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. |

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:

=======================
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!

DAVID Version 2.0! After more than 6 months of work, DAVID Version 2.0 is finally available!
These are the most significant new features:
Texture Fusion: Now DAVID can not only grab textures for each scan, but also align and fuse the textures along with the scans!
Improved Comfort: DAVID 2.0 remembers the different camera settings for calibration, scanning, and texture grabbing, thus you do not need to adjust them again and again! Also you can forward your scans directly to Shapefusion with only one click. In Shapefusion you can combine and un-combine scans for easier handling. Et cetera...
Multi-Language Support: In addition to the English version, the user interface and the user manual of DAVID are now available in French, German, and Italian. A Spanish version is coming soon!
Manual cleaning tool: This tool allows you to remove undesired surface parts from your scans very easily with your mouse.
Increased maximal resolution of Simple and Poisson fusion.
New design: Looks great! And the new colored Scan Result window gives a better impression of the scan quality already during scanning.
...
...
A full list of changes can be found in "changes.txt" which is included in the download as usual.
Furthermore, as an alternative to the download version of DAVID, you can now choose to buy DAVID on a 1 GB USB flash drive. This allows you to carry DAVID around with you and start it directly from the USB drive on any computer!
Always have a good scan!

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! |
