I have this text file,
http://speedy.sh/sANpC/New3d.txt
And script for it is,
fileID = fopen('New3d.txt');
C = textscan(fileID, '%f %f %f');
fclose(fileID);
x=cell2mat(C(:,1));
y=cell2mat(C(:,2));
z=cell2mat(C(:,3));
patch(x,y,z,'R')
view(3)
axis equal off tight vis3d; camzoom(1.2)
colormap(spring)
rotate3d on
I have written this script to create 3D..
But this script connects all the points in image, where as i only want only to put the poins, so, how to do it..?

Instead of using patch(), use
scatter3(x,y,z)

Yes, i already tried it. But, it is also showing so big blue circle dots. As my text file points are so dense, so i want only point which looks like just a dot..
