Mesh2Flash and CCD Cameras ======================== EXTRACT FROM: DAVID Newsletter ======================== In This Newsletter * Mesh2Flash: 3D Internet Presentation for Free! * New CCD Cameras, Laser, and Whiting Spray * Credit Card Payment * New DAVID Version 2.4.5 * How to Update Mesh2Flash: 3D Internet Presentation for Free! If you want to present your 3D models on the Internet, e.g. in your online shop or a forum, we have just the right tool for you: Mesh2Flash! Simply embedded in your web page, this little Flash program allows the viewer to freely rotate and zoom the 3D object by mouse. Mesh2Flash really renders the object live, instead of showing just a few fixed shots like many other \"3D\" viewers do. It will directly load scans made by DAVID or other OBJ or DAE files - with or without texture. Only Adobe Flash Player is required, which >98% of your visitors have installed anyway. Some examples and helpful information can be found in our Wiki and Forum. New CCD Cameras, Laser, and Whiting Spray We proudly present our brand-new high-quality industrial CCD cameras! These camera models have been specially designed for scanning with DAVID. They are based on models from a German brand manufacturer which have been proving to give excellent scan results for years! Their low-noise CCD chips capture XGA resolution at 30 FPS, thus allowing high-precision scans with hardly any noise or waves in just a few seconds. Together with their high-quality Pentax lens, they are aiming at most demanding users. These cameras aren\'t cheap, but definitely worth the money! Currently we offer two models, a monochrome and a color camera. The monochrome model captures the laser line at a slightly better resolution, but of course is not able to create a colored texture shot of the object\'s surface without additional filters. Both models offer a trigger input which may be used in automated setups, e.g. for synchronization with a stepper motor. Scanning objects with dark or shiny surfaces has always been difficult. Therefore we now offer a convenient Whiting Spray for a low price. A thin layer of whiting will make scanning easy, preserving even small surface details. The whiting can be washed off easily in most cases. However please be warned not to use the spray on expensive or sensitive surfaces - first make sure you will be able to remove it perfectly! Furthermore there is a new line laser model: The LE650-16-3-F-S(22x100)90 with included battery and adjustable focus emits a strong and thin red line with a power of 16mW. This helps scanning of large objects or in difficult environments - even when there is no wall socket available. All products and detailed information can be found in our online shop. By the way, credit card payment is now possible! New DAVID Version 2.4.5 Of course development of DAVID is successfully moving forward! We would like to mention two new features: Mesh Density Reduction is very helpful for preparing a scan for Mesh2Flash. It can reduce the number of vertices and triangles significantly, making download and rendering speed much more comfortable. Of course mainly flat surface parts will be reduced, edges and borders of the mesh will maintain their shape. And the texture will not be touched either, which is important for a nice visual impression and may compensate for a low-resolution triangle mesh... Want to scan faster? Structured Light may be an alternative to a slowly sweeping laser line. The new DAVID version supports this method - it\'s still experimental, but works fine already! The basic idea is to use a video projector to illuminate the scene with a few (e.g. 12) different stripe patterns. If you use a still photo camera, e.g. an SLR, you can shoot those 12 images manually in very high quality. The software will extract detailed 3D data from only these few images. More details can be found in this Forum thread. Some more small improvements and bug fixes are listed as usual in the changelog.
