Passing Current Scene hlootat, vlookat values to next scene

Hi
Can someone help me with this:
When the viewer clicks the hotspot to move to the next scene, I wish to capture the hlookat, vlookat values of the current scene and pass it on to the linkedscene so that I can align the next scene to the current view.

Why not simply use KEEPVIEW during loadpano call?

Thanks Alexey,
But in some cases, I noticed that I might have to off-set the hlookat value. That is adding or reducing the hlookat to match the next scene.

Hi,

you could:

use KEEPVIEW and then directly after the loadscene() call add the offset to the current view.hlookat:
Quellcode

1 2

loadscene(..., null, MERGE|KEEPVIEW, ...); add(view.hlookat, YOUR_OFFSET);

save the current lookat values, load the scene, load the previously stored values and set them with an offset:

	Quellcode
1 2 3 4	copy(cur_hlookat, view.hlookat); copy(cur_vlookat, view.vlookat); loadscene(...); lookat(calc(cur_hlookat + YOUR_OFFSET), get(cur_vlookat));

use KEEPVIEW and adjust/rotate the the pano image itself by the prealign setting to match the direction:
Quellcode

1

<image ... prealign="0|YOUR_OFFSET|0">
