Curves and Surfaces Model

For my Curves and Surfaces Model, I made a desk lamp. This was inspired by the desk lamp that I have in my room. As seen in the picture, the original lamp is all gray. I added other colors to my model to make it more interesting.

The lamp that inspired this project.

The base of the lamp is a NURBS sphere that's swept from 0°-180° in order to form a half circle. The shaft of the lamp is made of two NURBS cylinders. By placing a short thick cylinder on top of a long thin one, I was able to replicate the shaft of the original lamp. The rotation mechanism for the lamp is composed of a sphere that fits into the shaft and a cylinder that extends from that sphere into the lampshade holder. The lampshade holder is a revolved surface that originated as a curve. Its shape resembles that of a funnel. The lampshade is made of two parts. The first part is half of a NURBS sphere that forms the round portion at the bottom of the lampshade. The second part is a revolved surface made from a line to form the opening of the lampshade. The light bulb is also a revolved surface that originated as a curve. The lamp shaft and other metallic parts are colored using a Blinn shader. The lampshade and base are colored using a Phong shader. The light bulb is colored using a semi-transparent Phong shader. The scene is lit using an ambient light. There is also a spotlight that points out of the lampshade at the same angle as the bulb to provide light from the lamp.
