交互式数字地形合成算法

针对当前手工建模费时费力和自动算法难以调整合成结果的问题,提出一种基于示意图的交互式地形合成算法.通过使用用户绘制的示意图来解决地形特征的精确放置问题,并利用控制参数来调整合成地形的细节,在自动化和控制性上达到了较好的平衡.实验结果表明,该算法能快速生成地形,且可以方便地对生成的结果进行调整;即使是缺乏专业建模技能的用户也能使用该算法生成满意的地形,对于地形建模从手工到自动化的转变具有一定的促进意义.

An Interactive Terrain Synthesis Algorithm

In existing procedural synthesis methods,manual terrain modeling is a laborious process,which is always difficult to adjust results.To solve these problems,an interactive method based on sketch map is proposed.Utilizing a user-drawn sketch map to exactly control the placement of terrain features,and some control parameters to adjust details of synthesized terrain,the proposed method reaches a good balance between automation and controllability.Experiments show that terrain is synthesized efficiently,and the synthesis result can be controlled conveniently by the users,who may even lack of special modeling skills.To a certain extent,it accelerates the transition from manual to automated terrain modeling.
