摘要
针对三维地形晕渲的具体需求和存在问题,提出了一种基于色层图与纹理融合的晕渲方法。根据自定义或色层表主色调插值生成色彩连续的色层图,对地形高程进行着色;在地表材质分块的基础上,通过计算相邻材质边界上的多重纹理坐标,使用多重纹理映射进行融合过渡;最后给出了实验结果。
The paper proposed a layered color map and texture blending based terrain shading method.First,the terrain grids were colored by the layered color map,which could be generated by customized settings or interpolated by existing layered color tables main hue.Secondly,by terrain material area division,the multi-texture coordinates were calculated,and the textures represents differ- ent details were blended to get smoothly translation.The experiments show the arithmetic results.
