Immersive Technologies

This page is devoted to Immersive Technologies, which includes the photographic technologies (QuickTime VR, IPIX, Reality Studio, etc), 3D technologies (VRML, QuickDraw 3D, etc.) as well as 3D modeling tools.
The individual technologies are listed below.

Photographic Technologies
The immersive technologies listed here all use panoramic photographs to create the illusion of exploring a 3D space. A playback window displays a section of the image, and the user can then click and drag to "look around" the scene. These technologies warp the photograph to maximise the illusion that the user is looking up and down within the real world rather than just scrolling about within a flat panoramic image.
Of these technologies, only IPIX and SmoothMove provides spherical projection (the original image covers the entire Field of View so that the user can look up and see the ceiling.)
This difference not withstanding, most of the differences between these technologies are in various additional features (such as Objects, linking, support available in third party tools, and the functionality of the stitching tools.)

Creating Panoramic images
Most of these technologies require a panoramic image to produce the scene that the user will explore. While they also support partial panoramas (less than 360 degrees around) most of the time a full panorama will be created. There's at least three different ways of creating a panorama;

  • use a fish-eye 180 degree lens and "stitch" the two photographs together
    only
    IPIX uses this technigue
  • use a panoramic camera
    these cameras are expensive and produce unusual negatives that may be difficult to scan
  • use a panoramic lens
    See our
    review of the Be Here Portal 1 lens
  • use a regular camera, wide angle lens and tripod and take multiple pictures
    this requires using a software application to "stitch" the pictures together into a panorama.
    Once you include the cost and time of processing this method can get expensive if you are creating lots of panoramas.
    There are four stitching applications available:
    • Apple's QuickTime VR Authoring Studio
    • Rounadabout's Nodestar
    • Live Pictures PhotoVista
    • Spin Panorama

Other Stitchers
Enroute Imaging's QuickStitch 360 for Mac/Windows, panorama stitching software. QuickStitch 360 automatically combines overlapping photos into panoramic images up to 360 degrees. <www.enroute.com>

Panavue's Visual Stitch, for Windows 95/NT. Their stitcher is supposed to be particularly adept with very large images.Demo versions of these programs can be downloaded from their website. <www.panavue.com>

Want to create a QuickTime VR panoramic scene by painting it rather than using 3D software or shooting a panoramic photo? André Plante has a VR Painting Tutorial and demonstration file at his website. It looks like a lot of work, but some of the techniques might be useful when manipulating existing scenes.

QuickTime VR

Quicktime VR is perhaps the best-known technology. It is widely supported and there are some excellent tools for building panoramas and objects (though the best tools are only available for the Macintosh.)
QuickTime supports both panoramas and object movies.

Reality Studio

Reality Studio from Live Picture grew out of Real Space, which itself was developed by one of the originators of QuickTime VR. Reality Studio supports photo panoramas and objects, but it also supports VRML (.wrl) files inside panoramas. It's the easiest technology (at the moment) for creating panoramas with sprites within the panorama.

Surround Video

Surround Video was developed by Black Diamond consulting, and was originally developed for Microsoft, who then licensed it back to Black Diamond.
Surround Video Freestyle Suite 1.0 was released in July 1998. This featured version 3.0 of Surrond Video, plus new tools for creating object movies and for adding sound to movies.

Surround Video Freestyle Suite 1.0 includes: Surround Video 3.0 Editor, Rotate This! 1.0 and Hear This! 1.0. Rotate This! creates object movies from jpg or bmp images and supports hotspots with text. Objects can be displayed on panoramas or on other objects. Hear This! adds multiple sounds to images and offers individual volume control for each sound.

The authoring tool is Windows only, but browser plugins for Mac and PC are available.

