pan - initial pan angle (-180...180, default 0) fov - initial horizontal field of view (12...165, default 70) auto - autorotation angle (-360...360, default 0) pan angle is incremented by that amount for each frame. Specify degrees, fractional values allowed. antialias - Set this option to 'true' to turn on the Antialiasing feature. A series of scaled source images is created. Antialiasing is supported for equirectangular panoramas, QTVR panoramas (cylinders, cubes) and PTZoom images. oversampling - This floating point parameter is used with the antialias option above. It determines the maximum ratio of source resolution (pixel/degree) to screen resolution (pixel/degree). The default value is 1.5. Larger values cause more aliasing, while smaller values soften the view. cache - Set to 'false' if you want to disable PTViewer's internal RAM image cache (default: true). This may be required for very large tours which don't fit into RAM. Wait Image - URL of image to be displayed while Virtual Tour is loading.
