| + | |||
| + | The Rhino feature that I have been working with the most is the Heightfield map generator command. | ||
| + | |||
| + | It took me a while to figure out that this command is not best used with just a bitmap image taken with a digital camera. I learned that making a real heightmap (I used the shape-from-shading filter in GIMP) and saving it as a bitmap is the way to go. | ||
| + | |||
| + | 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: | ||
| + | |||
| + | Just a bit of Gaussian blur of the image before using it in Rhino 3.0 helps smooth out the few rough edges. | ||
| + | |||
| + | I recently uncovered a better heightmap maker than GIMP. It is a Photoshop plug-in from CGSD that is part of their Bump Texture Tools package. It is called //Shape from Shading//. | ||
| + | |||
| + | The CGSD package also includes a stereo image inverter. | ||
| + | |||
| + | The GIMP program makes heightmaps OK but GIMP's shape from shadow filter was written for a satellite, and that won't help most of you. | ||
| + | |||
| + | The CGSD plug-in for Photoshop is much more general in its application. See this site: www.cgsd.com/ | ||
| + | |||
| + | Another good preprocessing program is the shadow reduction filter plug-in for Photoshop, [[http:// | ||
| + | |||
| + | This works well on the original image before converting it to a heightmap with the CGSD filter shape from shading. | ||
| + | |||
| + | 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. | ||
