The rest of the vanishing points are elsewhere.
Actually that's my way to tell to the watchers the box is horizontal. It's horizontal lines converge on my horizon line. The brown box is oriented to be horizontal. I have sketched on both of them 2 sets of parallel lines which converge at total 4 different vanishing points. In the next image I have drawn 2 perfect rectangular boxes. And, as said, lens distortion can also spoil the effect by making the imaged lines curved.
In addition the lines of the real boat may be curved or non-parallel. If there are parallel lines in the 3D scene your photo presents they really converge towards a vanishing point in the photo (assuming the lens distortion is low enough), but it's not on the horizon because the boat is more or less tilted. The horizon is the apparent line where the assumed flat ground and the sky meet in perspective images.Įvery set of straight parallel lines have their own vanishing point and that point happens to be in the horizon only if the lines are horizontal. The sentence is true in drawing construction theory in a case where you search the vanishing point of a set of lines which are all exactly parallel and horizontal above a flat ground. I guess you wonder now why this so often repeated sentence looks wrong. You seemingly have red or heard and maybe several times that there should be a vanishing point in the horizon.
