3D Plots and vector fields [duplicate]

I'm a beginner. How I make a 3D Plot from zero? (like a graphics with the potencial of the electric field). I have to make vector fields too. (vectors of the electric field). I search at internet but ...

Plotting implicitly-defined space curves

It is known that space curves can either be defined parametrically, \begin{align*}x&=f(t)\\y&=g(t)\\z&=h(t)\end{align*} or as the intersection of two surfaces, \begin{align*}F(x,y,...

Plotting a set of trajectories (not a vector field) in 3D

Consider a set of trajectories in 3D space, that possibly converge. By visualizing trajectories as arrows the result will look crowded as each arrowhead will be placed where the attractor is. In 2D, ...

Visualizing vector-spherical waves

This is a follow-up question to this one on visualizing vector-spherical harmonics. This time, I would like to visualize the vector spherical waves (including the radial dependence). The functions ...

StreamPlot in 3 Dimensions

I would like to plot the vector equation $\left( {\begin{array}{*{20}{c}} {\frac{{ - a + \sqrt {{a^2} + 4bc} }}{c}}\\ {\frac{{ - a - \sqrt {{a^2} + 4bc} }}{c}}\\ 1 \end{array}} \right)$ as a stream ...
I have a dataset of $\textbf{B} = {B_x, B_y, B_z}$. (Quite a big dataset :78*100*150) I want to plot magnetic field lines. If I was working with an analytical function, the magnetic field line ...
