Finally i had some time to experiment - the last five hours
.
First i did dremel the fresnels to fit instead of the cup holders in the tree-nozzle holders.
Then i put them in place and tried with the dual screen setup to find a good arrangement. Unfortunately i realized quickly that
1) to build up one (not two) picture in my head i had to slide the fresnels outwards to match the middle of their screen half.
2) because of that i could not use two screens, because the two images are way to far apart for my eyes to converge.
So i was left with one screen but i decided to use only one fresnel and increase the distance to the retina to roughly 10cm.
While fiddeling with the now only taped fresnels and wobbling cardbord housing i fired up vorpX and deadspace (which i was playing recently. What can i say. WOOOOOOOOOOOW!!!
Despite the wrong warping - i could adjust the vignette size to 1.30 which fits well and played with other settings of vorpX but couldn't adjust properly- i am so glad i tried! Because i can see finally far objects! I found myself just walking around and enjoying all the things i did not even realize when plaing on 1080p (riftless, as i did before). And the picture quality is so much better!
Tomorrow i will try to make some pictures, increase the sturdyness of the cardbord housing and put the sensor on the frankenrift
.
I will also ask Ralf from vorpX to halp me with the shader-distortion and maybe also with a option to bring the center of the two pictures closer together. Not IPD but Picturedistance. Then i could use both retinas...
Ahh, yes, one downside: the weight on the head feels much bigger. But i did not try to balance it correctly yet...
Does anybody know how to start the riftcoaster with vorpX? I wanna try it with added far sight!
