What is a Virtusphere?

A virtusphere is a virtual reality device that basically consists in a big sphere inside which you enter and run like a hamster. It uses to work combined with other virtual reality devices.

The hardware registers your movement so your avatar moves with you while you are actually walking inside the sphere.

An interesting article of someone that has tested a real virtusphere is here:

Also have a read to his blog, as you may find it a really interesting one.

And finally, here's a video of a virtusphere:

How To Use Xj3D Library In Netbeans IDE

These are instructions on how to use Xj3D libraries in Netbeans IDE so you can integrate them in your Java application. This tutorial is useful for people that are developing Java applications with Xj3D as a library. If your Java application needs a 3D window that shows X3D or VRML, the best way is to use Xj3D.

Yes, it's Java, but not the programming language. Photo by JpSlim.

You just need to install Xj3D, the Java SDK, and Netbeans IDE. Ignore any document that tells you to install more things. You don't need to set any system variable. Ignore all that.

Follow these simple steps:

1) Install Java SDK (Java SE) 32 bits. There were some problems with the 64 bits version, so install the 32 bits version.

2) Install Xj3D.

3) Install Netbeans IDE.

4) Create a NetBeans project: Java Application.

If you just want to run the Xj3D examples, specify "with existing sources", and use the folder examples/sai as sources.

5) In the menus, select: Tools -> Library Manager -> New Library. Call it for example "Xj3Djars" or whatever you like. Click OK.

6) Select the library that you have just created and add everything in the "jars" folder of Xj3D.

In Windows, it uses to be in C:\Program Files\Xj3D\jars

In Ubuntu Linux, look into: usr/local/Xj3D/jars (it may be in other folder, but for me it was there)

7) Right click on the project -> Properties -> Libraries -> add Library -> Xj3Djars -> add Library

8) In the Project Properties window, select Run -> VM Options

9) In VM Options type this:

If you use Windows XP:

-Xmx450M -Djava.library.path='C:\Program Files\Xj3D\bin'

In Ubuntu (I prefer Fluxbuntu) Linux:

-Xmx450M -Djava.library.path='usr/local/Xj3D/bin'

10) Click OK.

That's all!


Working With Netbeans IDE And X3D Or VRML

Now that you are working with your application that uses X3D or VRML, you will work faster and better if you could read easily and create X3D and VRML files from inside Netbeans IDE.

I had the same problem, so I created the free X3DV Module Suite.


The X3DV Module Suite is a free set of modules to code in X3D and VRML, the open standards for interactive and immersive 3D on Internet. With it, you can create virtual worlds in 3D, using the great edition features of Netbeans IDE.

This Module Suite is for coding in VRML and X3DV (X3D classical VRML encoding, the easy to read .x3dv files).

Just have a look at its section. The advantages of using it are obvious. It is also compatible with X3D-Edit, as it's shown in their website. You can use X3D-Edit for X3D files in xml format, and the X3DV Module Suite for X3D files in classical VRML encoding, and for VRML files.

If you like the X3DV Module Suite, you can help its development by making a donation. If you can't, another way of helping is voting it in any social bookmarking site, or simply voting it in the Netbeans Plugin Directory.

LivePlace Video Controversy And Photorealism

These days there were rumors that said that a new photorealistic virtual worlds platform was coming. This has generated a double controversy: whether virtual worlds do need to be realist, and how much the intellectual rights of content developers are respected. The reason: the promotional video of this product.

Copyright Violation?

TechCrunch posted a video that was shown as promotional video of LivePlace, and was retired from their website for some reason.

You can see that portions of this video come from a 3D artist portfolio located here. It is not clear why they retired the video, and it is not clear if this artist works for LivePlace or not, or if he/she allowed them to do this or not.

The comment at TechCrunch, that revealed this, says that this video portions were "stolen".



Each day, we find more examples of the lack of respect for 3D artists and developers that big companies show.

Seems that not only unscrupulous individuals, but also businesses and big companies have loss all kinds of respect for the creators of content, and they just grab and run with it.

This is becoming a real problem. Some people, feeling shielded by their wealth or a false idea of anonymity for being hidden behind great trademarks, think they can abuse less known content developers.

We all must collaborate against this, as content is being devaluated endlessly. Many people look to content like a free-for-all box of trash.

Many people place their content in Internet only under certain conditions, and these conditions must be respected.

Companies have also to learn that if they employ these content developers, instead of stealing them, they'll grow over a stable foundation. If they don't, they will just harvest their own ruin, as they're killing the way of life of many of these creators. And because each day there will be less people willing to share anything.

Having said this, there's a big number of companies that defend the rights of content developers and artists, and no host or domain provider tolerates copyright infringement.


Photorealistic Worlds?

LivePlace says to have a photorealistic virtual worlds engine, that will equal the quality seen in 3D movies. To simplify, these kind of technologies get this spectacular results by rendering the frames using a big server farm. Then, the images are sent to the clients (PCs, mobile phones, PDAs).

As you may suppose, the limitations are bandwidth and server power. The server power can be improved with enormous quantities of money, as these images are generated not by a single server but by an huge army of servers.

The bandwidth is the real limit, and not only the server bandwidth. The client bandwidth is the key. Yes, you will receive superb images but your mobile phone or PC will need to be fast enough to download and display them at speed of light (well... much less, but you know what I mean). Otherwise, you'll suffer a big lag.

In the future, this may be more viable. Now, it's utopian.

Having said this, if you take some time watching the video, you'll see that there is a strange mix of the excellent content of the video by the 3D digital artist, and real world images.
There's also some images of some very basic 3D sceneries that don't look realist at all.

You can see some lights that seem to move at render time. But lights can be simulated by simply using transparent images attached as textures to primitives. Also, things like buildings that seem to be highly realist often are just boxes with high quality textures, and no real complex geometry.

In most of the length of the video, there's a lot of blur and movement that distracts the eyes.
These 2 resources, movement and blur, make your mind imagine what you don't actually see.

So don't trust promotional videos like this, that show things in a frenetic movement and blur.


Conclusion

I see an special emphasis in trying to get photorealistic worlds in the last times, and it's something I just can't understand.
It's not the quality of graphics, but the expression they give, what makes virtual worlds immersive.

If users want a virtual world that seems totally real, why not just go out and meet the real world? What users want is a virtual world that can trigger their imagination, their taste for mystery, wonder, or adventure.
Realism is good for a while, but a virtual world that makes its users feel special, keeps them forever.

News: IM For SecondLife, and AC3D

Instant Messenger For SecondLife?
Linden Lab has registered the trademark SLim, and many think that this may be an instant messenger for Second Life residents. Read it in Virtual Worlds News.

AC3D Can Import Triangles And Boxed Objects Into SL:
Bruce Lehmann (a.k.a. Omind), administrator of the World Builders And Developers community, and one of our most valued readers, has called our attention about the affordable modeling program called AC3D (only $79.95). AC3D has plug-ins for importing triangle (.tri) and boxed objects into Second Life. Read more here. AC3D can also export to VRML and X3D.
