The torus is rotated 45 degrees counter-clockwise about the positive X axis. The coordinates of the points I and H are transformed using the following matrix:

[x'] [1   0      0   ] [x]
    [y']=[0  .7071 -.7071] [y]
    [z'] [0  .7071  .7071] [z]
See Figure (est-xrot) .

The torus is rotated 45 degrees counter-clockwise about the positive Y axis. See Figure (est-yrot) .

Figure (est-zrot): Torus Solid Edit Rotation about Z
