In graphics pipeline, clipping is performed after multiplication of points with perspective matrix. This is known as clip space. The input to algorithm is endpoints of line in homogeneous co-ordinates (x, y, z, w) in clip space. The outputs is clipped line (modified endpoints of line) if line is clipped. If line is removed, is_removed is set to 1. There are three cases:
1. line is unmodified (when it is inside view frustrum) (is_clipped = 0, is_removed =0)
2. line is clipped by one or more planes of view frustrum (is_clipped = 1, is_removed = 0)
3. line is outside the view frustrum (is_removed = 1)
