Hi Pooja,
From my understnading you want to rotate a 3d scatter plot programatically. For surface, line plot MATLAB have rotate which can rotate a figure about a particular direction and given degrees. But that doesn't work for the 3dScatter plot . But there is work around that :
1)Draw a 3d line plot of the corresponding scatter plot
2)Rotate that 3d line plot using the rotate function.
3)get the data from the line plot and draw the corresponding 3dScatterplot .
For ex#
figure
[X,Y,Z] = sphere(16);
x = [0.5*X(:); 0.75*X(:); X(:)];
y = [0.0*Y(:); 0.0*Y(:); Y(:)];
z = [0.0*Z(:); 0.0*Z(:); Z(:)];
scatter3(x,y,z);
This will plot this scatter plot :
Step 1:
when we draw the line plot of this scatter plot :
figure(2)
p = plot3(x,y,z);
Step 2:
Now we rotate this around z-axis by 25 degrees as:
direction = [0 0 1];
rotate(p,direction,25);
so we have :
Step 3:
Now we get the data from the rotated line plot and plot a scatter plot as follow:
x =p.XData;
y = p.YData;
z = p.ZData;
figure(2);
scatter3(x,y,z)
so we have :
To do this in continuous loop :
figure
[X,Y,Z] = sphere(16);
x = [0.5*X(:); 0.75*X(:); X(:)];
y = [0.0*Y(:); 0.0*Y(:); Y(:)];
z = [0.0*Z(:); 0.0*Z(:); Z(:)];
scatter3(x,y,z);
p = plot3(x,y,z);
for i=1:10
direction = [0 0 1];
rotate(p,direction,25);
x =p.XData;
y = p.YData;
z = p.ZData;
figure(2);
scatter3(x,y,z);
pause(2);
end
Hope this helps
Thanks
