Vanish

In Diagnose, a box drawing has exactly one edge rotated off its vanishing point, click the bad edge. In Build, a correct box is shown as a sandbox where you can reveal the guide rays and inspect convergence.

• Trace each family of parallel edges back toward its vanishing point.
• Click the odd edge out in Diagnose; the engine confirms or you try again.
• Toggle Show VPs to draw guide rays to the vanishing points.
• Solve quickly with few misses for a higher score; choose 1-, 2-, or 3-point perspective.

• Desktop: hover to highlight an edge, click to accuse; click play mode, point count, Daily/Practice, and Show VPs.
• Phone & tablet: tap an edge and the buttons, touch-enabled.

• Diagnose and Build, each in Daily or Practice, across 1-point, 2-point, and 3-point perspective.

• Follow each set of parallel edges in your mind's eye to its vanishing point; the one that misses is the answer.
• Turn on the VP rays in Build to internalise how correct convergence should look before you Diagnose.

Vanish teaches linear perspective and vanishing points, the foundation of representational drawing.

• Skills: linear perspective, vanishing points, representational drawing
• Best for: roughly grades 5–12 (ages 10+)
• For parents & teachers: linear perspective, made hands-on.

Finding the one edge rotated off its vanishing point, then building a correct box with the guides revealed, is linear perspective diagnosed and then constructed.

Pairing Diagnose with Build is the original structure.

Spotting the error is much easier than avoiding it, which is why both modes are needed. Perspective is a geometric construction rather than a style — every receding edge of a box must converge on the same point — so a drawing that looks almost right is usually one edge away from being provably wrong.
