摘要： 提出一种新的高效的大规模三维地貌纹理合成方法。把三维地貌场景进行透视变换投影到平面上，对这些平面上的三角网格赋一个连续的缩放因子场，把给定的纹理缩放成很多级别，使得可以和网格上的缩放因子相对应，按二维平面三角面片纹理合成的思想进行合成。实验表明，该方法在不拉伸纹理的同时能够达到实时，取得良好的视觉合成效果。

Abstract: This paper presents a novel real-time texture synthesis algorithm on large scale 3D physiognomy surface. The algorithm contains three stages. it projects the 3D surface onto 2D plane, gives every triangle grid a scale factor which describes what kind of texture to use, synthesizes texture over 2D plane using mip-mapped texture sample. Experiments show that this algorithm can produce very nice real-time results.

Key words: texture synthesis, scale factor, large scale scene
