Given in 3D Ellipsoid semi major axis a=5 (along axis) and semi minor axis b =4 ,c=3 (along y and z axis) . How can we find the distance D between two focal points (P0 and P2) ? Also how to find the distance from focal point P0 to P1 ? Also will the distance from P0 to P1+ P1 to P2 be equal to 2a like in ellipse ?
Hi Muhammad,
You give 3 different values for the semi-major axes so there are many different focal points, one pair for each cut plane through the center of the ellipsoid.
Nan Chu Sir its one ellipsoid with semi major axis a=5 , semi minor axis b=4 and c=3 . Would you kindly give an example to calculate the distance from P0 to P1 ? where u=azimuth angle (along z axis) and v=elevation angle (along y axis).
Jacques B Sombrin Sir i have corrected the question. Its only one ellipsoid with three axis (x,y,z) where x (2a=x) is semi major axis and y (2b=y) and z (2c=z) are semi minor axis. Where u=azimuth angle (along z axis) and v=elevation angle (along y axis) . Keeping in view such conditions. how do we calculate the distance from P0 to P1. Also is there any way we can compute the distance between two foci P0 and P2, while keeping the a, b, and c as constant values such as (5, 4, 3 ) respectively .
