This are two 3D data files..
point = dlmread('N3d.txt');
plot3(point(:,1),point(:,2),point(:,3),'r.')
rotate3d on
point = dlmread('3d.txt');
plot3(point(:,1),point(:,2),point(:,3),'g.')
rotate3d on
I am reading this both using above code.
Now, line image created by N3d.txt have space between it if we compare it with 3d.txt file on same graph.
So, how to differentiate that space with another colour..? (I want to indicate it with another colour)

Try with this:
figure(1) ;
clf ;
hold on ;
rotate3d on ;
point = dlmread('N3d.txt');
plot3(point(:,1),point(:,2),point(:,3),'r.')
point = dlmread('3d.txt');
plot3(point(:,1),point(:,2),point(:,3),'g.')

You'll find plenty of tools for fitting lines (just look up for fit line 3d for example) and for computing euclidean distance between points/lines, but how do you define the "dimension" of a pixel in what you are trying to do?

Ok.. I have done a fitting using iterative closest point algorithm. So, they are getting overlap on each other, and giving rotational and translational parameters. overlapped image is attached here,

And maximum allowable euclidean distance is 3 between two rows.
