Tues Jun 24
Go over LAMP Ch 4 Module 3 Computer Graphics.
Then work on Problems 1 and 3.
Hints on Problem 1:
Look at Section 1 example 1c, but use rotation by -Pi/6.
We also need to shrink the triangle as it goes around, so, instead of
letting M equal U.R.T, you need to add in a dilation matrix A somewhere
(using, for example, the command
A:=Diagmat([1/2,1/2,1]); and
M:= the product of the 4 matrixes A, U, R, and T in some order that makes
sense, and
Movie(M,triangle,frames=18); but adjusting the dilation so that
it matches the problem.)
Hints on Problem 3:
Try a rotation matrix composed with a translation matrix.
