Please let me know the formula for the coordinate of the midpoint of 2 points in spherical coordinate system . If possible , I want the answer includes the exact formula as , midpoint = point1 + ( point2 - point1 ) / 2 .
Thank you very much
Thank you very much for the answer. Is it necessary to compute the Cartesian coordinate of the midpoint ? No means to compute directly the spherical coordinate of the midpoint ?
Thank you for the second answer . I am happy to know that I must use Cartesian coordinate system for the purpose .
Please someone let me know how to mark the answer as my accepted answer. There is no button for the purpose on my page .
