{"version":"1.0","type":"rich","title":"equirectangular panorama to perspective","description":"This interactive WebGL visualization converts equirectangular panorama images into perspective views using Three.js. Users can upload their own panoramic image, then pan and zoom by dragging and scrolling to explore the scene as a 3D sphere. The perspective projection is adjustable through URL query parameters for field of view and output dimensions, and a button allows saving the current view as a JPEG snapshot. Built on a series of forked blocks, it demonstrates real-time spherical mapping with mouse interaction and file upload support.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f69bc5acb85692ed80a159bed0aa56b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
