symmetry about the x-axis
Like all linear transformations that command is in 2 modes:
direct and matrix.
symx image
symx(x)image(id)inv
X symmetrizes image id
relative to point (x,0) normalized (center (0.5,0) default).
symx obj
symx(x,y,z)obj(id)
X symmetrizes objet obj id
relative to the plane parallel to the yz plane through (x, y, z) (default origin).
symx var
symx(x,y,z)var("x")
X symmetrizes variable x
relative to the plane parallel to the yz plane through (x, y, z) (default origin).
