Romanesque monuments …

… in virtual 3D. Very cool use of 3D modeling and visualization.

The release:

“With this methodology an exact model of the monuments or places of interest can be obtained in a virtual way”, Pedro Martín-Lerones, co-author of the study and researcher at the Cartif Foundation in the Technological Park of Boecillo (Valladolid), explains to SINC.

The project, which has been published in the Journal of Cultural Heritage, makes it possible to create three-dimensional plans with colour images of historical and artistic places of interest. The data is recorded by laser scanners that take the maximum number of geometric measurements from a minimum number of positions.

“This ensures that accuracy is maintained, whilst also reducing the time spent on field work, because generally more shots are usually taken than are needed”, comments the researcher, who also explains that a three-dimensional model of the monument is produced “with millimetric accuracy, in comparison to the centimetric nature of conventional 2D templates”.

The data provided by the laser scanner is complimented by images captured by photographic cameras. This information is processed using two specific software programs developed by the researchers themselves: one which superimposes the information in colour of the photographs onto the three-dimensional model, and another that generates the final plans in 3D in a timeframe that is 40% quicker than the traditional method.

Martín-Lerones highlights the many ways this study can be applied: “It makes it easier to draw up intervention projects, as well as preservation and renovation projects on churches or other buildings, in addition to its potential uses for popularizing –on the internet, for example- the monuments in 3D”.

Information that is thousands of times better

The team has tested the methodology in five churches in the old Merindad de Aguilar de Campoo, located between the provinces of Palencia, Burgos and Cantabria. Of all those digitalized, the Palencian church of Valberzoso turned out to be one of the most representative, thanks to its artistic value, state of preservation and accessibility.

“There, it can be observed that by using three-dimensional measurement of a place of cultural interest the result is that the quantity of information captured is thousands of times better than what is obtained from conventional methods, whilst the time spent on field work is reduced by around 75%”, Martín-Lerones points out.

In the Merindad de Aguilar de Campoo the highest number of Romanesque artistic monuments in the world can be found. Since 2005, it has been declared a Heritage Site by UNESCO and it is presenting an application for European Heritage again this year.

VanDuzen’s latest — Vouch Software

Filed under: Business, Technology — Tags: , , , , , , , — David Kirkpatrick @ 2:37 pm

Got a call from Nancy Hairston, founder and president of VanDuzen, last week with some exciting news. The 3D visualization and modeling company is about to officially release Vouch Software.

Vouch is geared toward designers and manufacturers of toys and products for infants and allows for digitally testing designs. This tool will be a tremendous time and money saver by pushing basic safety testing back into the design phase using 3D virtual models instead of physical prototypes.

One designer who used Vouch in beta said she even ran tests while designing and made changes on the fly instead of creating a finished product for testing. Pretty cool.

From the link:

“These days you have to design safety in. If you wait until after the toy
is made, it’s way too late. You can’t do it after the fact.”

Vice-President, Safety, Security and Social Accountability – McDonald’s
As quoted in Chicago Tribune.com, August 5, 2007


What our other customers are saying

“Vouch gives me results faster than I can fill out the paperwork
requesting the rapid prototype for testing.”

“I run tests in Vouch concurrently while I design in Rhino, it is so fast.”

“We design digitally…why not test digitally.”

Shapeways offers online 3D modeling tool

Filed under: Arts, Business, Science, Technology — Tags: , , , , — David Kirkpatrick @ 5:28 pm

I blogged about Shapeways a couple of weeks ago here and the latest update about the consumer 3D company popped up in the inbox today. The company is announcing the Shapeways Creator Engine, an online tool for 3D modeling.

Like I mentioned in my earlier post on Shapeways, I do communications consulting for a company in the 3D visualization and modeling space and it’s a fairly esoteric and very expensive industry for operations at any level.

The high end will remain up in the stratosphere, but I think it’s great Shapeways is bringing this tech “to the masses,” so to speak. Without having a closer look at its tools and process, it seems Shapeways is offering a reasonable entry into the world of 3D visualization and modeling for professionals and hobbyists alike.

Here’s the release sent to me today:

SHAPEWAYS LAUNCHES NEXT GENERATION DO-IT-YOURSELF (DIY) ONLINE PRODUCT CUSTOMIZATION AND PERSONALIZATION:  SHAPEWAYS CREATOR

 Shapeways Creator Enables Affordable Personal Design and Manufacturing with New Easy-To-Use 3D Online Customization

August 12, 2008 – Los Angeles, CA- SIGGRAPH, Booth #138 – Shapeways, a new platform and global community for 3D-design and production, takes
a major step towards the next generation of consumer co-creation with the announcement of the Shapeways Creator Engine. For the first time, consumers without 3D modeling skills can shape, mash, imprint and design their own 3D products in just a few mouse clicks at Shapeways.com. From lamps with a personal message to fruit bowls linking back to memorable moments, the Shapeways Creator Engine has a beta library of predesigned product templates which is expected to
grow rapidly over 2009.

“We recognize the desire of consumers who want to own or give something that is unique and has their special, personal touch,” commented Peter Weijmarshausen, CEO of Shapeways. “With the Creator Engine, now anyone can participate in the artistic process and create something that is truly a reflection of their own needs and tastes.
With the Creator Engine, we have broken the currently existingtrade-off between freedom of design and the complexity of the design process.”

“In today’s world, consumers are universally less and less satisfied with the choice that the usual shops offer,” said Jochem de Boer, CMO of Shapeways. “Instead, they are looking for ways to reflect their personal identity in the objects that they choose to have around them, or that they carefully select as a unique gift for their loved ones.”

