The same picture is made into html5 with pano2vr. I use simple vr player and deovr player to open the picture without any special effects, which is the same as what I saw in the vr tourviewer rift.
But when I open webvr with a browser, the picture will be blurred and the color contrast will decrease.
At first I just thought that recently I like to use vr player to watch 360 pictures instead of webvr. I accidentally found that opening webvr with a browser in the past few days has become blurred. After comparison, I understand the reason.
