Roger Williams Posted April 12, 2017 Share Posted April 12, 2017 By which I mean, which functions can recognize an equirectangular image for a 360 x 180 degree panorama and ensure that the two sides of the image that will form the seam are given similar treatment so that there is no obvious seam viewing the entire VR image? Or perhaps I should phrase it the other way around: are there any functions that will often make seams visible because they do NOT try to equalize processes on both sides of the seam?

Staff Lee D Posted April 21, 2017 Staff Share Posted April 21, 2017 Hi Roger, Welcome to the forums. The tools won't know you making adjustments on an equirectangular image, it's basically a view mode. Most global adjustments should be ok as they affect all the pixels in the same way. Local adjustments such as tone mapping, haze removal and sharpening may affect how the seam is viewed/visible especially if a high radius is used.

Hi Lee, Yes, that's what I figured, since there are no specific 360 toggles for treating both left and right edge as part of the same image region. The only workaround (for the moment) would be to temporarily add a copy of one of the edge regions to the other side, i.e. extending the horizontal field of view beyond 360 degrees (may need to go as far as adding half an image or 180 degrees). Then taking a crop from the center (width equal to 2x height) should have smooth transitions. But it remains a bit of a kludge (and needs checking of Zenith and Nadir for visible changes). It would be useful if e.g. the Tonemapping persona would have a 360-degree option/toggle, but I understand that it would take some serious code changes.
