I am given the $3$-D coordinates of two triangles. For example:

  • for $\triangle ABC$, the coordinates are: $A=(0, 0, 0)$, $B= (3.37576, 0, 0)$, $C=(5.14131, -2.47202, 0)$

and

  • for $\triangle DEF$ the coordinates are: $D=(0, 0, 0)$, $E(3.73345, 0, 0)$, $F=(7.06825, -3.44094, 0)$.

How to calculate the transformation matrix between two triangles?

Any help will be largely appreciated!

    Do you see that both triangles lie in the x-y coordinate plane? (i.e., both triangles are, essentially, in 2-dimensions), Each with a vertex at the origin (A, D), and each with one side lying along the x-axis, overlapping (side DE a bit longer than side AB?), and each lying in the same quadrant?2011-05-31
