For the line crossing from points P0(x0,y0,z0) and P1(x1,y1,z1) and in the direction of vector P0P1 we know that :
So the line equation will be :
So how we can obtain the coordinates of the middle point M(x,y,z) on the P0P1 line with equal distance from P0 and P1?
(Can you please let me know how can I write mathematics formula here? For example, writing them in Microsoft Word 2007 and then copy-paste here?)
