About

DioramaMapMaker

Read full description

A new landscape starts with a theme. Create and explore terrain on iPhone and iPad, then take your favorite result into your own creative workflow. CHOOSE A WORLD Start with Forest Valley, Coastal Islands or Wind-shaped Desert. Generate another variation in one step, then adjust vegetation density, terrain relief and material appearance. Advanced controls give you access to presets, seeds and terrain settings. KEEP WHAT YOU LIKE Save complete versions in My Scenes on your device. Add names and notes, make copies, compare results and return to a favorite. Clear apply and discard actions help you explore changes while keeping the completed scene. TAKE YOUR SCENE FURTHER Share a .diorama scene package, a USDZ model or a USDA archive with its PNG texture. Models use meters and preserve the exported scene's scale. USDZ and USDA are static models; the App's wind, flowing-water animation, sound and controls do not automatically carry into other tools.
