Homework #2 (due 03/02/04):
Familiarization with the MicroScribe 2GX digitalizer

The goal of this homework is to become familiar with the MicroScribe 2GX, the 3D digitalizer we will be using in the class.

Software and manuals

The Rhino software has been installed on Vellum the Windows machine in my lab (#3252) which is connected to the MicroScribe. Two copies will also be installed on bugles and poprocks in the junkfood lab (#3457). You might also download an evaluation version from Rhinoceros but it will only allow you to save 25 times.

I set up a Yahoo calendar so that you can reserve a machine in my lab or check if a machine is available (including Vellum, the 3D printer, and the MicroScribe) . If not reserved, machines are on a first come first served basis. If you made a reservation and you are more than 15min late, the reservation is canceled. The account name for our calendar is RPatHCIL. The password will be given in class. Please note that the MicroScribe is connected to Vellum.

Assignment

It is recommended that you work in team of two, but you might elect to work by yourself if you wish.

For this homework, you are asked to create a digital model of the mouse you studied in class using the MicroScribe. The model should include all the key features of the outside of the mouse including top and bottom surface details, buttons, and the placement of the ball. The model should be detailed enough so that the look and feel of the original mouse is accurately rendered. You do not have to create a model of the inside of the mouse nor do you need to create a model of the cord.

Please send be the resulting Rhino model before class on the day the homework is due.
