Generating 360 degree stereoscopic images I've been playing around with generating 360 degree stereoscopic images for use with my Google Cardboard (other VR devices should work too). Basically what I do is generate two spherical image that are offset by 6cm, one for the left eye and one for the right. This are works pretty well, but I've noticed a problem. The problem is that when viewed in the forward direction the 3d effect is perfect, but if you turn around to look behind then it is broken. This makes sense, because looking forward the left image is offset to the left and the right to the right, but looking behind things are reversed so left is offset to the right and vise-versa. My question is, is there anyway to generate images that don't have this problem? Doing some searching I found this article. It says, "We rotate the cameras about their common pivot point..." in regards to the left and right image. I believe that's the problem I'm having. Currently when the spherical image is rendered it's rotating around the virtual visitor's center point, but with the scene viewed from a single eye in the center of the visitor. What I believe needs to happen is that the spherical view is rendered from a virtual eye on the left or right of the person yet still rotating around the center of the person. If my supposition is correct, then the question is, is it possible to change the renderer to do this? Anyone have any experience or thoughts on this? Thanks. |
