Using Extrude and Spin to create a Wine Glass

A classic staple of introductory modeling examples is a 3D model created by spinning the profile around a single axis. And for good reason. The process is simple enough to be done quickly while also giving you a clear understanding of a 3D program’s way of working and “thinking.” As such, it would be remiss of me not to include such an example here. To create this model, most of the heavy lifting is done with Blender’s Extrude operator, but the magic comes together when you use the Screw modifier. »

Unwrapping Your Eye and Painting a Detailed Texture

In preceding tutorial, I show you how to add basic materials to an eyeball model (created in the eye modeling tutorial). While the model looks pretty good, you can provide an additional splash of realism to it. In particular, you can get a much more detailed iris, and you can add some of the fine blood vessels around the white section of the eye. Those kinds of details are difficult to pull off with just material shaders and vertex colors. »

Coloring the Eye

If you followed the eye modeling tutorial, you should have a model of an eye that has the boring, plastic default gray material. If you haven’t modeled that eye, don’t worry; it’s right here. Feel free to download it if you need a starting point. The purpose of this tutorial is to make that eye look more like an actual eye and less like a gray ball. Setting up a Materials screen for BI When working with materials in Blender — particularly when rendering with BI (Blender Internal) — you find out very quickly that you often have to scroll the Properties editor or you frequently have to switch between different sections of the Properties editor. »

Modeling an Eye

If you’re modeling characters, chances are good that those characters are going to need eyes. Granted, there’s a chance that all your characters may be robots, moles, and worms, but I’ll assume that’s not the case. Eyes carry the life of a character, so you want to get them right. This example walks you through producing a nice eye model that you can make quickly and even reuse in future projects. »

Creating a Simple Model with Extrude and Inset

Although Ctrl+left-clicking for quick extrusion (as described in Chapter 4 of Blender For Dummies, 3rd edition) is convenient for creating rough models to start with, extruding by pressing E certainly has workflow benefits. The biggest benefit is the quick access to your other transform tools. Combined with Blender’s Inset operator (I), there’s some really powerful modeling that you can do. To illustrate the benefits of these tools, use the following steps to model a skyscraper from a single plane: »
