Description

A web-based WebGL Panorama Editor/Viewer. Some older PCs and browsers might not be able to handle the graphics.

Stitched results WebGL Editor/Viewer snapshot

Sample Route

Sample route in WebGL Pano Editor/Viewer.

Source Code

http://elphel.git.sourceforge.net/git/gitweb.cgi?p=elphel/webgl_panorama_editor;a=summary

or in a terminal window (Linux)

git clone git://elphel.git.sourceforge.net/gitroot/elphel/webgl_panorama_editor

Note: There might be problems with the Google Maps API key. It's personal and needs to be regenerated.

Requirements

• A stitched panorama of 14268x7135 in size in JPEG format splitted into 8 square 3568x3568 tiles with a 1 pixel overlapping.

Tiles

• A KML route file created manually or extracted from the source files.

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">

</kml>

• Note 1:
  • If the panorama name in KML is sample.jpeg then the tile names will be named by adding indices starting from the top-left tile and finishing with the bottom-right tile from left to right:

Name in KML:
 sample.jpeg
Tile names:
 sample_1_8.jpeg (top-left)
 sample_2_8.jpeg
 sample_3_8.jpeg
 sample_4_8.jpeg (top-right)
 sample_5_8.jpeg (bottom-left)
 sample_6_8.jpeg
 sample_7_8.jpeg
 sample_8_8.jpeg (bottom-right)

sample.jpeg

• Note 2:
  • HREF-tag in the KML file must have an absolute or relative from the WebGL Editor's index.html HTTP-path. Images and the Editor files must be stored on the same web server - WebGL fails to load images from external servers due to the security reasons.

Links

• Google KML reference
