【摘要】 针对现在图形数据量越来越大,现有的硬件水平对大规模图形数据处理的限制,提出了一种基于高程熵的大规模地形建模方法,使得大规模地形数据的处理效率得到显著的提高。首先介绍了传统的地形建模方法,然后从“建模速度”和“建模精度”两个方面入手,论述了大规模地形的建模方法和思路。最后通过几个实际的例子对本文的建模方法进行了验证,证明了本文建模方法的正确性和有效性。更多还原

【Abstract】 Aimed to the more massive data of graphics and the limitation of the hardware capability,a modeling method of massive terrain is presented based on elevation entropy.The traditional modeling method of terrain is introduced at first,then the proposed method in detain from two aspects of modeling velocity and modeling precision is dicussed.Examples prove that the method is correct and valid.更多还原
