 # panellum_generator
 
-Configuration generator for Panellum Panorama Viewer.
+Configuration generator for Panellum Panorama Viewer.
 https://pannellum.org/
 
 ## Usage
 
-python panoconfig.py input.txt -o index.htm
+python panoconfig.py input.txt -o pannellum/index.htm
 
 put index.htm in panellum folder together with images inside images/ folder.
 
 ## input config file format
-x,y,z,id,filename,angleoffset
+FromFile,ToFile,Pitch,Yaw,TargetYaw|i
 
-xyz have to be a consistent unit
-angleoffset is positive if center of image is rotated ccw
+## overlay Pitch and Yaw
+run overlaylatLong.sh with .jpg files in same directory. 
+This will create an "overlay" directory with the fotos and a lat long overlay.
 
+## Workflow
+Add .jpg equirectengular 360 photos in a directory with overlayLatLong.sh .
+Run overlayLatLong.sh
+create a file (for example input.txt)
+Add clickable hotspots in every line
+Example: from kitchen.jpg to livingroom.jpg at pitch=0 and yaw=-30 (coordinats in from picture).
+kitchen,livingroom,0,-30,i
+(i for autocalculate yaw viewpoint in target photo)
+
+Every image in the "to" field has to exist at least once as "from".
+
+Download pannellum and put pannellum folder in directory next to the python file.
+Run "python panoconfig.py input.txt -o pannellum/index.htm" to create index.htm with config in it.
+Run python -m http.server in pannellum folder.
+Navigate to http://localhost:8000
