app is a tiny app to convert images to ElevationGrids
drag and drop a .gif, .jpg, or .bmp onto the app, wait a sec, and out pops a new .wrl file.
currently app frowns upon spaces in the path to the image file, so make sure the image you drag onto the app comes from somewhere like C:\images\, and not C:\Documents and Settings. app itself can be anywhere on your hard drive.
