A tetrahedron is to be moved along a trajectory such that at the end of the trajectory (t=1)
it is rotated 45 deg. about the vector [1,1,1] (positive
rotation) and the centroid of the
tetrahedron is translated to [x,y,z]=[2.525, 1.675, 1.575].
Calculate the transformation
matrix at t=.50 using linear interpolation for the translational
and rotational part of the
transformation matrix. (Hint: for the rotational part interpolate
the quaternion
representation of the rotational part).
A tetrahedron originally has coordinates at t=0:
P1=(1.5,0.20,1.5)
P2=(2,0,0)
P3=(1,0,0)
P4=(1.6,2.5,0.8)
Centroid=(1.525,0.675,0.575)
