How to compute the distance between 3d points in a fast way
1 I have a 3d point x y z in a txt file I want to calculate the 3d distance between each point and all the other points in the point and save the number of points having distance less than a threshold I have done it in python in the shown code but it takes too much time I was asking for a faster one than the one I got

How to calculate distance between two points in 3D Ask ion Asked 5 years 3 months ago Modified 3 years 10 months ago Viewed 4k times 1 I have two lists Each list has three lines The coordinate system is x y z from up to down for each list I tried to use array but it didn t work Here are my codes Python How to calculate distance between two points in 3D Stack . Also contained in this module are functions for computing the number of observations in a distance matrix Distance functions between two numeric vectors u and v Computing distances over a large collection of vectors is inefficient for these functions Use pdist for this purpose To find the closest points along the lines you recognize that the line connecting the closest points has direction vector n e1 e2 20 11 26 If the two direction vectors e1 and e2 are parallel not in this specific case this method cannot be applied because the cross product is zero
