Ocuvane is an offline spatial visibility studio for designing fictional environments and exploring what can—or cannot—be seen. BUILD VISIBILITY STUDIES Place observers and targets, define barriers and openings, and examine their spatial relationships on an interactive canvas. EXPLORE SIGHTLINES Trace direct sightlines and identify how environmental geometry affects visibility between each observer and target. ANALYZE THE ENVIRONMENT Generate visibility fields, exposure studies, coverage views, and blind-region analyses from your project geometry. COMPARE REVISIONS Save project versions and review how edits change sightlines, visibility, and obstruction relationships. CREATE STUDY ATLASES Assemble visual study pages and export polished atlases for sharing or reference. PRIVATE AND OFFLINE Your authored projects remain on your device. Ocuvane does not require an account, analytics, advertising, or a remote content connection for its core studio features. Ocuvane is intended for fictional, conceptual, and creative spatial studies. It is not a substitute for professional architectural, engineering, safety, or regulatory analysis.
