Hello everyone
Again I post in the beginners section because what I want is probably obvious for advanced users.
For stereo panos we can put hotspots at different depth levels, so they appear at the wanted depth in the 3D space. It means that when in stereoscopic/3D mode any hotspot will have a particular relative position in the left view, and another relative position in the right view, so that it appears in correct relative depth/distance when we view in stereo. Also any stereo pano can be rendered in monoscopic/2D mode, in that case I think the default view used is the left one. The default hotspots are shared between mono and stereo modes of the panos, so logically in monoscopic mode the hotspots positions should be the same as the ones of the same hotspots in the le left views of the stereoscopic mode. But It seems it is not the case. I tested with several stereo panos and it seems that it is reverted, so that the position of any hotspot in the monoscopic mode is the same as the position in the right view of the stereoscopic mode. This is not very visible but it can be a problem in some cases, especially when hotspots are near some objets that are not at the same depth level in 3D space, because it will create some unwanted superpositions, either in 2D or 3D modes. Maybe it is a bug in krpano, because for me it seems the situation should be logically reverted. Maybe it is possible to overcome this by setting the 2D mode with the right eye views but I didn't see yet how to do that.
Also I think it is possible in krpano to use 3 views for each stereo pano, one for left eye, one for right eye, and a "middle view", used to render the monoscopic/2D mode. Of course it depends on the stereoscopic acquisition method used, in some cases you only have the left and right views, but you can also have "middle" view with "angular stereo" methods. I have many panos rendered with this method (with left-middle-right views), and even with multiple stereo bases distances for left and right. So in the case of 3 views for each pano, the hotspot positions of the monoscopic/2D mode should be set at the "middle" of the positions in the left and right views of the stereoscopic/3D mode. Are all these things already easily possible to set in krpano ?
I have some others questions/ideas about stereo panos but I will keep them for other threads.
