6. To find the closest distance, l, of the point p from L we recognize that the projection of the vector p − P1 onto PL allows us to find the point, q, on L which is closest to p. 0) { p is closer to the line outside of the segment from P1 to P2 } 20 2. 6: Closest distance of a point from a line segment. , between the points P1 , P2 . This algorithm is useful for a 3D application program where it is necessary to interactively pick a line by touching it, or pointing to it on a display with a user input device such as a mouse.

4: Specifying a line. The parameter µ takes values in the range −∞ < µ < ∞. Note that when µ = 0 then p = P0 . 0. Using two points to express an equation for the line is useful when we need to consider a finite segment of a line. ) Thus if we need to consider a line segment we can assign P0 and P1 to the segment end points with the consequence that any point on the line p will only be part of the segment if its value for µ in the equation above lies in the interval [0, 1]. 5 The plane A plane is completely specified by giving a point on the plane P0 , and the direction n ˆ perpendicular to the plane.

Dx , dy and dz are the components of vector d. where:  0 [Tc ] =  uz −uy −uz 0 ux  uy −ux  0 u2x  [Tt ] = uy ux uz ux ux uy u2y uz uy  ux uz uy uz  u2z is the cross product matrix and:  is the tensor product. This neat expression is a matrix form of Rodrigues’ rotation formulae. 12. 15: Surface local coordinates: (a) A point on an object with position P in the global (world) frame of reference has a surface local frame of reference, (b) in a two-dimensional section. (c) The relative orientations of the local and global frames of reference.
