Take a Look at the GB3D Type Fossils Online Project

Would you be interested in watching fossils of plants and animals long gone in stereoscopic 3D format? Probably not the most fun thing for most you, however for the ones interested the GB3D Type Fossils online project by the British Geological Survey might be of interest as it offers a large selection of detailed photos of fossils in 2D as well as anaglyph 3D photos. Not all, but in most cases, fossil specimens have been photographed as stereo pairs, using a see-saw apparatus dipping 4° from the horizontal on either side and the images have been combined into red/cyan anaglyphs that can be viewed through a simple red/cyan 3D glasses. It would’ve been good if the stereo 3D images were also made available in Side by Side format as this way they could be watched not only in anaglyph 3D format, but on a wider array of 3D-capable hardware, especially considering they are available in pretty high resolution and provide good effect of volume. Anyway still a good educational/scientific resource for those interested in fossils and the availability of stereoscopic 3D images although only in anaglyph 3D format is still a plus.

Phereo 3D Website Further Improves Their Oculus Rift Support

About a week ago the stereoscopic 3D photo sharing service Phereo announced beta support for viewing photos with the Oculus Rift 3D HMD, but initially it did not include the proper distortion of the stereoscopic 3D images that is needed to compensate for the lenses in the Rift. The good news is that Phereo continued to improve their Oculus Rift support and they added the lens distortion in order to make the 3D photos look properly when viewed through the HMD device. Furthermore in order to compensate for the chance that you may see black edges around the top and bottom of some images with wider aspect ratio they have also added what they call ambient light background in order to make the transition at the edges of the photos more seamless. So you should definitely check out the Oculus Rift support on the Phereo website if you happen to have a Dev Kit, some 3D photos shared there do look great now when viewed through the Rfit.

Of course there is more to be done, like for example a bit of improvement around the center of the image where the left and rigth views of the stereo 3D photos connect. Apparently the Oculus Rift mode has been optimized for the A set of lenses for the Oculus Rift and while this works quite Ok with them, if you use the B or C set of lenses the right part of the left view and the left part of the right view gets “cropped” more from what you see so that some objects on the scene could be cut where they are not supposed to be cut (especially for things that pop-out). But as already mentioned the Oculus Rift support available on Phereo is still in Beta stage and we are already seeing good improvement.

Tornado Hellendoorn 3D Rollercoaster Demo for Oculus Rift

September 4th, 2013 · 1 Comment · Other S3D Tech

Just what the doctor ordered – another Rollercoaster demo for the Oculus Rift. If the RiftCoaster is not enough for you to test your resistance to nausea when using Oculus Rift, then this new demo might be just wht you need. The demo looks and works quite well even at the moment, though a bit longer track and a faster speed could be helpful to make it even more fun to try with the Rift. The Tornado 3D Rollercoaster demo has been made by a Dutch company called ArchiVision and is a virtual replica of an existing Rollercoaster in the dutch theme-park “Hellendoorn”.
