纹理映射技术是当前计算机图形学中的一个热点问题。提出了一种基于四叉树结构的海量数据纹理映射算法。对多分辨率纹理数据进行了有效的压缩存储,并利用纹理映射误差,有效地减少了实时仿真过程中纹理数据调度的数据量,同时优化了内存释放算法,减少了内外存数据之间的反复调度,从而解决了大规模地形场景重建过程中的数据调度与海量数据的纹理映射问题。

Texture mapping is an important element for the representation of three dimension terrain generation and a hot topic in the field of computer graphics.A mass texture mapping algorithm on the basis of quadtree is proposed in the paper.The texture data size is remarkably reduced by using the multi-resolution texture data compression technology and texture mapping error technology.And also the memory release algorithm is optimized to reduce the schedule times remarkably.So the data schedule and mass texture mapping problems of the large scale scenes reconstruction are solved.
