You may find here some examples of algebraic surfaces plotted with implicit3D.
If you click on a small image, you will have the menu of the plotter with the equation of the surfaces already loaded. Which will allow you to plot a bigger image of the surface, while playing with the parameters (colors, viewing angles, zoom, spin, etc). All 3D graphes are interactive, zoom by mouse wheel, and animation by clicking the spin checkbox.
|x2+y2-z2=0 || Quadratic cone.
||x2+y2+z2+2x y z=1 || Cubic with 4 singular points.
||x4+y4+z4+5x y z=0 || A quartic surface with 4 branches touching at the origine.
||x3+y3+z3=(x+y+z) ||a cubic surface with rotation.
||x2 y2+y2 z2+z2 x2=(x2+y2+z2-0.75)
||a quartic surface.
It plots animation by clicking the spin checkbox.
In order to plot complex function, you should convert it to complex by tocomplex(x) before plot. Use complex(x) to set variable for complex variable in real value, and Use complex(0,x) to set variable for complex variable in imag value. Get real part by re() and imag part by im(). e.g. convert log(x) to re(log(complex(x))).
Here are some particularly nice examples by plot function complex3D( ) that show real and imaginary parts of complex function including special functions on complex axes and plane.
