摘　　要：针对基于GPU的动态地形可视化算法中地形形变处的纹理映射问题,提出了在片元着色器里对多种纹理样本进行采样,以动态地形模型本身特点为纹理生成条件,以地形深度偏移图作为动态地形纹理分布alphamap图的动态地形过程纹理生成和映射方法。通过典型的弹坑和车辙纹理映射实验,验证了该方法的正确性和有效性。Aiming at the texture mapping in dynamic terrain visualization method based on GPU,a new dynamic terrain procedural texturing method based on GPU is proposed.The algorithm takes multiple sample textures in the fragment shader,and then use functions as constrained condition and terrain depth offset map as alphamap.At last,the crater and ruts texturing experiments prove that the method is corrective and valid.
