In my 1982 version, it's on page 295. Basically, if you have 2 points P1 and P2, you can express x, y, and z as functions of t; if t=0, then (x,y,z) are the coordinates of P1; if t=1, then (x,y,z) are the coordinates of P2. As t varies from -inf to +inf you get a linear interpolation. Hope this helps... -- --------------------------------------------------------------- Maj.
