Added the computational difference script, not sure what is needed for the equation as I think a pseudo-code with a for loop for every point would work.
For the equation, there was a mistake. It needs to be
\begin{aligned}
\mat{p}' = \mat{R}_2 (\mat{R}_1 \mat{p} + \mat{t}_1 ) + \mat{t}_2
\textcomma
\end{aligned}
With a lowercase p
. Check the text to make sure it fit the change of equation.
We cannot sum a matrix with a vector: \mat{P} + \mat{t}
.
Fixed in next commit.
In
lessons/transformations_2d/3-lesson_rigid.ipynb
add a script that compute the time of moving a point cloud using matrix mult. vs for loop.Aslo, in Section "2. Combining basic transformations", review that question:
as it only work for a point, not for matrices.