Shapeways offers 3D modelers an affordable, web-based platform to share and produce their designs imported directly from popular 3D modeling software via a technique called 3D printing. Shapeways verifies objects to ensure printability and provides a real-time cost estimate. Within 10 working days, a tangible 3D product will be produced and arrive at the consumer’s home globally.

High tech art fraud detection

Filed under: Arts, Business, Media, Technology — Tags: , , , , , — David Kirkpatrick @ 3:19 pm

VanDuzen Archives, the fine art division of VanDuzen Inc., was featured in a Design News story today. Full disclosure — I provide communications consulting for all three divisions of VanDuzen Inc.: VanDuzen Archives, SculptCAD and MedCAD. VanDuzen is a Dallas-based 3D visualization and modeling company operating in a number of industries.

From the link:

The VanDuzen Archives of Dallas has built a growing business around the use of imaging hardware and digital shape sampling software as tools to authenticate and conserve works of art. And in one recent job, the company helped ferret out a forged copy of Picasso’s Tete de Fernande, a bronze bust.

Speaking at the SME’s Rapid 2008 conference, VanDuzen president and CEO Nancy Hairston recounted how a major New York auction house, which she wouldn’t name because of confidentiality agreements, had become suspicious of a Tete de Fernande bust that one of its client wanted to put up for auction. The bust had supposedly been cast, in the 1920’s, from Picasso’s original plaster molds.

Art experts seeking to authenticate a casting such as this usually take a series of linear measurements using calipers and then compare the measurements to authenticated versions of the same casting. Size deviations bigger than shrink values for the cast material are one indication that a piece is just not right.

In the case of the bust, initial linear measurements showed it to be 15 percent smaller than three authenticated castings–including ones at the Tate Gallery in London and the MOMA in New York. “Bronze shrinks approximately 10 percent from the plaster molds, so that wasn’t a possible shrink value,” Hairston says.

To be sure, though, the auction house turned to VanDuzen, which took a high tech approach to measuring the sculptures. The company first digitized the suspect bronze as well as three authenticated versions of the Tete de Fernande using a portable Konica Minolta VIVID 9i non-contact digitizer. Hairston recalls that it took about 150 scans and six hours to digitize each piece.

The scan data was then analyzed using using digital shape sampling and processing (DSSP) software from Geomagic. The software let VanDuzen perform deviation studies that would be difficult or impossible to do accurately with linear measurements. One study that compared the total volume of the suspect bust with those of authenticated pieces. And another, a registration study, showed how well the busts line up with one another.

And it turns out they didn’t line up at all. Hairston says the registration study revealed that the suspect bust was off kilter due to the addition of excess material on its base. “Forger added material to the base to throw off liner measurements,” she says. Once that excess material was digitally trimmed, the suspect bust turned out to be 20 percent smaller than the authenticated models. “That’s what sunk the piece,” she says.

The Kinko’s of 3D printing

Filed under: Science, Technology — Tags: , , , , , — David Kirkpatrick @ 12:32 am

A company I provide communications consulting for is in the 3D visualization and modeling space. The modeling involves “printing” a 3D image in polymers. A very cool and very expensive process. I’ve held a printed hand that exactly matched the original scan — size, fingerprints, everything. But, instead of soft flesh it was a rigid piece of white plastic.

This Technology Review story covers a new online service providing access to 3D rapid prototyping for anyone with a 3D modeled item in ready data form. A real breakthrough in putting cutting-edge technology in the hands of the masses.

One application of rapid prototyping 3D data is “mass customization” — gaining the benefits of mass production for customized items. And it significantly speeds up the development process.

From the link:

Currently, such 3-D printers–in which successive layers of different polymers are sprayed gradually, building up a 3-D object–are very expensive, says Peter Weijmarshausen, CEO of Shapeways, a spinout from Philips Research, in Eindhoven, the Netherlands.

But the new service, launched last week, makes this technology accessible to anyone: budding artists, architects, product designers, and general hobbyists. A small design company might want to make samples to show a client, or an artist might want to make copies of the same sculpture created digitally, for example.

“From a technology viewpoint, Shapeways is not that new,” says Weijmarshausen. “Rapid prototyping has been used by the aircraft and automotive industries for years, but now we’re making it accessible to consumers.”

Users submit their design in digital form, after which Shapeways’s software checks it over to ensure that it can be made. Shapeways then passes the design to its production line of polymer printers, delivering the tangible object within 10 days of ordering, with prices typically between $50 and $150.

3D virtual “touching”

Filed under: Science, Technology — Tags: , , , — David Kirkpatrick @ 3:34 pm

This technology is very cool. The release is titled “Doctors will soon be able to feel organs via a display screen.” Not sure about the internal organ part, but this is going on right now. I know because I did it this week.

I’m beginning to do content consulting for a 3D visualization and manufacturing tech company. During a crash course in what they do I used this technology to “touch” a virtual bone while viewing the bone on a monitor.

From the release:

Erik Vidholm, at the Center for Image Analysis at Uppsala University, has taken part in the development of such interactive methods where the mouse and keyboard are replaced by a pen-like three-dimensional mouse that enables the user to feel the virtual organs. This is called haptics. Computer models are adapted to the images of organs and can then be used to measure the volume of the organ, for example, or to calculate changes in shape and migrations.

The pen-like device is very cool, and this technology will continue to be an amazing breakthrough in medicine. My client is already helping surgeons perform virtual surgery before making any cuts, sometimes finding additional problems making the actual surgury more precise with fewer surprises.
