Simplest way of plotting a 3d graph in Maple?

Question

Say I have a velocity field given by u = (y^3, 0, 0). What is the simplest way of plotting the vorticity of this field w = (3y^2, 0, 0) in Maple over the domain x in [-3, 3], y in [-3, 3]?

Answer 1

You can use the plots:-fieldplot3d command for a 3D plot (or the plots:-fieldplot command for a 2D plot).

There are several options which affect the look and feel, sizing and number of the arrows, etc.

For example,

plots:-fieldplot3d([0,0,-3*y^2], x=-3..3, y=-3..3, z=-10..10,
                   grid=[4,8,2], arrows=`3-D`,
                   fieldstrength=log[1.2], orientation=[43,66,0]);

You can use the plots:-display command to combine several such plots, where each has its own color say.
