  In the last post I converted an 195 year old image from Carl August Richter into an version that can be viewed with an VR headset. Now I found an older version of this image. I cleaned it up and changed the colours and than made the same then in the last tutorial. And now we are able to view this more then 195 year old image in 3D wireframe style with a VR headset. https://photos.app.goo.gl/jGhWqyXwtNXPZeNo9

I found this image from Carl August Richter in an article about Dresden in Wikipedia. I think I found one of the oldest "little planet". I created images like this already myself some times: Little City Planet , Elbe Sandstone Mountains Now I had the idea to do it reverse and create an 360° panorama that can be viewed with an VR headset. (I use the Google Daydream.)  This is the original image, that you can download from Wikipedia: https://de.wikipedia.org/wiki/Frauenkirche_(Dresden)#/media/File:Dresden_Umsicht_Frauenkirche_1824.jpg The first step is to centre the image. I used two guides in Gimp,  Image->Guides->New Guides (by percent) and then used the move tool to place the picture. After that I used the crop tool to to create a perfect square image. To unroll the image I used the "Little Planet" plugin with an inverse transformation to create the classic panorama:  Filters->Map->Little Planet
