🔭 Vanishing Point Hunt

$ man vp-hunt

A little city photographed through a real lens. A vanishing point is where a set of parallel edges — the long sides of a box running away from you — appear to meet in the distance. This view has two of them, one for each direction the boxes face. The horizon is the same thing as the camera's eye level: the height the lens is at. Press anywhere on the sheet to drop the dashed guide there, drag it onto the hidden eye level, park a ⊕ marker on each vanishing point, then lock it in — three scenes per round. The ⊕s ride the line, because both vanishing points always sit on the eye level: slide a ⊕ sideways to move it, pull it up or down and the whole line comes along.

Rather work like you would at the easel? Press trace edges and drag along two edges of the same wall that run away from you — where your two strokes cross is that vanishing point. The line you are drawing is extended right across the sheet as you go, so you can steer it. Two strokes per point, and the eye level comes free. Undo pops the last stroke; nothing you draw costs points. Pick edges that are clearly different in angle: two that nearly agree cross somewhere meaningless, and the drill will say so rather than write a bad answer into your guess.

Keys: ← → slide the selected ⊕, ↑ ↓ raise and lower the horizon, shift for fine steps, space swaps ⊕, enter locks in.

Scoring: eye-level placement is 40%, each vanishing point 30%. Full credit inside a small bullseye, fading to zero further out. The bullseye never shrinks below a real number of pixels — so a phone is not held to a stricter standard than a desktop for the same drill — it is a little wider on a mouse or trackpad than on a pen, and scene 1 is scored gently while the words are still new.

Studio tip: pick two edges of the same wall and extend them — where they kiss is the vanishing point, and the eye level runs flat through it.
