I am given 4 points, each is a corner of a plane to a box.
p1=[0;0] p2=[sqrt(3/4);-1/2] p3=[sqrt(3/4);1/2] p4=[0;1]
I want to rotate the plane counterclockwise with 120- and240 degree. so that i get a box of some sort.
——-
what i try to do is to make a matrix of the first plane, give the rows x and y varribles and plot them in.
>> fill(x1,y1,'r')
which works fine.
now i want to rotate it with 120 degree. so i make a rotation matrix
theta= 120
R=[cos(theta) -sin(theta); sin(theta) cos(theta)]
I multiply it with the previously matrix, and put new varriables on the new matrix, like x2 and y2
fill(x1,y1,'r',x2,y2,'g')
for some reason it does not obbey my command :S
any tips and trick?
