coordinates of a 3D line
Posted:

Hi,
I'm starting with 3D and I want to plot a line in 3D which start in one point P1 and finishes in another P2, and obtain all the coordinates points of the line with a resolution R. Could I do something similar to the following: I don?t know the value for t: P1=[1 5 2]; P2=[0 0 0] resol = 0.1; x0 = P1(1); y0 = P1(2); z0 = P1(3); t=1:resol:1 dx = P2(:,1)P1(:,1) dy = P2(:,2)P1(:,2) dz = P2(:,3)P1(:,3)
x = x0 + t*dx y = y0 + t*dy z = z0 + t*dz
plot3(x,y,z,'b')
Thanks very much
