I have been searching on Google about it, and I found that given a sample, 4 points, per example, I could find a function and use integral on it.
I am sorry if it sounds silly, I am very dummy in mathematics. How could I find the area of this curve?
Clarification
I want to know the length of the trajectory of the center of an object moving in 3-dimensional space.
In the comments they helped. I've found the solution: √((x2−x1)^2+(y2−y1)^2+(z2−z1)^2)
It was just a simple case of of getting the length of 3d diagonals.
Thank you very much for the help.
