![]() In the exercises, you will use Rhino’s navigation tools, shaded preview, render, and use some basic object manipulation. If you have never worked with 3-D computer modeling before, Getting Started with 3D, A Designer’s Guide to 3D Graphics and Illustration, by Janet Ashford and John Odam is one of several excellent books that will help you learn some of the terminology and basic principles of 3-D design on computers. If you have experience using a 3-D modeling program, the following exercises may seem simple, but they will help you understand Rhino’s interface and navigation tools. By rendering you can add color, texture, shadows, and lights. When you have a view you like, you can render the view. ![]() You can do this in both a wireframe view and a shaded view. You can manipulate the views and look at your model from different angles easily by dragging with your right mouse button. Rhino provides tools to help you do this. Your First Look Working in 3-D on a computer requires that you visualize three-dimensional objects drawn on a two-dimensional medium- the computer screen. For additional information on Rhino features go to page 66. Rhino can create polygon mesh objects that approximate the NURBS objects to export to those programs. Polygon mesh objects are used by some programs for rendering and animation, stereolithography, VRML, and finite element analysis to approximate a smooth surface. Rhino’s Geometry Types There are five fundamental geometric objects in Rhino: points, NURBS curves and surfaces, and polygon meshes. Because of their flexibility and accuracy, NURBS models can be used in any process from illustration and animation to manufacturing. NURBS Non-uniform rational B-splines (NURBS) geometry is a mathematical representation that can accurately define any shape from a simple line, circle, arc, or box to the most complex 3-D free-form organic surface or solid. You are free to create the model any way you want. With Rhino, you can create free-form curves, surfaces, and solids. You can model and render objects that you could previously create only using software and hardware many times more expensive. Rhino provides a flexible, accurate, and fast working environment. With Rhino you can model anything from a heart valve to a ship hull and from a mouse to a monster.
