• Announcements
• Programmed replication lab due
• Bezier curves
  • See also Bailey handout in shared area under this lecture
• Lab 7 out

Due at the start of class, Monday, April 5.

Please submit answers to these questions either as a hard copy (typeset or handwritten are OK) or by email to jteresco AT mtholyoke.edu by the start of class. We will discuss these questions at the start of class, so no late submissions are accepted. Using the "scaffolding" construction we saw in class, show the points on the Bezier curve defined by the points A, B, C, and D as shown below, at times t=0.25, t=0.5, and t=0.75.

t=0.25	t=0.5	t=0.75

• Some Java applets at Imperial College in London that help construct Bezier curves, including ones made of multiple segments:
