用裁剪纹理方法处理大纹理实时交互的研究

Research on large texture real-time interaction by clipping texture

讨论了裁剪纹理(Cliptexture)技术。该技术利用在有限物理内存中缓存大纹理数据的子集实现动态纹理显示。描述了裁剪纹理的静态结构和形成,对裁剪纹理数据调度过程的缓存预测、纹理环行装载,以及动态纹理装载控制进行了阐述。最后通过存储效率分析说明了该技术处理大纹理数据的有效性。

The cliptexture technique displays the dynamic large texture by caching the subset of texture data in finite physical memory. The anatomy and forming of the cliptexture are described. The look-ahead cache, toroidal loading and control of dynamic texture during the scheduling of the cliptexture are discussed. Finally, the effectiveness of Cliptexture in handling much larger texture is proved by analyzing the storage efficiency.
