    The desire is to use the mouse cursor to click on the earth and to find the surface point under the mouse cursor. Once the surface point is found it should be converted from x,y,z to latitude, longitude so that it can be fed into the uber h3 geodisc/hexagon library. Then the library will return a H3 index which can be turned into hexagon vertices which describe a polygon in which this latitude longitude point lies. Then it's also possible to "increase the resolution" of the H3 index so that the hexagon...

    Trying to convert from X,Y,Z to Lat, Long and then later back from Lat,Long to X,Y,Z. A cube set to these coordinates X,Y,Z and the camera targer object the cube. Somewhat strange camera movement but not to bad... Strangely enough seems to be slightly off center from H3 library, not sure what the cause is, I wonder if the ray tracing is accurate, I would assume so, maybe that assumption is the mother of all fok ups, but playing with the R value does change the center a bit, better but still strange...

    SceneScale seems to work very well, what is this ? :)

    In this video you can see me playing around with GLScene and GLCamera and Uber H3, the code using GLSphere ray tracing. Near the end of the video you can see me playing with camera settings to try and zoom in as far as possible, but at some point the sphere gets cut away and such. Is there anything that can be done about this ? What would be the best setting to be able to zoom in as much as possible ? Maybe the settings for camera should be changed "on the fly" as the camera zooms in further and...

    My best guess is, adding triangles on BeforeRender does not call the back face culling code later... so it won't work in there... I would have to move code elsewhere... Complex library with all kinds of catchas... hmmm...
