![]() ![]() ![]() A rhino’s horn is made of keratin, the same material that makes up our fingernails and hair. The word rhinoceros comes from the Greek words rhino (nose) and ceros (horn). The rhinoceros gets its name from its most famous feature: horns. Their ears can move independently of each other, and one may be cocked forward while the other is directed backward, or both may perk straight up when an interesting sound that requires total concentration is detected. This defense mechanism has given them an undeserved reputation for having a bad temper. Rhinos soak in mud or roll in dust as protection against sunburn and insect bites.īecause rhinos are very nearsighted, they often charge when startled in the wild, rhinos have been observed charging at boulders or trees. Their thick skin acts like protective plating but is sensitive, as the blood vessels are close to the skin’s surface, and can be easily scarred. What all rhinos have in common are one or two horns, a broad chest, thick skin, poor eyesight, excellent hearing, and a fondness for rolling in the mud. ![]() Today, only five species continue the line: two native to Africa and three native to Asia. Throughout the eons, close to 100 known rhinoceros species have existed. One of these ancestors, the paraceratherium, was 25 feet (7.6 meters) long and 18 feet (5.5 meters) high at the shoulder, the largest land mammal ever known. The rhino’s lineage is an ancient one-its ancestors walked the Earth 55 million years ago. Yet most of the time this fearsome creature is content to browse peacefully on vegetation. In our imaginations, the rhino is the embodiment of brute strength. Its eyes peer from a massive head that tapers to that battering ram of a horn. Its heavyset body stands on sturdy legs like tree trunks. Substitute any number between 0 and 100 for the 90 in the example to change the transparency of the planes.Ambassadors from another age: The rhinoceros looks as though it has lumbered into our time from some primeval era. For example, turning off backfaces allows images to be placed on all sides of an object without obscuring the view.īelow is a command macro that can be added to a button or command alias to automate the process of applying the image and display modes to the planes in V4. It may also be useful to set up a special display mode in v4 with settings that are tweaked more than you would typically want them to be in a standard render mode. It may be useful to place picture frames on separate layers so they can be selected, locked, or hidden easily. These can be adjusted to preset levels using the Material Texture and Material Transparency toolbars. Transparency and image intensity would be the most useful to adjust. Adjust image intensity in the Properties> Material page. The Orient command can be used to scale and align points on the image to known dimensions and locations. Once set up, the planes can be adjusted like any other object in Rhino with transform commands to align and rotate them as needed. Three PictureFrame planes set up to display reference images. You must use the command again to see textures in any other viewport. Note that the object display mode is set in the current viewport when the command is run. This second method may be more useful since it allows the plane to be displayed with the image no matter how the viewport display is set. These modes must be set in the viewports or use the SetObjectDisplayMode command to set per object display modes. The setting to show object materials is on the top level page of the mode under Shading settings> Color and material usage.) The rendered mode is set this way by default, but it is possible to make new modes that have this set as well. Since this is a material channel, it is only displayed in the viewport when in Rendered viewport mode or, in V4, some other display mode that shows material (Options>Appearance>Advanced Settings. The plane has a Basic material assigned and the image is in the texture channel. You can see this texture assignment in the plane's object Properties >Material page. The plane is automatically assigned the image as a texture map, the image being mapped to the surface UV. The first point picked for the plane corresponds to the lower left corner of the image, the second to the lower right, and the third pick places the top edge. Note that the plane can be any size but is constrained to being of the same aspect ratio as the image. Once you select the image, you are prompted to place the plane as in the Plane 3Point command, with a Vertical option. Start the PictureFrame command (Surface toolbar>Planes flyout>PictureFrame, or type PictureFrame and Enter.) You will see the File Open dialog as Rhino sends you off to locate the image you wish to use. ![]()
