Hi Bharath,
If you want to get the 3D coordinates of the point where the mouse is clicked, you can make use of the CurrentPoint property of the current axes object to get the 3D coordinates of the current location of the mouse as follows:
>> get(gca, 'CurrentPoint')
For more information about the property, kindly have a look at the 'CurrentPoint' documentation here.
Hope this helps.
Regards,
Alok
