WebVanishing points One of the more interesting and familiar phenomena in perspective geometry is that parallel lines in the 3D world typically project to non-parallel lines in the image and in particular these projected lines intersect at a image point – called the vanishing point. Parallel lines are quite common in man made environments. WebThe perspective projection of any set of parallel lines that are not parallel to the projection plane converge to a vanishing point. The vanishing point for any set of lines that are parallel to one of the three principle axes of an object is referred to as a principle vanishing point or axis vanishing point.Explain Three-Point Perspective Projection.
