Box Perspective Helper

Box Perspective Helper is a minimal drawing reference tool for artists practicing 3D perspective.

It visualizes a simple box and shows the relative lengths of its edges compared to a default front-facing cube, helping you understand how dimensions change in perspective. Use it alongside your sketchbook or tablet to improve proportion, depth, and spatial reasoning.

Features

• Simple 3D box visualization

• Line length comparison against a default front-facing cube

• Orthographic and perspective view modes

• Adjustable field of view (FOV)

• Box rotation for studying different angles and depth relationships

This tool is intended as a learning aid and reference, not a replacement for drawing fundamentals.

Note: This tool was made with the help of Claude AI as a coding and brainstorming assistant.
