This is a WebGL viewer for diffusion curves images for Firefox and Chrome*. * for security reasons, Chrome do not let you access local files, so only the drag and drop will work (and without textures for the Apple and Lily examples). To make it work on Chrome, you need to either open Chrome with the "--allow-access-from-files" flag or host the web page on a local web server and access it via http://localhost/.../dc_viewer.html.
