Having already learned the basic concepts about how 3D objects are represented in the computer, and how they are turned into real objects with 3D printing, this class will focus on workflows and more advanced modeling concepts. We will select some of the most flexible tools to get you started making amazing models without spending too much time figuring out new interfaces. The modeling operations are shared with other applications, so the focus of this class is on the concepts involved more than the software.

The workshop portion of this class will use Wings3D and Meshlab. Wings3D has fairly simple modeling tools, but also has some more advanced features so it will still be useful as you gain experience. There are two main strengths of the program that will be taught and demonstrated in this class. The first is topologically oriented subdivision modeling, which is a way of describing one family of techniques that designers often use to create the fantastically complicated lattice-like structures often seen in 3D printing. The second is coloration, which includes texture mapping (images) and embedded color (face and vertex coloring).

Exercise one - Topological Subdivision Modeling: Starting with a basic model, either a geometric primitive, an original form, or one imported from other software, we will explore the different methods of modifying and adding detail in ways that take full advantage of the capabilities of 3D printing to created intricate forms and strong, lightweight structures. We will discuss concepts of topology and complexity in 3D design so that you can make the best use of the techniques in a useful, practical way. Anyone interested in creating "Math Art" will benefit greatly from this exercise and will make some awesome models to print.

Exercise Two - Full Color Models: We will start by learning the different ways that color can be stored on a model, and when to use each method. We will create a basic UV texture-mapped model and explain the process of making it printable at Shapeways. The second portion of this exercise will outline some very intuitive methods of applying color directly to the model without using external texture images. These techniques are a powerful way to quickly get going with color models and avoid any trouble in modifying, uploading, or printing your model. Aside from being a lot of fun, these techniques are very well suited to creating full color landscapes, architectural models, characters and vibrant, detailed sculpture. We will also review coloring in Meshlab, another quick and easy way to make great looking models for printing in Full-Color Sandstone.

Exercise Three - Photographic 3D capture: It is now possible to create a 3D model automatically from photographs of an object! Getting good results can be tricky, and the model will need a lot of work before it can be used for 3D printing. We will walk through the process from how to set up your scene and take the photos, all the way to uploading a printable file for production. If you'd like to creat your own 3D capture in class, install 123D Catch, bring a camera, and a simple object to digitize. Recommended size is larger than five inches but less than twelve. Detail is limited on small features, and your object must have some surface texture or color variation.

Finally, I'll show some examples that combine all three techniques and give a taste of the type of things that are possible with your new-found 3D skills.