Surround Video Freestyle Suite costs $199.00. A Web Certificate, required for additional domains hosting Surround Video costs $99

IPIX

IPIX is unique in that they offer a stitcher that takes two images taken with a 180 degree fish-eye lens and stitches the two halves together to create a single panorama that covers the entire field of view. Their routines for doing this are protected by patent
Of special note, IPIX released (July '98) a Macintosh version of the IPIX authoring tool.
Pros: Only requires two images. You can see the ceiling!
Cons: Licensing is based per image (from $25 per node). Lighting the scenes may be a problem. Lower resolution (though probably not a problem for the web)

IPIX Mac Wizard runs on all PowerPC configurations with a minimum of 64MB of RAM. The Mac Wizard is priced at $349.95

CycloVision's ParaShot, is a one-shot 360° digital imaging attachment. The ParaShot looks cool! Similar to the Be Here Portal 1 lens, (which we recently played with) but at a tenth the price. The Parashot incorporates 360° imaging optics and unwrapping software, that is compatible with Agfa's Photo Genie. Like the Portal 1, the ParaShot captures a donut shaped image (ParaFrame), which is then unwrapped using the ParaViewer software. With the ParaViewer software, users can navigate the 360° image with pan, tilt and zoom capabilities on the Web or within new media applications with the click of a mouse.

The ParaShot has a list price of $995. Example images can be found at CycloVisions' website.

<Our review of the
Be Here Portal 1 lens>

Be Here Corporation has introduced the Be Here Portal S1 Plus, a second-generation version of their 360-degree lens system that is suitable for stopping action in environments with motion. The Portal S1 Plus costs $4,995 and is Nikon and Canon EOS mount-compatible and offers a lighter weight design for improved ease-of-use and mobility.

Be Here's Portal S1 Plus features an improved optical design over the original Portal S1, resulting in improved image quality and a higher speed f/8 lens. The Portal S1 Plus is capable of operating with a camera at shutter speeds up to 1/500th of a second - a speed suitable for stopping action in environments with motion.

Tips

Tips for creating photographic immersive environments.

If you're looking for a digital camera the Nikon CoolPix 900 has been receiving some very positive reviews.
Of particular interest for those producing sequences of images for stitching into panoramas, the 900 includes an exposure lock which will look the exposure setting used for the first image in a sequence and use it for the rest.
NOTE: Some people actually question the effectiveness of using exposure locking with a digital camera. They argue that because of the narrow exposure lattitude of digital cameras you are better off exposing each image in a sequence at the optimal setting for the camera, then fix any problems in a paint program or a stitching tool.

Why limit QuickTime VR (or any immersive technology) to land based subjects? The JASON distance learning project took QTVR photograhers to Bermuda and now you can visit a page which includes tips for taking underwater panoramas.

3D Technologies
The most significant advantage of technologies that allow users to explore 3D models rather than panoramic photographs is that the user can explore all angles of the model; with the photographic technologies the user is much more limited to viewing a scene from specific locations.
This may or may not be a problem depending upon the experience you are trying to provide the user. While 3D technologies hold much promise, even with todays computers, creating a fluid and realistic scene requires lots of processing power (and if the experience is on the web, the files can become quite large; particularly as you add texture files to improve the quality of the scenes.)
VRML has received a lot of press because it is an "open" standard, but there are some proprietary technologies; including MetaStream and SuperScape.

VRML

VRML (no one is sure how to pronounce it) received a lot of press when it was first released as an open standard for 3D worlds. A lot of tools have been released that support it, and most 3D programs now will at least export to a VRML file.
It's primary use has been on the web, and there are plug-ins available for Macintosh and Windows. Even so, adoption of the standard by the general public hasn't been as fast as most expected (partly because you need memory and speed for good performance, and there is little compelling content.)

At the end of 1998 SGI, who was the initial imputus behind VRML sold Cosmo Software to Platinum. The unit continues to offer the Cosmo Software, but it's unclear what Platinum plans to do with the products (they already purchase another VRML browser plug-in InterVista.)

VRML Repository <www.sdsc.edu/vrml_repository/repository.html>
Perhaps the ultimate collection of information about VRML

WorldView VRML Browser plugin <www.intervista.com>
They offer a browser for both Macs and PCs.

Cosmo Software <www.cosmosoftware.com>
Has perhaps the best viewer plugin Cosmo Player, as well as an editing environment called Cosmo Worlds. Company Status unclear (see above)

Spazz3D is a VRML authoring tool that is currently in beta. It provides tools for building 3-D scenes, animating the geometry and defining rules of interactivity which can trigger lights, sounds, and animations.

The program can output animations in GIF and AVI files as well as save the worlds in the VRML 2 file format. An integrated FTP utility uploads VRML world files, and all their dependencies to a web site. You can download it at the website.
