椭球面（Ellipsoid）

http://virtualmathmuseum.org/Surface/ellipsoid/ellipsoid_lg1.html

参数方程：

with(plots): a:=2:b:=3:c:=1:

qumian:=plot3d([a*sin(phi)*cos(theta),b*sin(phi)*sin(theta),c*cos(phi)],phi=0..Pi,theta=0..2*Pi):

x_axis:=plot3d([u,0,0],u=-3..3,v=0..0.01,thickness=3):

y_axis:=plot3d([0,u,0],u=-4..4,v=0..0.01,thickness=3):

z_axis:=plot3d([0,0,u],u=-1.4..1.5,v=0..0.01,thickness=3):

xyz:=display(x_axis,y_axis,z_axis,thickness=3):

display(qumian,xyz,axes=none,grid=[54,76],lightmodel=light2);
