Details

The square matrix above is the transformation matrix used. Below it are the coordinates of the initial cube and those of the transformed cube shown in this image. (Sorting by the list on the right makes it easier to find them in the image.) In a matrix multiplication the matrix is multiplied from the left, and the coordinates are column vectors.


The tables on the right show the same coordinates, but formatted to be read as those of the orthographic projections. Those marked with a darker frame are the ones shown in the 3D image. (Also their axes are in alphabetic order, which makes them more intuitive to read.)

(−2, −1, −2) (0, 1, 0) (0, −1, −2) (2, 1, 0) (−2, −1, 0) (0, 1, 2) (0, −1, 0) (2, 1, 2)
