Tutorial 51 - Three Point Perspective
Added 2016-02-21 09:09:16 +0000 UTCWe have two vanishing points which sit along the horizon line, as in two point perspective. Though, unlike two point perspective, where all vertical lines are parallel, in three point all vertical lines converge together at the third point. The third point is placed either above or below the horizon. If placed above then we must be looking up from a worms-eye point of view. If placed below then we have an aerial view.
The three vanishing points create a triangle which should be considered a distortion boundary. Anything drawn outside of the triangle will look very strange. It's best to create a page/ canvas boundary within the triangle, to avoid distortion. The smaller the page boundary the more zoomed-in we are to our scene. This is similar in effect to a telescopic lens on a camera.
