Frequently Asked Questions
What image aspect ratio and format is required for this 360 viewer?
The viewer expects standard equirectangular spherical panoramas formatted in a 2:1 aspect ratio (e.g., 2048×1024, 4096×2048, 6000×3000, or 8192×4096 pixels) saved as standard JPG, PNG, or WebP files.
Are my uploaded 360 panoramas uploaded or stored on any server?
No. Atlyxen Tools operates 100% client-side. Your images are parsed directly into your local GPU hardware via WebGL and HTML5 File APIs. No data ever leaves your device, guaranteeing full compliance with client NDAs and confidential commercial projects.
How do I export 360 equirectangular panoramas from 3ds Max and V-Ray / Corona?
In V-Ray, set your camera type to "Spherical" with an Override FOV of 360 degrees. In Corona Renderer, select the CoronaCamera, navigate to Camera Projection, and change Type to "Spherical (Equirectangular)" with a 2:1 image resolution in Render Setup.
How do I export 360 panoramas from Blender Cycles or Eevee?
In Blender, select your Camera, navigate to Camera Properties, set the Type to "Panoramic", and choose "Equirectangular" for Panorama Type. Set your render resolution dimensions to a 2:1 ratio (e.g. 4096 × 2048).
Can I view panoramas on iPhone, iPad, Android, and VR headsets?
Yes! On mobile devices, you can swipe to look around or activate the Gyroscope button to turn your phone into a magic window. In VR headsets like Meta Quest or Apple Vision Pro, launch the viewer in browser fullscreen mode for an immersive room-scale experience.
What is Little Planet mode?
Little Planet (stereographic projection) mathematically curves the 360 panoramic horizon inward into a spherical planetoid, producing dramatic miniature world visuals popular in architectural presentations and social media.
How do I embed this 360 panorama player into Webflow, WordPress, or my website?
Click the "Embed" button in the top action bar to open our embed generator. Copy the responsive iframe snippet and paste it into any HTML embed block in Webflow, WordPress, Squarespace, or custom code.
What is the maximum resolution supported by the WebGL viewer?
The viewer dynamically queries your graphics card MAX_TEXTURE_SIZE. Modern desktop GPUs support up to 16384×16384 (16K), while mobile devices comfortably render 4096×2048 (4K) and 8192×4096 (8K) equirectangular textures without frame drops.
