Animated sequence of dots

Hello

I would like to know if Matlab can easily do this: set a animated sequence of dots that will appear at specific location on a 2 wire-frame surface or cube. The sequence will be generated with precise sequence or randomly etc. If it is possible is there any example of such sequence or what kind of code i should use?

see the image attached

Kind Regards and thanks

There is no attached image file. Please try it again.

What exactly is a "2 wire frame surface"? Please provide more details. What have you tried so far?

The question is still not clear.

Hello Jan i have attached an extra image that should make it clearer basically the dots will appear in a timed sequence 1, 2, 3 etc and loop again.

If you have MATLAB R2014b or later, you can use animatedLine

For earlier versions you can use scatter() or plot(), updating the XData and YData properties as you go. For example,

x = []; y = [];
pointsize = 30;
h = scatter(x, y, pointsize, 'k');
for K = 1 : 20
  newx = rand(); newy = rand();
  x(end+1) = newx;
  y(end+1) = newy;
  set(h, 'XData', x, 'Ydata', y);
  drawnow();
end

But my guess is that you might be looking for Psychophysics Toolbox

thank you for tips, yes i will also be looking at Psychtoolbox-3 once i figured out how to make it work on Yosemite OS :)
