Here are some images to give you a feel for what Rayshade can do.
Follow the thumbnail icons or titles to see the full images (in compressed
JPEG format), or use the .ray files to see the source code used to
generate these images. Full 24bit color images and complete animations are
also available in Utah Raster Toolkit [URT] format, but be
forewarned: URT files may be over 10 times larger than the JPEGs, and
your display tool may not understand them anyway.
This page has lots of images: a text-only page is also available.
