Use the following functions defined in the GraphicsFunctions.mthZG4ZTI utility file to draw grid lines and points in a 3D-plot window:


GRID_LINES(a, b, s, o) simplifies to a matrix that plots in a 3D-plot window as three sets of grid lines parallel to the Oxy, Oxz and Oyz planes.  Each coordinate moves from a to b in steps of size s about the point o.  s defaults to 1, and o defaults to the origin [0, 0, 0].  For example, with the Options > Approximate Before Plotting optionEVZ132 turned on,

GRID_LINES(-5, 5)

plots grid lines over the Oxy, Oxz and Oyz planes of the 3D-plot window.  As another example,

GRID_LINES(-5, 5, 1, [-5, -5, -5])

plots grid lines over the back walls and floor of the 3D-plot window.


GRID_POINTS(a, b, s, o) simplifies to a matrix that plots in a 3D-plot window as three sets of grid points parallel to the Oxy, Oxz and Oyz planes.  Each coordinate moves from a to b in steps of size s about the point o.  s defaults to 1, and o defaults to the origin [0, 0, 0].  For example, with the Options > Approximate Before Plotting optionEVZ132 turned on,

GRID_POINTS(0, 5)

plots grid points over the first octant of the 3D-plot window.
