,is very suitable for GPU- based LOD processing, and has high scalability. The test results show that, in comparison with other model optimization methods,the proposed optimization method has higher performance in term of fluency,and can enhance the real. time performance of the scene model effectively.
