Just a reminder that there will be a midterm review on November 3. This means that all assignments with due dates up to and including 11/3 are due that day to your FTP directory by midnight. I will not accept assignments from the first half of the semester after that date. I do this so that everyone can get caught up and prepared to move on to the second half of the course.

The Assignments section of the website clearly describes all homework assignments and due dates. This is a list of folders I should see in the Assignments folder of your FTP directory:

• Exercise 1
• Modeling Exercises 2
  
• Modeling Exercises 3
• Revolved Vessel (was originally called "Revolve Practice")
• Modeling Exercises 4
• Table Set
• Rendering Fundamentals
• Writing Instrument
• Peruvian Vessel
• Light Design
• Lofted Vessel

Here are a few rendering set backdrops for use in today's lesson. You may want to use these to create your own rendering set assemblies. Notice that these models use surface features, which we have not covered yet. However, they can be placed into an assembly just like a normal solid body part.

Ancient Peruvian Stirrup-Spout Vessel

This is a typical ceramic vessel from the Andes region of South America, ca. 12th-5th century BC. The handle/spout design is called a "stirrup spout" due to its similarity to a horseback rider's stirrups. This model provides yet more opportunity to practice revolves and sweeps. This particular piece is part of the collection at the Metropolitan Museum of Art. You can see a picture of it here. For this exercise we're only interested in the basic shape, not the surface details.

Since the vessel is hollow with an opening at the top, the best approach will be to model the whole thing as a single solid body and then use the Shell feature to hollow it out. I used a wall thickness of 3mm, which seemed to work well. On the Shell feature screen, you can select the top face under "Faces to Remove" to keep the top open. Alternatively, you can use Extruded Cut or Revolved Cut to make an opening after the Shell. Note that the entire interior of the vessel should be connected, such that liquid in the bottom can be poured out the top opening; see the section view in the images above.

I'm not providing any drawings for this one, just an eDrawings file. I highly recommend saving the image on the website above and using it as a Sketch Picture guide for the Front plane of your model. The artifact is approximately 8.5 inches high, so scale the picture accordingly.

Finally, when modeling this myself based on the website picture, I realized that the stirrup (loop) part of the handle/spout most likely has an oval (elliptical) profile, rather than circular. If you try it with a circular profile, you'll probably find that the top spout is too big to fit on the handle part. You can see what I mean in the eDrawings file. 

Two of the video tutorials cover the Shell feature, and may be helpful when working on this model.

Optional but recommended: Try your hand at setting up a rendering set assembly using the techniques presented in class on 10/20. Use one of the sample backdrops provided in class, set up some lights, and place the vessel model in the set. See if you can get a nice rendering with soft shadows. We will be working much more on our rendering sets over the coming weeks, but this will get you started.

These are SolidWorks files for the two demo lamps that we did in class on 10/13. It may be helpful to step through these models feature by feature to reinforce what you learned.
