float min_lon = rint(detail(1,"min_lon")); 问题2)建uv坐标映射成纬度最大最小值建坐标属性 解决方案) 1)使用uv Texture产生uv坐标属性 现在有了uv相对坐标属性 2)将uv坐标范围映射成“经纬度最小最大范围” float lon = fit01(v@uv.y,min_lon,max_lon); float lat = fit01(v@uv.x,min_lat...

Every line of the UVG is part of a great circle (equator) that divides the sphere of Earth in half. This is the major change that Bill Becker and I made to the “planetary grid’ model (shown here) proposed in the 1970s by three Russian men Makarov (an engineer), Morozov (a lingu...
