Twixtor vs StereoTracer September 2012 I came back few weeks ago from the archaeological excavation of Çatalhöyük, Turkey where this year I tried new experiments in the use of 3D technology to document and visualize ongoing archaeological excavations. Last year I did tests on site using Image Based Modeling techniques to document the investigation of the building 89, in that occasion the team of the university of California Merced directed by Maurizio Forte, were running similar experiments using instead a phase shift laser scanner, they got interesting results and the use of both these techniques in the same excavation context gave us a very good feedback on how different technologies that produce similar results (resolute 3D model) obey to different work-flow of data capturing and post processing. After this tests we gain a good knowledge on how making these tools compatible with ongoing excavations and how to manage the data in a reasonable time frame. 3D model of the Building 77 realized using Photoscan AgiSoft

2D to 3D Suite Overview | YUVsoft 2D to 3D Suite product includes a broad range of professional tools, enhancing and simplifying stereoscopic 3D conversion and postproduction for motion-picture and TV content. The product is designed for medium-size VFX and production studios, as well as large conversion studios. It contains both versions for After Effects and NUKE. 2D to 3D Suite offers the following benefits: Depth markup propagation from key frames — decreases number of frames requiring rotoscoping for all or several objectsHigh-quality stereo generation using background reconstruction — automatic stereo generation with an essential minimization of manual workAutomatic generation of plausible depth maps in many cases — rotoscoping may only be necessary for key foreground objects and objects with complex borders Watch the tutorials on Depth Propagation and Stereo Generator basic usage (a playlist of 2 videos). 2D to 3D Suite Tool List: Technical Requirements Licensing See also:

Is Origami the Future of Tech? In 1996 a young mathematician and computer scientist named Erik Demaine became fascinated by a magic trick that Harry Houdini used to do before he made his name as an escape artist. The magician would fold a piece of paper flat a few times, make one straight cut with a pair of scissors, and then unfold the paper to reveal a five-pointed star. Other magicians built on Houdini’s fold-and-cut method over the years, creating more intricate shapes: a single letter, for example, or a chain of stars. It’s an odd subject of study for a computer science professor, but Demaine had an unorthodox background. Photographs by Leonard Greco for Bloomberg BusinessweekCurved-crease origami at Erik and Martin Demaine's shared studio at MIT When Demaine was six, he and his father started a puzzle company. It was his father who brought the fold-and-cut problem to his attention when, still a teenager, Demaine was searching for a dissertation topic. At least in theory.

Twixtor and depth of field : RE:Vision Effects Hi, this is the first time I post on this forum so I introduce myself. My name is Giovanni and I'm and Software Engineer with passion for Photography. I use Twixtor Pro together with an array of cameras to produce 3D pictures to print on lenticular medium. This is my website where you can have a look at the result: Now I have a question. Of course this is a trick, not a real depth of field. To summarise I would like to blur a video uniformily along both x and y axis using the information of movement along the x axis. Any idea? Giovanni ImageMaster | Topcon Positioning Systems, Inc. Previously PI-3000 ImageMaster software is available in four editions, IS, Lite, Standard, Pro. This powerful combination of functionality allows you to accomplish everything from Imaging Station wireless control of measurements to 3D module generation using stereo photo pairs. Four Editions of ImageMaster Software: IS - Controls the IS via WLAN connection and makes 3D TINS and photo textured surfaces of IS collected data only. LITE - Intended for GPT-7000i packages with Field Orientation software. STD - Includes all IS edition features plus additional editing of IS scanned data with full Survey Tools such as volume and cross section calculations. PRO - Includes all above features plus Topcon's advanced photogrammetry solution previously distributed as PI-3000 Photo Modeler software. Features of Topcon ImageMaster IS Edition: This edition compliments the Topcon Imaging Station (IS). The IS edition can collect points and point cloud points from the IS and prepare TINs with photo texturing.

Twixtoring real bullet-time footage ? : RE:Vision Effects Hi Pierre, First, thank you very much for your time and help, much appreciated. I will study those docs you're referring to. We can't shoot on a green screen since we want to use a real environment. If the big strip of paper is the main issue, we could simply consider not putting anything in front of the people for the next tests, though thank you for the "spline" techniques explained. What I really need to be sure of, is mainly about the camera move, and if the amount of frames would be enough to get something close to the footage I gave earlier: (making of, if it can helps...) Since we don't have as many cameras as they do, do you think twixtoring the footage of 50 cameras would do the work ? I know it is hard for you to answer without the material so we're going to do another test today with the fifty cameras, see what kind of issues I get this time... Talk to you again soon. Best Julien

Internet Archaeol. 25. Review of ImageMaster. Anthony Masinton Dept. Archaeology, University of York. Email: Cite this as: A. Masinton 2008 'Review of ImageMaster Close-Range Photogrammetry Software by Topcon', Internet Archaeology 25.

Introduction | ImageMaster | Caveats | Workflow | Summary and Conclusions 1. With the release of Photosynth, Microsoft has taken the quest for the 'holy grail' of close-range photogrammetry one step closer to its goal while also placing that goal in the hands of non-specialists. The quest continues. Some steps have already been taken to bridge the gap between professional-grade photogrammetry and non-specialists. The negative side of all of these tools is that they are web-based. Relatively inexpensive (about £800) local machine solutions have been available for many years. 2. 3. 4.

Re: Morphing between multiple cameras : RE:Vision Effects The simple thing first: 1) RE:Flex Morph allows you to KeyFrame where your still frames are. So in this case it would be a single set of splines you animate in time. 2) You would save yourself a lot of trouble if the dancer was jumping say with his arm by his body as not to create "holes"/layers -- otherwise I am afraid you will have to break the limbs in separate layers and "fabricate" something to temporarily fill holes (parts of a picture not visible from next camera). To visualize maybe raise your hands facing front facing level of your head in front of the mirror and turn 30 degrees increment, next frame your hand is now in front of the head, this is the really hard part with rotations (the part of your head that is now behind the hand on one view). 3) RE:Flex has a magic button called Auto Align which computes optical flow between your stills. However the magic has limits. Pierre