Version 2.4 and new lasers ================================ EXTRACT FROM: DAVID Newsletter ================================ ================== DAVID Newsletter ================== * New DAVID Version 2.4.2 * DAVID Starter-Kit and New Line Lasers * Incredible User Results * How to Update ========================= New DAVID Version 2.4.2 ========================= Finally, the new grabber has found its way into DAVID! It makes DAVID 2.4 compatible to more different cameras and performs faster on most hardware. Give it a try! http://www.david-laserscanner.com/?section=Downloads As usual, there are some more nice improvements both for beginners and pros, like: Increased precision We have improved lens un-distortion and calculation of the 3D laser light plane position, reducing deformations and waviness of scan data. Default camera parameters included Setting up the camera parameters is one of the most difficult steps for beginners. For some camera models, DAVID has default parameters that will help you get started. Of course some adjustments will be necessary, since every setup is different... COMmunication For those who automate their scanning setups, DAVID has improved capability of communicating over a (virtual) COM port in both directions. You can control many DAVID functions remotely, or even synchronize single camera frames to laser motor steps, which is especially interesting for Scanning Without Background! Details can be found in the user manual: http://www.david-laserscanner.com/wiki/user_manual/com_port and more Please see the complete list in the changelog: http://www.david-laserscanner.com/wiki/david-release-history ====================================== DAVID Starter-Kit and New Line Laser ====================================== As presented in our previous newsletter, the DAVID Starter-Kit is available, and it contains all hardware necessary to set up a 3D Scanner. Best quality you can get for a price that low! For those who are building their own setup, we have new battery-driven line laser modules with adjustable focus in our shop: a green and a red one (LE532-5-3-F-S, LE650-5-3-F-S). Our favorite webcam Logitech QuickCam Pro 9000 is available at a low price, including a specially designed stand! And industrial cameras are coming soon... http://shop.david-vision-systems.de/index.php/language/en In the meantime, we have found a large number of distributors all over the world, so whatever country you live in, there's a good chance that you will find a reseller close to you. See here: http://www.david-vision-systems.de/index.php/contact More details about the Starter-Kit: http://www.david-laserscanner.com/?section=Starter-Kit
StarterKit and V2.3 ================================ EXTRACT FROM: DAVID Newsletter ================================ * DAVID Starter-Kit Available! * New DAVID Version 2.3 ====================================== DAVID Starter-Kit Finally Available! ====================================== High-precision 3D scanning at an unbeatable price! We proudly present the DAVID Starter-Kit, a package that contains everything you need to set up your own 3D Scanner: * The best webcam we could find * A great, wireless line laser module with high-quality optics and adjustable focus * Precise, solid calibration panels in different sizes * and of course DAVID-Laserscanner software (full Professional Edition) on a USB flash drive ======================= New DAVID Version 2.3 ======================= DAVID Version 2.3 is available for download now! It has some improvements that are interesting both for beginners and experts: Small but useful: Scan Quality Feedback. One of the major difficulties for beginners is adjusting the camera settings like exposure and focus. Now DAVID helps you optimize these parameters by showing an evaluation of the image and laser line quality during scanning. Just try it! See manual pages for details. For Professionals: DAVID controls your motor-driven laser. As introduced in our last newsletter, it is helpful to move the laser by motor. This is more convenient, and allows you to scan without background panels. Now,DAVID is able to control your laser by sending some configurable commands through a (virtual) COM port. For the time being, you will have to build some micro-controller based hardware to drive your laser, but we are planning to offer some complete solution in the future. Thanks to our great community members, the new version offers two more languages. So DAVID\\\'s user interface and user manual are now available in English, French, German, Italian, Polish, Portuguese, Russian, and Spanish! Have Fun! Simon & Sven

DAVID update V1.6 New DAVID Version 1.6: 1. Scan alignment mode \"Rotation around axis\" allows to specify a known angle of rotation (useful in conjunction with a turn table). 2. Command File Interpreter in DAVID-Shapefusion: You can script theShapefusion procedure and let it run without any user interaction. 3. Laser plane calculation is now more precise even with strong lens distortions. 4. \"Fast\" scanning mode (may increase scanning speed on slow PCs without loss of precision). Additionally we have updated the \"AngelScan\" video, which you can use to test DAVID without needing your own setup. We have created the new video with better camera and laser hardware, so it shows much better what great results can be obtained with DAVID! And don\'t forget to have a look into our new DAVID Laser Shop! here you will find inexpensive line laser modules, which have proven to be perfectly suitable for laser scanning with DAVID. We wish you a Merry Christmas and a Happy New Year!
DAVID update V1.5 DAVID 1.5 - small but mighty! To put it in a nutshell: 1) Enhanced sub-pixel detection of laser line and increased scanning accuracy. 2) Alternative 'Poisson' mesh fusion method, which is more robust against inaccurate scan alignment and which gives water-tight results. 3) 'Combine'-Button for grouping/combining of multiple scans to one scan. 4) Much faster fine registration. 5) Possibility to save all scans in one file (without fusion step). Good Scanning!
DAVID update V1.4 Better and better every time... We have just released DAVID-Laserscanner and DAVID-Shapefusion Version 1.4. Once again, you will find some useful improvements: The new version allows you to grab textures and to view the texturized model in 3D. DAVID-Shapefusion loads and displays the texture when you add a scan. A texture fusion is still under construction. DAVID-Shapefusion 1.4 now includes an OBJ-, PLY-, and a new STL-export filter. STL stands for "Standard Tessellation Language" and is a common 3d format that can be imported e.g. by many CNC milling machines. Furthermore, you will find a new experimental "thin shadow line" mode for using a shadow line instead of a laser line, and many more improvements like an FPS indicator and buttons inside of the 3D window. Good scanning!
