- 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 |

- A Java applet at Brown that can be useful for defining Bezier curves:
- Some Java applets at Imperial College in London that help
construct Bezier curves, including ones made of multiple segments:
