The hypothetical Third Dimension…
Gimpel is now free. What does this mean? It means that now you can convert your 2D images into stereoscopic 3D ones. For free. The results in the examples on the website are pretty good, you’ll need some red/cyan anaglyph glasses to appreciate them. From the blurb “Gimpel3D converts single images or frame sequences into stereoscopic 3D using a combination of traditional approaches and a proprietary projective modeling system.”
