-When the real heightmap of the image is imported into Rhino 3.0 and the Heightfield from image command is used on that, the result is a very detailed and accurate [[rhino:​nurbs|NURBs]] surface of the terrain.+When the real heightmap of the image is imported into Rhino 3.0 and the Heightfield from image command is used on that, the result is a detailed and accurate [[rhino:​nurbs|NURBs]] surface of the terrain.
  
 Just a bit of Gaussian blur of the image before using it in Rhino 3.0 helps smooth out the few rough edges. Just a bit of Gaussian blur of the image before using it in Rhino 3.0 helps smooth out the few rough edges.

 This works well on the original image before converting it to a heightmap with the CGSD filter shape from shading. This works well on the original image before converting it to a heightmap with the CGSD filter shape from shading.
  
-When these two preprocessing filters ​are used, the level of detail in terrain maps generated with your Heightfield command is infinitely better than just using a regular digital camera photo image without any preprocessing.+When you use these two preprocessing filters, the level of detail in terrain maps generated with your Heightfield command is infinitely better than just using a regular digital camera photo image without any preprocessing.
