In Rhino 4.0 Essential Training, author Dave Schultze shows how the 3D NURBS-based modeling tools in Rhino 4.0 are used to engineer products from toy robots to full-sized aircraft. This course concentrates on using Rhino 4.0 for industrial design and rapid prototyping, with a review of common 3D terminology using specific examples. Along with a comprehensive exploration of the Rhino interface, the course includes an introduction to building 3D objects with Rhino's three primary entities: the curve, the surface, and the solid. Exercise files are included with the course.
Now let's take a look at the variety of Display modes for each Viewport. Like in many Rhino commands, you can access these in several ways, as well as using keyboard shortcuts. The menu location is under View at the top of the interface, but you probably want to focus on the Viewport label for quick access, so let's start there. All of these Shading modes are accessible via the Viewport label, right-click, and they are all located at the top. Right now, we are in Wireframe view. This is probably the most common view, doesn't provide a lot of feedback, but this will be extremely helpful when you've got enormous scenes and want a quick refresh.
Let's switch it over to Shaded mode. This gives you flat colors and lines, and in this case, the color is coming from its layer. So, I am going to go down to the layer option here at the bottom and we can see that the cylinder is on a blue colored layer. Everything else is on a black layer. So, it's going to appear as a shade of gray. We'll cover more about layers in the Workflow chapter. Next mode up we'll take a look at is Rendered. Now here, the color of every object in the screen is going to be based on its material it's been assigned.
But since we have assigned no materials, we're just going to get this neutral, flat gray. The next mode is Ghosted, one of my favorites. This allows you to see through objects. It kind of highlights the surfaces but also shows edges and curves pretty clearly. So, this is extremely handy when you have objects or geometry with internal components. You can verify that things will fit and parts don't poke outside where they are not supposed to. Okay, and then closely related is the X- Ray, and this is just more flat surfaces with emphasis on just edges and curves.
So, it's a little more abstract. Finally, the next two options are more of toggles than modes. So, we're going to click on Flat Shade, and that takes the last mode and just flattens everything out, and we can see that demonstrated here in this flattened sphere. Rounded objects become very faceted so it's probably something that doesn't look too good, but it does increase the speed for large complicated scenes. So, let's turn that toggle back off and check the final toggle. This is called Select Objects Only.
And this can actually be a little confusing if you don't realize you've selected it. Everything looks like its in Wireframe mode, but actually, you're in a view where only those objects that are selected will get shaded. So, you have to select them for them to show up. Probably want to turn that back off, and I recommend actually keeping Shaded mode. This seems to me to provide the best feedback for visualizing a 3-dimensional scene. I further recommend that you have all the layers typically as black so that we get a nice, neutral gray.
I think that's a great way to be more focused on the form, and therefore your design, as opposed to being distracted by colors. We'll cover more on layers, including changing the colors, in the Workflow Basics chapter. So, the Viewport Shading modes can be a huge aid in speeding workflow and avoiding errors, even though you will probably settle on just two or three preferred modes. Keep in mind there are also free plug -ins that can customize these modes even further.
