Transformation for parallel projection

Parallel projections is also termed as Orthographic projection, are projections into one of the coordinate planes as x = 0, y = 0 or z = 0. The ordinary transformation for parallel or orthographic projection into the xy-plane that is z=0 plane as:

Ppar,z =  x ' = x

y ' = y

z ' = 0

In matrix form it as:

Hence, if P(x,y,z) be any object point in space, then projected point P'(x'y'z') can be acquired as:
