MATLAB-3D动画图

Question

I have a matrix with 4 variables. I want to plot the results as a 3D surface animation, having 3 of the variables as x,y and z and the 4th variable as time (t).

I imagine the code to be something like:

figure(1)
plot4d(Results(:,1), Results(:,2), Results(:,6), Results(:,3))

Here is some sample data:

    X         Y         t                            Z

The goal is to produce a 3D surface plot that varies with time, so that it looks like someone is waving a blanket ;)

Answer 1

If what you plot is a line, then you could just display it frame by frame, pausing between them according to the time stamp (assumed to be in seconds):

 x = Results(:,1);
 y = Results(:,2);
 z = Results(:,3);
 t = Results(:,4);
dt = [diff(t);eps]; 

h = axes('Parent', figure());
hold(h, 'off');

for k = 1:numel(t)
        plot3(h, x(1:k), y(1:k), z(1:k), '-*k');
        pause(dt(k));
end;
