2D Section of 3D coordinates
9 views (last 30 days)
Hello, I have a 3D plot and the x y z coordinates of corresponding vertices as vectors n:1, m:1 and p:1. There is no function f(x,y,z). From theses vertices I want to get a 2D profile of an arbitrary sectionplane. It's possible that the points are not part of the plane. Is there a function for this problem?

I think you can do it all just by using coordinate transformations. Transform your x,y,z coordinates so that the origin and the x,y axes lie in the plane of interest. Then throw away all (x,y,z) data whose distance from the plane (as measured by the new z coordinates) are too large in magnitude. Then, make a 2D plot of the (x,y) in the data that remain.
