How to get ath atv from the coordinates of a point x y?

Hello everyone!

There is a point [map] - image. distorted="true"
There is a conditional point on the image with known coordinates x y.

screentosphere(x,y,h,v); - this option did not work because the coordinate is relative to the hotspot binding

How to get ath atv from the coordinates of the point x y ?

Check the documentation ?

Hi, I tried, but it's not it.
even if I assign a layer to a hotspot, I won't get its spherical coordinates.
The original meaning is this:
There is an image with plot markings.
There are plot coordinates on this image (x y)
I overlay the image with plots on a place in the panorama.
Then I want to automatically create polygons from the known plot coordinates (x y).
But for this I need to get spherical coordinates of points from (x y)

or.. you use a canvas and paint on it... but that is only possible w javascript

Yes, the picture with the plots is a hotspot.
I know the coordinates of the plots, how can I convert them to spherical coordinates?
If I get spherical coordinates, I can create polygonal hotspots.
Then the picture with the plots will be deleted, it is used as a template.
I can get the coordinates using tx tz, but then the hotspot with the plots must coincide with these axes and not have slopes, this is inconvenient

Hi,

Isn't it an option to lower the alpha on the hotspot a bit, set enabled false and draw the polygones?

Or do you really want to calculate?

Hi!
That's what I do It's a long process, I want to automate it, I already automated it, but my method has its drawbacks.
I want to use an array of coordinates to automatically create polygons, so as not to draw them manually. When there are more than 200 areas and on several panoramas, this is a long process.

ok, thats not a layer, its a distorted / rotated hotspot placed by ath/atv.

layertoscreen is most likely not working in this case.

mathematically it would be possible to get ath/atv as 3d coordinates (spheretospace)

then add the position vector, then use spacetosphere to get the target points ath/atv

problem is how to get the position vector ;)

its your picture space coordinates, but rotated by rx/ry/rz ...

to combine the image with the ground, you often have to rotate the hotspot, scale and rotate it along all axes. Probably, you need to calculate the position of each point in 3D space taking into account the scale tx tz rx ry rz of the hotspot

you'd need a get_picture_coords_from_hotspot_to_space(hotspot, x, y) function :)

tricky ... but possible ... (but don't ask me) :D

If there was such a function in the arsenal of krpano, it would be useful

Thanks to everyone for the ideas and tips. Brain strain + artificial intelligence helped me solve the problem

how are you doing it now ?

Hi!
1. I set up a hotspot (a map with areas) in 3D coordinates
2. I calculate x y taking into account the scale factor (pixelwidth/imagewidth)
3. I get 3D coordinates of the point taking into account rotations along the axes rx ry rz from x y locally on the hotspot (the code in js was written by ai Grok)
4. I set the offset for the point by tx ty tz as for the hotspot and get 3D coordinates of the point
5. I get ath atv spacetosphere(tx,ty,tz);
It was possible to leave 3D coordinates but not all polygons are visible
I do this for each point in the coordinate array and create polygonal hotspots
