Infinite Z's zSpace
"No one contemplated manipulating objects in free space," Infinite Z ceo Paul Kellenberger tells me. The company has been around for five years, spending the first few on researching and developing the parts of the zSpace system. At Autodesk University this week, they unveiled it for the first time; I interviewed Mr Kellenberger last week.
zSpace Product and Branding
The zSpace device consists of a 24" 1920x1080 LCD monitor running at 120Hz. It has to run at that speed so that each eye sees smooth motion, 60Hz each. The monitor is mounted on a stand that tilts it up by about 30 degrees.
Looking down at the monitor, you can see 3D model as a 3D image. You can work on top of the 3D image or inside of it. The company has found that beta testers using software like Maya tend to work closer to the screen; those using CAD tend to work further away from it. For instance, you can orient parts in assemblies precisely in 3D. Another example: you can draw 3D curves around and below objects, without having to change UCS or viewpoint.
You interact with drawings using a wired stylus. For determining its location relative to the screen, the stylus has optical and inertial sensors, such as an accelerometer and a gyroscope. The styles has three buttons: the primary one selects objects, and the other two are user definable. (The stylus is wired in version 1, suggesting a wireless one is on its way.)
You see the 3D image through a pair of polarized, passive glasses. These are not shuttered LCD glasses, and so do not need wires or batteries.
The tablet has a pair of widely spaced sensors that track the glasses, and then rerenders the 3D geometry in real time as you look around the model. 3D models can look like they are floating in the screen, or pop out of the screen.
The company provides an SDK that allows software vendors to interact with make zSpace. The largest number of calls involve interaction, such as with the virtual laser pointer to select and manipulate objects, use a virtual camera to do inspections, and to do 3D sketching for precise piping and routing.
upFront.eZine: Is the monitor specially made?
Paul Kellenberger: It consists of three parts: (a) a special LCD that's made by one company in the Far East; (b) an interior system board that handles the tracking and interaction; and (c) software that makes a small number of calls to the application.
upFront.eZine: How do you select an object in 3D?
Mr Kellenberger: You see a laser or a selection tool, depending on the application. The screen is a virtual volume; the stylus is like a 3D mouse with a virtualized selector.
upFront.eZine: Do zSpace work with 3D mice?
Mr Kellenberger: Yes, with the Space Navigator from 3dconnexion. But we want it to work with many input devices. There is a wearable glove with sensors at fingers, and touchpads, like those Wacom, but we find people prefer to 3D over 2D. We are working on the ability to use your hand, without needing sensors on fingers.
upFront.eZine: Is there feedback?
Mr Kellenberger: There are no haptics (touch feedback), but there is highlighting that depends on how the application implements it. You can do a cubed select: (1) draw a rectangle and then (2) pull it up like an extrusion.
upFront.eZine: How do you zoom in and out?
Mr Kellenberger: You move the whole scene, or an object, closer or further away. You no longer have to wonder what happened in the z direction.
upFront.eZine: What will be the price?
Mr Kellenberger: The developer kit is $6,000 for everything. It plugs into a PC using the DVI or HDMI connector on stereo-capable graphics board from nVidia or AMD/ATI. We found it even works on an nVidia Quadra 1800.
upFront.eZine: When will it be available?
Mr Kellenberger: It is in beta now, and will ship for Autodesk Showcase and Maya in Q1 [Jan-Mar, 2012]. We are working with Autodesk to implement it first, and hope to work with all major CAD vendors.
upFront.eZine: What is your target market?
Mr Kellenberger: The initial focus is on the product design and animation markets, but we also see it in GIS and medical.
upFront.eZine: Who is your closest competitor?
Mr Kellenberger: No one.

The Cloud is Dead?
It's been interesting to watch the title of my piece 'The Cloud is Dead' from http://www.upfrontezine.com/2011/upf-709.htm#a spread as a meme, popping up here and there in the CAD world. For instance, reporting yesterday from Autodesk University, #martynday wrote, "Is Ralph Grabowski in the audience? I think his 'cloud is dead' view is getting beaten to death with a big stick."
The title is, of course, a riff from other literary exaggerations in the generic media, such as "Is God Dead?", "The End of History," and even in technology press, like "RSS is Dead" and "The End of the Email Era."
The dramatic titles signal that a significant change is underway, not that these things are literally dead. For instance, Time magazine's infamous 1966 cover < http://www.time.com/time/covers/0,16641,19660408,00.html > actually referred to liberal theologians for whom God had become dead. For anyone else, such as an atheist, God was never alive and cannot die; for the theist, God always exists, and cannot die.
I wrote the 'The Cloud is Dead' title after thinking about what Steve Johnson and his readers were saying on cad nauseam < http://www.blog.cadnauseam.com>. CAD vendors like Dassault Systemes and Autodesk had been promoting the promise of the cloud for three years by the time Mr Johnson began his series in which he methodically examines the pros and cons of the technology.
As I read his series, it struck me that there are w-a-a- y too many problems for the cloud to work well for CAD users. Readers who got beyond my provocative title know that I made two primary points:
- It takes a maturing process to determine if new technology is useful; its use should be appropriate, not merely because it is new. Second Life, anyone?
- The cloud is as meaningless to heads-down drafters as is object-oriented programming.
The title "The Cloud is Dead" emphatically signaled my discontent with the concept; of all the niches in the computing industry, CAD has the most serious difficulties operating on a cloud -- technical, and legal.
As Mr Johnson illustrated clearly in his columns, CAD on the cloud has some beneficial aspects, but then suffers from flaws that are so serious that it could be rejected entirely. You can read the problems and benefits at Mr Johnson's site, http://www.blog.cadnauseam.com. He ably airs many of the issues, pro and con -- just as dozens of readers from both sides of the debate have aired their opinions in this newsletter.
I consider it significant that (a) only two of the large CAD vendors interested in the subject; and (b) neither addresses concerns raised by enlightened users.
(I feel that "enlightened user" is a better term than "denier," the word used by the representative of a cloud-vested CAD vendor. "Enlightened," because it is crucial to think through the many aspects that surround new technology. In contrast, cloud proponents appear to be the ones in denial, as they cheerfully bypass speaking to the drawbacks, even cheering it with emotional terms like "infinite" and "unlimited"; one even describes it with the word "love.")
There is one issue, however, that I want to emphasize: Trust.
Corporations much larger and much more important than CAD software vendors have dealt with the issue of trust quite effectively. Without trust, banks could barely operate savings accounts, process cheques, provide credit cards, accept debit cards, and perform other transactions. Financial institutions are backed by governments to guarantee against certain types of losses; credit card companies guarantee against fraudulent use. This creates trust. Only risky investments are not guaranteed.
Cloud-vested CAD vendors scoff at the enlightened with this analogy: "We use our credit cards to make purchases over the Internet, so why not do the same with our data." Left unsaid is that they provide no guarantee against loss. Publicly, they talk of the security of Amazon EC2, of server buildings surrounded by barbed wire. Their terms and conditions, however, state that there is no guarantee for the security of your currency, data.
I understand why they don't want to the risk to become an issue, because they are gambling hundreds of millions of dollars and euros on unproven technology.
Sure, I use the cloud, like Google Mail and SugarSync. But not for anything that's critical.
